Dear Fellow Shareholders,

The stock market continued its advance in the first month of 2004,
prolonging last year's strong rebound after three down years. The same
factors that produced double-digit returns in a broad-based rally in 2003
were still at work in the first month of the new year: a rebounding
economy, fueled by historically low interest rates, and improving
corporate earnings. As a result, the market, as measured by the Standard &
Poor's 500 Index, was up 1.84% in the month of January 2004. With
technology leading the way, the tech-heavy Nasdaq Composite Index rose
3.15%, while the Dow Jones Industrial Average was up 0.51%. Bonds, which
had their fourth straight year of gains in 2003, albeit on a more modest
scale, also started 2004 on the right foot, producing positive total
returns.

In other news, we are pleased to inform you that on September 28, 2003, the
Boards of Directors of Canada-based Manulife Financial Corporation and
Boston-based John Hancock Financial Services, Inc., the parent company of
John Hancock Funds, unanimously voted to merge the two companies.

Please be assured that the completion of the merger -- anticipated to occur
in the first half of 2004 -- will have no effect on your investment in our
John Hancock mutual funds. Your fund's adviser and board of trustees will
remain the same, as will your relationship with your financial advisor.

The merger is subject to customary closing conditions, including receipt of
required regulatory approvals and approval by John Hancock stockholders.

Additional information on this transaction is available on our Web site:
www.jhfunds.com. If you have questions about the merger, you may also call
800-732-5543. Separately, for information about your investments in John
Hancock funds, please contact your financial advisor or our Customer
Service representatives at 800-225-5291.

MANAGERS'
REPORT

JOHN HANCOCK
Preferred Income Fund

Preferred stocks -- which are the primary emphasis of John Hancock
Preferred Income Fund -- posted solid returns during the six-month period
ended January 31, 2004, fueled in large part by favorable supply and demand
conditions. An increasing number of companies that issued preferred stocks
in years when interest rates were higher redeemed those older preferred
stocks to take advantage of the lower interest rates that prevailed during
much of the period. Those redemptions resulted in a reduced net supply of
preferred stocks. At the same time, demand burgeoned as individual and
institutional investors increasingly sought out higher-yielding
alternatives to most fixed-income securities and common stocks. Demand got
an added boost from the passage of President Bush's dividend tax-cut
package, which greatly reduced the taxes individuals pay on most stock
dividends. A dramatic rise in interest rates and bond yields in the summer
months briefly tempered an otherwise favorable backdrop for fixed-income
investments, including preferreds. But they quickly regained their footing
in the final months of the period when inflation concerns cooled, the Fed
rushed to reassure investors that it wasn't poised to raise interest rates
any time soon and favorable supply and demand conditions trumped
macroeconomic concerns.

"Preferred stocks...posted
 solid returns during the
 six-month period ended
 January 31, 2004..."

PERFORMANCE

For the six months ended January 31, 2004, John Hancock Preferred Income
Fund returned 8.20% at net asset value. By comparison, the average income
and preferred stock closed-end fund returned 13.18%, according to Lipper,
Inc. The Fund's lag stemmed primarily from our focus on high-quality
investments. Lower-quality "junk" names soared during the year in response
to stronger demand from bargain hunters, better-than-expected corporate
earnings, fewer corporate defaults and a reduction in the rate of corporate
credit downgrades. Despite the strong


2



recent showing of low-quality investments, we felt that much of the
rebound had been played out, and so we continued our emphasis on
lower-risk, higher-rated securities. In the same six-month period, the Dow
Jones Utility Average -- which tracks the performance of 15 electric and
natural gas utilities -- returned 17.55%, and the broader stock market, as
measured by the Standard & Poor's 500 Index, returned 15.22%.

