Dear Fellow Shareholders,

The stock market advanced for the second straight year, largely on the wings
of a strong post-election rally that produced solid returns for the major
indexes in 2004. For much of the year, the market was fairly dull, moving
mostly sideways as investors worried about higher interest rates,
sky-rocketing oil prices, the tight presidential election and the war in
Iraq. With the election over and oil prices moderating, investors felt more
confident, and the broad Standard & Poor's 500 Index wound up returning
10.88% for the year. The Dow Jones Industrial Average returned 5.40% and a
late and strong rally in technology stocks helped the Nasdaq Composite Index
move from a negative stance in October to finish the year with a 9.15%
return. Despite the Federal Reserve's five hikes in short-term interest
rates, bonds still turned in positive results, with the Lehman Brothers
Aggregate Bond Index up 4.34%.

The way this year has played out in the financial markets serves as a good
reminder of why keeping a long-term perspective is such a critical element
of successful investing. Getting caught up in the day-to-day twists and
turns of the market -- and trying to act on them -- can wreak havoc with
your portfolio and derail progress toward meeting your overall financial

Since no one can predict the market's moves, the best way to reach your
goals is to stay invested and stick to your plan. Investing should be a
marathon, not a sprint. Do not try to time the market, and make sure you
work with your investment professional to ensure that your portfolio remains
properly diversified to meet your long-term objectives. For example, after
several years of dominance, small-cap stocks and value stocks could now
represent higher percentages of your portfolio than you may want. If you are
comfortable with your financial plan, it becomes easier to ride out the
market's daily ups and downs. It could also provide you with a greater
chance of success over time.

Patriot Select Dividend Trust

Preferred stocks posted strong gains during the six-month period ended
December 31, 2004. The period began on somewhat of a sour note following a
spring Treasury market sell-off that was triggered by robust economic
reports which fanned fears of higher inflation and interest rates. Because
preferreds make fixed-income payments in the form of dividends, their
prices, like bond prices, tend to move in the opposite direction of interest
rates. Even though the Federal Reserve Board did raise rates a quarter of a
percentage point on four separate occasions during the period, the bond and
preferred markets continued to rally. Investors also viewed the re-election
of President George Bush as a positive for tax-advantaged preferred stocks.
The president vowed to make permanent a recent reduction in the tax rate
most individuals pay on many stock dividends. Finally, preferreds benefited
from favorable supply and demand conditions. Supply dwindled as companies
redeemed their outstanding preferred stock as a way of reducing their
financing costs, and there wasn't much in the way of new issuance.
Meanwhile, demand was strong as investors continued to seek out the
relatively high dividends and quality of preferred stocks.

"Preferred stocks posted strong
 gains during the six-month period
 ended December 31, 2004."

Although the performance of preferred stocks was impressive for the
six-month period, utility common stocks posted even stronger gains.
Investors continued to pour money into the group, attracted by two main
factors. First was the lure of high dividends, many of which were
tax-advantaged. Second was the group's continued fundamental improvement,
evidenced by reduced debt levels, improved balance sheets and the sale or
closure of money-losing unregulated subsidiaries.

For the six months ended December 31, 2004, John Hancock Patriot Select
Dividend Trust returned 14.78% at net asset value and 10.75% at market
value. The difference in the Fund's net asset value (NAV) performance and
its market performance stems from the fact that the market share price is
subject to the dynamics of secondary market trading, which could cause it to
trade at a discount or premium to the Fund's NAV share price at any time. By
comparison, the average income and preferred stock closed-end fund returned
12.95% at net asset value, according to Lipper, Inc. In the same six-month
period, the Dow Jones Utility Average -- which tracks the performance of 15
electric and natural gas utilities -- returned 22.75%, and the broader stock
market, as measured by the Standard & Poor's 500 Index, returned 7.19%.

"Many of our utility common
 stock holdings also were our best
 performers for the period."

Utility common stock holdings shine

Many of our utility common stock holdings also were our best performers for
the period. Among the best was KeySpan Corp., the largest natural gas
distributor in the Northeast United States. The stock already had a lot
going for it because it had an attractive yield. But it really got a boost
from the success of its growing customer base and news that the company
would increase its dividend. DTE Energy also performed well, hitting a
52-week high during the period. The stock offered an attractive dividend
yield and was further aided by the favorable resolution of a major utility
rate case in its home state of Michigan.

