Dear Fellow Shareholders,

After starting 2003 with a bang, the stock market quickly gave in to the
continuing pressures that plagued it throughout 2002. The threat of war
with Iraq increased and terrorism fears grew. The uncertainty surrounding
these and other geopolitical issues became uppermost in investors' minds
and caused the market to continue the tumble that marked 2002. In the month
of January, the Dow Jones Industrial Average returned -3.24%, the Standard
& Poor's 500 Index lost 2.61% and the Nasdaq Composite Index lost 1.09%.
Bonds remained essentially flat in January, with the exception of
lower-grade high-yield bonds, which continued a rally they began in the
fourth quarter of 2002.

January's results matched the trend of the last three years, in which
stocks lost ground every year as the economy stalled, corporate spending
and profits were lackluster and investor confidence plunged amid
corporate scandals. Bonds, on the other hand, outperformed stocks for a
third straight year and produced positive results in 2002, while 96% of
U.S. diversified stock mutual funds lost money. These results only
confirm the importance of having a portfolio well-diversified among
stocks, bonds and cash.

In fact, the disparity between stock and bond results over the last
three years means that many investors' portfolios may have shifted
substantially in their mix between stocks and bonds. We recommend
working with your investment professional to rebalance your assets
according to your long-term goals.

After three down years, no one can predict when the bear market cycle
will turn. Currently, uncertainties abound, with ongoing concerns about
the economy and the possibility of war and other geopolitical risks.

While all these factors are beyond our control, investors can take
charge of how they maneuver through the inevitable bull and bear market
cycles. We've said it before, but it bears repeating: the key is to keep
a long-term perspective and work with your investment professional to
develop and maintain a properly diversified portfolio. We believe this
offers the best protection in tough times and the best means to reach
your long-term goals.

Sincerely,

/S/ MAUREEN R. FORD

Maureen R. Ford,
Chairman and Chief Executive Officer



YOUR FUND
AT A GLANCE

The Fund seeks
to provide a high
level of current
income, consistent
with preservation
of capital, by
investing in a
diversified portfo-
lio of securities
that, in the opin-
ion of the Adviser,
may be underval-
ued relative to
similar securities
in the marketplace.
Under normal mar-
ket conditions, the
Fund invests at
least 80% of assets
in preferred stocks
and other pre-
ferred securities.

Over the last six months

* Preferred stocks performed relatively well, driven by falling interest
  rates and strong demand.

* Since the Fund's inception in August 2002, the investment team has
  been assembling a diversified portfolio of stocks offering value and
  strong fundamentals.

* Oil and natural gas-related holdings performed best as prices of both
  commodities soared.

MANAGERS'
REPORT

PORTFOLIO MANAGEMENT TEAM

John Hancock
Preferred Income Fund

From the inception of John Hancock Preferred Income Fund on August 27,
2002, through January 31, 2003, preferred stocks turned in relatively
good performances compared to U.S. common stocks. Much of preferred
stocks' gains were driven by falling interest rates, which continued to
drift lower in late summer and early fall 2002 in response to a weak
economy. That trend continued throughout the remainder of the period,
fueled by a surprise half percentage point rate cut by the Federal
Reserve Board in November. Preferred stocks pay dividends, just like
bonds pay regular interest, and, like bonds, their prices tend to rise
when interest rates fall.

"...preferred stocks turned
 in relatively good perfor
 mances compared to U.S.
 common stocks."

Another factor helping the preferred-stock market was strengthening
demand from income-seeking investors looking for significantly higher
yields than what companies were paying on their bonds and common stocks.
Many preferred stocks continued to yield between 7% and 9%, outstripping
by a fairly wide margin the yields paid by corporate and other bonds and
the dividends paid by common stocks. Demand further strengthened in
December and January when a number of newly launched mutual funds
focusing on preferred stocks began to invest their assets. In the final
month of the period, the preferred market got an added boost from
President Bush's proposal to eliminate the double taxation of dividends.
Even though most of the preferred stocks that the Fund focuses on won't
enjoy tax relief from this proposal, since their dividends are paid in
pre-tax dollars, their prices were lifted by the development.

FUND PERFORMANCE

From its inception on August 27, 2002 through January 31, 2003, John
Hancock Preferred Income Fund returned 2.22% at net asset value. Over
the same period, the Standard & Poor's 500 Index returned -7.74% and
the average income and preferred stock closed-end fund returned 0.56%.

OUR INVESTMENT PROCESS

Our investment philosophy is a fairly straightforward, time-tested
process guided by our experienced team of portfolio managers and
security analysts. The Fund's primary objective is to provide a high
level of current income consistent with preservation of capital. We seek
to produce superior results by focusing on the business cycle and
individual security fundamentals. This focus on fundamentals means we
don't just chase yield. High yield often suggests additional risk --
particularly a heightened sensitivity to interest-rate changes or lower
credit quality. We prefer to avoid making bets on the direction of
interest rates by altering the Fund's interest-rate sensitivity, and we
keep a minimum of 80% of the Fund's investments in investment-grade
preferred stocks and bonds. In structuring the portfolio, we seek to add
investment value in two ways. First, we try to anticipate broader, more
gradual changes in the business cycle, and then invest in those
industries and sectors that are expected to benefit from the changes.
Second, we look within those industries and sectors for issuers and
companies that are undervalued and mispriced relative to the market
overall.