LEADERS AND LAGGARDS

Some of our best-performing holdings were those issued by financial
services companies. For example, our holdings in Royal Bank of Scotland,
which we bought at what we believed were bargain prices last summer when
the Treasury and preferred markets came under pressure, performed quite
well as investors realized the value of this high-quality company. Another
winner was FleetBoston Financial, which benefited from the announced
purchase of the company by Bank of America, which is expected to result in
higher overall credit for Fleet's outstanding preferred stock. Merrill
Lynch also performed well, thanks to its strong credit rating compared with
its brokerage services group peers and enhanced earnings consistency,
resulting from what the company termed "a diversity of revenues from
multiple asset classes, client segments and geographic regions."

"Some of our best-
 performing holdings were
 those issued by financial
 services companies."

Many of our preferred stocks issued by utility companies also posted strong
returns during the period. Throughout the period, utility stocks were
powered by investors' renewed optimism about the group, as many utilities
took significant steps to reduce debt, improve their financing and shed
money-losing unregulated subsidiaries. One standout among our preferred
stock utility holdings was Interstate Power & Light, which was boosted by
investors' recognition of the company's recovery efforts and better
earnings. Improving fundamentals at Interstate also helped our common stock
holdings in its parent company, Alliant Energy Corp. Our preferred stock
holding in utility Cinergy posted good gains, as the company's
back-to-basics approach boosted its financial performance.

We also enjoyed our share of common stock winners in the utility sector.
One was NiSource, which profited from its repositioning efforts and the
better financial results that emanated from that realignment. Scottish
Power Plc turned in a good performance thanks to a growing recognition of
the value of its ownership of Pacific Corp., which has a large U.S.
electric transmission system.

[Table at top left-hand side of page entitled "Top five industry
groups 1." The first listing is Utilities 54%, the second is Banks -- United
States 10%, the third is Finance 6%, the fourth is Banks -- foreign 5% and
the fifth is REITs 4%.]

Preferred stocks issued by oil and natural gas companies also turned in
good gains as the price of those commodities remained high. Those high
energy prices, in turn, helped boost the fortunes of holdings such as
energy company Nexen.

A disappointment during the period was TECO Energy, which came under
pressure due to concerns about the company's problems from its foray into
merchant gas-fired energy. Despite these problems, we continued to hold on
to our stake in TECO because the company has very well-run electric and gas
utility operations in Florida, and because we believe it will eventually
distance itself from its merchant energy business.

[Pie chart in middle of page with heading "Portfolio diversification 1"
The chart is divided into five sections (from top to left): Preferred
stocks 83%, Capital preferred securities 7%, Common stocks 4%,

OUTLOOK

In our view, the first half of 2004 likely will continue to favor preferred
and utility stocks. First off, we believe that both sectors will keep on
benefiting from the favorable supply and demand conditions that boosted
their prospects over the past six months. Our interest-rate forecast --
which calls for continued low interest rates -- should also help preferreds
because they pay dividends at a fixed rate like the interest on a bond and,
as such, tend to perform best when rates decline or stabilize at relatively
low levels, just as bonds do. Although the


4



economy has heated up, we don't think that the Federal Reserve Board will
raise interest rates until the current recovery deepens and sustains
itself for a longer period of time. Granted, longer-term bond yields could
rise as investors worry about the prospects of future inflation, but the
expected lack of an interest-rate hike would keep short-term interest
rates low, thereby making preferred stocks an attractive alternative to
shorter-term, lower-yielding money market and Treasury securities.
Furthermore, we believe investors' appetite for preferred stocks and
utility common stocks -- many of which benefit from the new lower federal
tax on dividends -- could remain strong. In addition to robust demand,
utility common stocks appear to have other factors working in their favor.
Chief among them are the potential for more stable credit ratings and
continued attractive valuations -- albeit higher than at the beginning of
2003 -- relative to the stock market overall. Recent acquisitions of
utility companies by deep-pocketed private equity investors may signal
that more acquisition activity is in the offing in 2004, a trend that
could help boost utilities.

"In our view, the first half
 of 2004 likely will continue
 to favor preferred and
 utility stocks."