Tax-advantaged preferred stocks do well

Given expectations that the 2003 tax reform bill would be made permanent
because of the re-election of President Bush and the larger Republican
majority in both the House and Senate, tax-advantaged preferred stocks were
in heavy demand and turned in good gains during the period. A good example
was Southern Union, which also was helped by investors' expectations that
the company would receive a credit-rating upgrade. Sierra Pacific Power
benefited from its efforts to repair its balance sheet. In the financial
sector, our holdings in Bear Stearns did well thanks to the combination of
its attractive dividend and the strong financial performance of the


company. On the flip side, we continued to be disappointed by our holdings
in multi-state energy provider Aquila, an electric and gas energy company
that has been punished by investors after retreating from the wholesale
energy-trading markets. Even though Aquila made some progress toward
resolving its problems, our patience wore thin and we sold our holdings in
the company to look for more attractive opportunities elsewhere.

A word about dividends

Issuers exercising their call provisions to benefit from falling interest
rates last year caused the supply of preferred stocks to shrink, and
virtually every week other issuers continued to announce additional calls of
preferred stocks. From a technical standpoint, calls largely have been
beneficial for the preferred stock market because they have reduced
available supply. By the same token, however, the Fund has been forced
either to surrender to calls some of its higher-yielding preferred stock
holdings and reinvest the proceeds in securities that carried lower dividend
yields or to hold on to cash or equivalents. At the same time, rising
interest rates forced the cost of leverage higher. The resulting downward
pressure on the Fund's dividend income, coupled with the rising cost of
leverage, caused us to reduce our monthly dividend on December 30, 2004. The
new dividend amount of $0.0750 equates to an annualized yield of 5.97%,
based on the Fund's closing market price as of December 29, 2004.

In our view, the late 2004 decline in oil prices and reports of better
economic data suggest that the Fed will continue on a measured path to raise
short-term interest rates. Although the rate hikes that were enacted
throughout the period haven't yet hurt the prices of preferred stocks, it's
possible that potentially higher long-term interest rates could dampen their
performance over the near term. As for utility stocks, we wouldn't be
altogether surprised if they are poised for a breather or even a pullback
over the short term given their rapid and recent impressive gains. Over the
longer term, however, there are a couple of factors we believe will continue
to work in favor of both preferred and utility common stocks. Making
permanent the recently reduced dividend tax rate and strong demand from an
aging American population potentially more intent on shifting assets to
high-quality income-producing securities should provide some support for the
group even if long-term bond yields rise.

"As for utility stocks, we wouldn't be
 altogether surprized if they are
 poised for a breather..."

This commentary reflects the views of the portfolio managers through the end
of the Fund's period discussed in this report. The managers' statements
reflect their own opinions. As such, they are in no way guarantees of future

The Fund normally will invest more than 65% of its managed assets in
securities of companies in the utilities industry. Such an investment
concentration makes the Fund more susceptible to factors adversely affecting
the utilities industry than a more broadly diversified fund. Sector
investing is subject to greater risks than the market as a whole.

Note A
Accounting policies

John Hancock Patriot Select Dividend Trust (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, which have a remaining maturity
of 60 days or less may be 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.


The majority of the 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.

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, if any, on the ex-dividend date. During the year
ended June 30, 2004, the tax character of distributions paid was as follows:
ordinary income -- $11,520,726. 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 John Hancock Financial
Services, Inc. Under the investment management contract, the Fund pays a
monthly management fee to the Adviser at an annual rate of 0.80% of the
Fund's average weekly net assets plus the value attributable to the
preferred shares (collectively, "managed assets").

The Fund has an administrative agreement with the Adviser under which the
Adviser oversees the custodial, auditing, valuation, accounting, legal,
stock transfer and dividend disbursing services and maintains Fund
communications with shareholders. The Fund pays the Adviser a monthly
administration fee at an annual rate of 0.15% of the Fund's average weekly
managed assets, which amounted to $158,875 during the period ended December
31, 2004.