"...we have found some of
 the best combinations of
 value and good fundamen-
 tals primarily in the utility,
 financial services and oil
 and gas industry groups..."

DIVERSIFICATION IS KEY

We also put a premium on diversifying the portfolio among a number of
industry groups. Since the Fund began operations, we have found some of
the best combinations of value and good fundamentals primarily in the
utility, financial services and oil and gas industry groups. Among
utilities, we favored domestic, regionally based utility companies that
have little or no unregulated operations. One of our larger holdings in
this area at the end of the period was Dominion Resources. We like the
company because of its large, core base of regulated gas and electric
utility operations, its major natural gas pipeline operations and its
very profitable oil and natural gas production capabilities. Among
financial institutions, we emphasized large domestic money center banks
and large broker service companies such ING Groep, an international
financial services company with a strong track record of successfully
entering new markets.

[Table at top left-hand side of page entitled "Top five industry
groups 1." The first listing is Utilities 55%, the second is Banks--United
States 8%, the third Finance 6%, the fourth Oil & gas 5%, and the fifth
REITs 3%.]

[Pie chart in middle of page with heading "Portfolio diversification 1"
The chart is divided into four sections (from top to left): Common
stocks 3%, Preferred stocks 88%, Corporate bonds 2% and Short-term
investments & other 7%.]

LEADERS AND LAGGARDS

As for oil and gas producers, our favorite and one of our best
performers during the period was Nexen, Inc., a Canadian oil and natural
gas production company with significant international oil production.
The run-up in oil prices -- which also helped pump up natural gas prices
-- caused companies involved in the production and distribution of oil
and natural gas to be among our best performers in the period. Despite
relatively anemic global demand for energy, oil and natural gas prices
skyrocketed as the year wore on, due to growing concerns about the oil
strike in Venezuela and a possible U.S. attack on Iraq that may disrupt
oil supplies.

[Table at top of page entitled "SCORECARD." The header for the left
column is "INVESTMENT" and the header for the right column is "RECENT
PERFORMANCE...AND WHAT'S BEHIND THE NUMBERS." The first listing is
Nexen, Inc. followed by an up arrow with the phrase "Oil prices spike
amid fears of Iraq war." The second listing is Energy East followed by
an up arrow with the phrase "Demand for high-yielding stocks boosts
price." The third listing is El Paso Tennessee Pipeline followed by a
down arrow with the phrase "Company's role in California power crisis
questioned."]

On the flip side was El Paso Corp. and its wholly owned subsidiary
Coastal. Those holdings came under pressure when a judge ruled that the
company had manipulated pipeline capacity during the 2001 California
power crisis. We think the company will be exonerated in its appeal to
the Federal Energy Regulatory Commission.

"Low interest rates
 should continue to
 prompt strong demand
 for preferred stocks..."

OUTLOOK

Our view is that continued lackluster economic growth will preclude the
need for interest rate hikes for the foreseeable future. Low interest
rates should continue to prompt strong demand for preferred stocks from
all types of investors seeking alternatives to low-yielding money market
investments and higher-yielding, but more risky, types of taxable bonds.
Another factor likely to ignite demand is President Bush's proposal to
eliminate taxes on some dividends. In the weeks following that
announcement, many investors started to put higher values on many
dividend-producing stocks.

This commentary reflects the views of the portfolio management team
through the end of the Fund's period discussed in this report. Of
course, the team's views are subject to change as market and other
conditions warrant.

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 the expenses are directly identifiable to an individual
fund. Expenses that are not readily identifiable to a specific fund will
be 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.

Organization expenses and offering costs

Expenses incurred in connection with the organization of the Fund, which
amounted to $53,000, have been borne by the Fund. Offering costs of
$819,000 related to common shares and offering costs of $482,000
incurred in connection with the preferred shares were charged to the
Fund's common shares capital paid-in.

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.

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 monthly 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 reduction in the management fee amounted to
$656,422 for the period ended January 31, 2003. 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 approximately 0.03% of the average
managed assets of the Fund.

Ms. Maureen R. Ford 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 Compensation 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 investment 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.

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, for which the
initial reset date will be April 23, 2003). Dividend rates on APS ranged
from 1.25% to 1.95% during the period ended January 31, 2003. Accrued
dividends on APS are included in the value of 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 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 of securities, other than short-term
securities and obligations of the U.S. government, during the period
ended January 31, 2003, aggregated $2,296,050,877 and $52,574,620,
respectively.

The cost of investments owned on January 31, 2003, including short-term
investments, for federal income tax purposes was $896,970,734. Gross
unrealized appreciation and depreciation of investments aggregated
$15,859,708 and $18,972,470, respectively, resulting in net unrealized
depreciation of $3,112,762.

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.

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 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 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, except for
certain brokerage commissions, as described above.

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 ten 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 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).