This commentary reflects the views of the portfolio management team through
the end of the Fund's period discussed in this report. The team's
statements reflect their own opinions. As such, they are in no way
guarantees of future events, and are not intended to be used as investment
advice or a recommendation regarding any specific security. They are also
subject to change at any time as market and other conditions warrant.

The Fund normally will invest at least 25% of its managed assets in
securities of companies in the utilities industry. Such an investment
concentration makes the Fund more susceptible than a broader diversified
fund to factors adversely affecting the utilities industry. Sector
investing is subject to greater risks than the market as a whole.

NOTES TO
STATEMENTS

Unaudited

NOTE A
Accounting policies

John Hancock Preferred Income Fund (the "Fund") is a diversified closed-end
management investment company registered under the Investment Company Act
of 1940.

Significant accounting policies of the Fund are as follows:

Valuation of investments

Securities in the Fund's portfolio are valued on the basis of market
quotations, valuations provided by independent pricing services or at fair
value, as determined in good faith, in accordance with procedures approved
by the Trustees. Short-term debt investments maturing within 60 days are
valued at amortized cost, which approximates market value. The Fund
determines the net asset value of the common shares each business day.

Investment transactions

Investment transactions are recorded as of the date of purchase, sale or
maturity. Net realized gains and losses on sales of investments are
determined on the identified cost basis.

Discount and premium on securities

The Fund accretes discount and amortizes premium from par value on
securities from either the date of issue or the date of purchase over the
life of the security.

Expenses

The majority of expenses are directly identifiable to an individual fund.
Expenses that are not readily identifiable to a specific fund are allocated
in such a manner as deemed equitable, taking into consideration, among
other things, the nature and type of expense and the relative sizes of the
funds.

Financial futures contracts

The Fund may buy and sell financial futures contracts. Buying futures tends
to increase the Fund's exposure to the underlying instrument. Selling
futures tends to decrease the Fund's exposure to the underlying instrument
or hedge other Fund's instruments. At the time the Fund enters into a
financial futures contract, it is required to deposit with its custodian a
specified amount of cash or U.S. government securities, known as "initial
margin," equal to a certain percentage of the value of the financial
futures contract being traded. Each day, the futures contract is valued at
the official settlement price of the board of trade or U.S. commodities
exchange on which it trades. Subsequent payments to and from the broker,
known as "variation margin," are made on a daily basis as the market price
of the financial futures contract fluctuates. Daily variation margin
adjustments arising from this "mark to market" are recorded by the Fund as
unrealized gains or losses.


17



When the contracts are closed, the Fund recognizes a gain or loss. Risks of
entering into financial futures contracts include the possibility that
there may be an illiquid market and/or that a change in the value of the
contracts may not correlate with changes in the value of the underlying
securities. In addition, the Fund could be prevented from opening or
realizing the benefits of closing out financial futures positions because
of position limits or limits on daily price fluctuation imposed by an
exchange.

For federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of financial futures
contracts. On January 31, 2004, the Fund had deposited $325,000 in a
segregated account to cover margin requirements on open financial futures
contracts.

The Fund had the following open financial futures contracts on
January 31, 2004:

                   NUMBER OF
OPEN CONTRACTS     CONTRACTS      POSITION      EXPIRATION       APPRECIATION
-----------------------------------------------------------------------------
U.S. 10-Yr Note      250           Short          MAR 04           $106,844


Swap contracts

The Fund may enter into swap transactions in order to hedge the value of
the Fund's portfolio against interest rate fluctuations or to enhance the
Fund's income. Interest rate swaps represent an agreement between two
counterparties to exchange cash flows based on the difference in the two
interest rates, applied to the notional principal amount for a specified
period. The payment flows are usually netted against each other, with the
difference being paid by one party to the other.

Accrued interest receivable or payable on the swap contracts is recorded
daily as interest income or as an offset to interest income. The Fund
settles accrued net receivable or payable under the swap contracts on a
periodic basis. The Fund records changes in the value of the swaps as
unrealized gains or losses on swap contracts and records realized gains or
losses at the time the swap contracts are closed out.

Swap contracts are subject to risks related to the counterparty's ability
to perform under the contract, and may decline in value if the
counterparty's creditworthiness deteriorates. The risks may arise from
unanticipated movement in interest rates. The Fund may also suffer losses
if it is unable to terminate outstanding swap contracts or reduce its
exposure through offsetting transactions.

The Fund had the following interest rate swap contracts open on January 31,
2004:

                           RATE TYPE
                  -----------------------------

(a) Fixed rate


Federal income taxes

The Fund qualifies as a "regulated investment company" by complying with
the applicable provisions of the Internal Revenue Code and will not be
subject to federal income tax on taxable income that is distributed to
shareholders. Therefore, no federal income tax provision is required.


18



Dividends, interest and distributions

Dividend income on investment securities is recorded on the ex-dividend
date or, in the case of some foreign securities, on the date thereafter
when the Fund identifies the dividend. Interest income on investment
securities is recorded on the accrual basis. Foreign income may be subject
to foreign withholding taxes, which are accrued as applicable.

The Fund records distributions to shareholders from net investment income
and net realized gains on the ex-dividend date.

Such distributions, on a tax basis, are determined in conformity with
income tax regulations, which may differ from accounting principles
generally accepted in the United States of America. Distributions in excess
of tax-basis earnings and profits, if any, are reported in the Fund's
financial statements as a return of capital.

Use of estimates

The preparation of these financial statements, in accordance with
accounting principles generally accepted in the United States of America,
incorporates estimates made by management in determining the reported
amount of assets, liabilities, revenues and expenses of the Fund. Actual
results could differ from these estimates.

NOTE B
Management fee and transactions with affiliates and others

The Fund has an investment management contract with John Hancock Advisers,
LLC (the "Adviser"), a wholly owned subsidiary of the Berkeley Financial
Group, LLC. Under the investment management contract, the Fund pays a daily
management fee to the Adviser at an annual rate of 0.75% of the Fund's
average daily net assets and the value attributable to the Auction
Preferred Shares ("managed assets").

The Adviser has contractually agreed to limit the Fund's management fee to
the following: 0.55% of the Fund's average daily managed assets until the
fifth anniversary of the commencement of the Fund's operations, 0.60% of
such assets in the sixth year, 0.65% of such assets in the seventh year and
0.70% of average daily managed assets in the eighth year. Accordingly, the
expense reductions related to the reduction in the management fee amounted
to $934,176 for the period ended January 31, 2004. After the eighth year,
the Adviser will no longer waive a portion of the management fee.

The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the period
was at an annual rate of 0.03% of the average managed assets of the Fund.
The Fund also paid the Adviser the amount of $1,078 for certain publishing
services, included in the printing fees.

Ms. Maureen Ford Goldfarb and Mr. John M. DeCiccio are directors and/or
officers of the Adviser and/or its affiliates, as well as Trustees of the
Fund. The compensation of unaffiliated Trustees is borne by the Fund. The
unaffiliated Trustees may elect to defer, for tax purposes, their receipt
of this compensation under the John Hancock Group of Funds Deferred Compen
sation Plan. The Fund makes investments into other John Hancock funds, as
applicable, to cover its liability for the deferred compensation.
Investments to cover the Fund's deferred compensation liability are
recorded on the Fund's books as an other asset. The deferred compensation
liability and the related other asset are always equal and are marked to
market on a periodic basis to reflect any income earned by the investments,
as well as any unrealized gains or losses. The Deferred Compensation Plan
investments had no impact on the operations of the Fund.

Auction preferred shares

The Fund issued a total of 11,200 Auction Preferred Shares (2,240 shares of
Series M, 2,240 shares of Series T, 2,240 shares of Series W, 2,240 of
shares of Series TH and 2,240 shares of Series F) (collectively, the "APS")
on October 23, 2002, in a public offering. The underwriting discount of
$2,800,000 has been charged to capital paid-in of common shares during the
period ended July 31, 2003.

Offering costs of $617,673 related to common shares and offering costs of
$385,442 incurred in connection with the preferred shares were charged to
the Fund's capital paid-in during the period ended July 31, 2003.

Dividends on the APS, which accrue daily, are cumulative at a rate that was
established at the offering of the APS and has been reset every 7 days
thereafter by an auction (except for the Series W, which reset its rate on
October 23, 2003, at which time the Fund elected a Special Dividend Payment
of 182 days for the subsequent distributions). Dividend rates on the APS
ranged from 0.95% to 1.59% during the period ended January 31, 2004.
Accrued dividends on the APS are included in the value of the APS on the
Fund's Statement of Assets and Liabilities.

The APS are redeemable at the option of the Fund, at a redemption price
equal to $25,000 per share, plus accumulated and unpaid dividends on any
dividend payment date. The APS are also subject to mandatory redemption at
a redemption price equal to $25,000 per share, plus accumulated and unpaid
dividends, if the Fund is in default on its asset coverage requirements
with respect to the APS, as defined in the Fund's by-laws. If the dividends
on the APS shall remain unpaid in


20



an amount equal to two full years' dividends, the holders of the APS, as a
class, have the right to elect a majority of the Board of Trustees. In
general, the holders of the APS and the common shareholders have equal
voting rights of one vote per share, except that the holders of the APS,
as a class, vote to elect two members of the Board of Trustees, and
separate class votes are required on certain matters that affect the
respective interests of the APS and common shares.

NOTE D
Investment
transactions

Purchases and proceeds from sales or maturities of securities, other than
short-term securities and obligations of the U.S. government, during the
period ended January 31, 2004, aggregated $99,824,110 and $108,337,745,
respectively.

The cost of investments owned on January 31, 2004, including short-term
investments, for federal income tax purposes, was $887,067,063. Gross
unrealized appreciation and depreciation of investments aggregated
$58,751,754 and $7,281,462, respectively, resulting in net unrealized
appreciation of $51,470,292. The appreciation of swap contracts, for
federal tax purposes, was $2,226,866. The difference between book basis and
tax basis net unrealized appreciation of investments is attributable
primarily to amortization of premiums and accretion of discounts on debt
securities.

INVESTMENT
OBJECTIVE
AND POLICY

The Fund's primary objective is to provide a high level of current income,
consistent with preservation of capital. The Fund's secondary objective is
to provide growth of capital to the extent consistent with its primary
objective. The Fund seeks to achieve its objectives by investing in a
diversified portfolio of securities that, in the opinion of the Adviser,
may be undervalued relative to similar securities in the marketplace.

Under normal market conditions, the Fund invests at least: (a) 80% of its
assets in preferred stocks and other preferred securities, including
convertible preferred securities, (b) 25% of its total assets in the
industries comprising the utilities sector and (c) 80% of its total assets
in preferred securities or other fixed-income securities, which are rated
investment grade or higher by Moody's or Standard & Poor's at the time of
investment. "Assets" are defined as net assets, including the liquidation
preference of APS, plus borrowing for investment purposes.

Effective December 16, 2003, the Trustees approved additional changes to
the Fund's by-laws. The changes included updating the leveraged rating
agency requirements in keeping with recent changes to the agency's basic
maintenance reporting requirements for leveraged closed-end funds. In
addition, changes were made to reflect recent updates that Moody's made to
some of their eligible asset and discount factors. These revisions bring
the Fund's by-laws in line with current rating agency requirements.

DIVIDEND
REINVESTMENT PLAN

The Fund offers its shareholders a Dividend Reinvestment Plan (the "Plan"),
which offers the opportunity to earn compounded yields. Each holder of
common shares will automatically have all distributions of dividends and
capital gains reinvested by Mellon Investor Services, as Plan Agent for the
common shareholders (the "Plan Agent"), unless an election is made to
receive cash. Holders of common shares who elect not to participate in the
Plan will receive all distributions in cash, paid by check and mailed
directly to the shareholder of record (or, if the common shares are held in
street or other nominee name, then to the nominee) by the Plan Agent, as
dividend-disbursing agent. Shareholders whose shares are held in the name
of a broker or a nominee should contact the broker or nominee to determine
whether and how they may participate in the Plan.

If the Fund declares a dividend payable either in common shares or in cash,
non-participants will receive cash and participants in the Plan will
receive the equivalent in common shares. If the market price of the common
shares on the payment date of the dividend is equal to, or exceeds, their
net asset value as determined on the payment date, participants will be
issued common shares (out of authorized but unissued shares) at a value
equal to the higher of net asset value or 95% of the market price. If the
net asset value exceeds the market price of the common shares at such time,
or if the Board of Trustees declares a dividend payable only in cash, the
Plan Agent will, as agent for Plan participants, buy shares in the open
market, on the New York Stock Exchange or elsewhere, for the participant's
accounts. Such purchases will be made promptly after the payable date for
such dividend and, in any event, prior to the next ex-dividend date after
such date, except where necessary to comply with federal securities laws.
If, before the Plan Agent has completed its purchases, the market price
exceeds the net asset value of the common shares, the average per share
purchase price paid by the Plan Agent may exceed the net asset value of the
common shares, resulting in the acquisition of fewer shares


22



than if the dividend had been paid in shares issued by the Fund.

Each participant will pay a pro rata share of brokerage commissions
incurred with respect to the Plan Agent's open market purchases in
connection with the reinvestment of dividends and distributions. The cost
per share of the shares purchased for each participant's account will be
the average cost, including brokerage commissions, of any shares purchased
on the open market, plus the cost of any shares issued by the Fund. There
will be no brokerage charges with respect to common shares issued directly
by the Fund. There are no other charges to participants for reinvesting
dividends or capital gain distributions.

Participants in the Plan may withdraw from the Plan at any time by
contacting the Plan Agent by telephone, in writing or by visiting the Plan
Agent's Web site at www.melloninvestor.com. Such withdrawal will be
effective immediately if received not less than 10 days prior to a dividend
record date; otherwise, it will be effective for all subsequent dividend
record dates. When a participant withdraws from the Plan or upon
termination of the Plan, as provided below, certificates for whole common
shares credited to his or her account under the Plan will be issued and a
cash payment will be made for any fraction of a share credited to such
account.

The Plan Agent maintains each shareholder's account in the Plan and
furnishes monthly written confirmations of all transactions in the
accounts, including information needed by the shareholders for personal and
tax records. The Plan Agent will hold common shares in the account of each
Plan participant in non-certificated form in the name of the participant.
Proxy material relating to the shareholders' meetings of the Fund will
include those shares purchased, as well as shares held pursuant to the
Plan.

The reinvestment of dividends and distributions will not relieve
participants of any federal income tax that may be payable or required to
be withheld on such dividends or distributions. Participants under the Plan
will receive tax information annually. The amount of dividend to be
reported on the 1099-DIV should be: (1) in the case of shares issued by the
Fund, the fair market value of such shares on the dividend payment date and
(2) in the case of shares purchased by the Plan Agent in the open market,
the amount of cash used by the Plan Agent to purchase shares in the open
market, including the amount of cash allocated to brokerage commissions
paid on such purchases.

Experience under the Plan may indicate that changes are desirable.
Accordingly, the Fund reserves the right to amend or terminate the Plan as
applied to any dividend or distribution paid subsequent to written notice
of the change sent to all shareholders of the Fund at least 90 days before
the record date for the dividend or distribution. The Plan may be amended
or terminated by the Plan Agent after at least 90 days' written notice to
all shareholders of the Fund. All correspondence or additional information
concerning the Plan should be directed to the Plan Agent, Mellon Bank,
N.A., c/o Mellon Investor Services, P.O. Box 3338, South Hackensack, NJ
07606-1938 (telephone 1-800-852-0218).