Mr. James A. Shepherdson is a director and officer of the Adviser, as well
as affiliated Trustee of the Fund, and is compensated by the Adviser. 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 investment as well as any
unrealized gains or losses. The Deferred Compensation Plan investments had
no impact on the operations of the Fund.

Auction Market Preferred
Shares Series A

The Fund issued 700 shares of Dutch Auction Market Preferred Shares Series A
("AMPS") on August 30, 1990, in a public offering. The underwriting discount
was recorded as a reduction of the capital of common shares.

Dividends on the AMPS, which accrue daily, are cumulative at a rate that was
established at the offering of the AMPS and has been reset every 49 days
thereafter by an auction. Dividend rates on AMPS ranged from 1.27% to 2.09%
during the period ended December 31, 2004. Accrued dividends on AMPS are
included in the value of AMPS on the Fund's Statement of Assets and

The AMPS are redeemable at the option of the Fund, at a redemption price
equal to $100,000 per share, plus accumulated and unpaid dividends on any
dividend payment date. The AMPS are also subject to mandatory redemption at
a redemption price equal to $100,000 per share, plus accumulated and unpaid
dividends, if the Fund is in default on its asset coverage requirements with
respect to the AMPS, as defined in the Fund's by-laws. If the dividends on
the AMPS shall remain unpaid in an amount equal to two full years'
dividends, the holders of the AMPS, as a class, have the right to elect a
majority of the Board of Trustees. In general, the holders of the AMPS and
the common shareholders have equal voting rights of one vote per share,
except that the holders of the AMPS, 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 AMPS and common

Note D

Purchases and proceeds from sales of securities, other than short-term
securities and obligations of the U.S. government, during the period ended
December 31, 2004, aggregated $43,037,430 and $41,687,666, respectively.

The cost of investments owned on December 31, 2004, including short-term
investments, for federal income tax purposes was $212,690,017. Gross
unrealized appreciation and depreciation of investments aggregated
$15,163,860 and $10,629,626, respectively, resulting in net unrealized
appreciation of $4,534,234. The difference between book basis and tax basis
net unrealized appreciation of investments is attributable primarily to the
tax deferral of losses on certain sales of securities.


and policy

The Fund's investment objective is to provide high current income,
consistent with modest growth of capital. The Fund seeks to achieve its
investment objective by investing in preferred stocks that, in the opinion
of the Adviser, may be undervalued relative to similar securities in the

The Fund's non-fundamental investment policy, which became effective October
15, 1994, stipulates that preferred stocks and debt obligations in which the
Fund will invest will be rated investment-grade (at least "BBB" by S&P or
"Baa" by Moody's) at the time of investment or will be preferred stocks of
issuers of investment-grade senior debt, some of which may have speculative
characteristics or, if not rated, will be of comparable quality as
determined by the Adviser. The Fund will invest in common stocks of issuers
whose senior debt is rated investment-grade or, in the case of issuers that
have no rated senior debt outstanding, whose senior debt is considered by
the Adviser to be of comparable quality.

On November 20, 2001, the Fund's Trustees approved the following investment
policy investment restriction change, effective December 15, 2001. Under
normal circumstances, the Fund will invest at least 80% of its assets in
dividend-paying securities. The "Assets" are defined as net assets and the
liquidation preference amount of the AMPS plus borrowings for investment
purposes. The Fund will notify shareholders at least 60 days prior to any
change in this 80% investment policy.


In November 2002, the Board of Trustees adopted several amendments to the
Fund's by-laws, including provisions relating to the calling of a special
meeting and requiring advance notice of shareholder proposals or nominees
for Trustee. The advance notice provisions in the by-laws require
shareholders to notify the Fund in writing of any proposal which they intend
to present at an annual meeting of shareholders, including any nominations
for Trustee, between 90 and 120 days prior to the first anniversary of the
mailing date of the notice from the prior year's annual meeting of
shareholders. The notification must be in the form prescribed by the
by-laws. The advance notice provisions provide the Fund and its Trustees
with the opportunity to thoughtfully consider and address the matters
proposed before the Fund prepares and mails its proxy statement to
shareholders. Other amendments set forth the procedures, which must be
followed in order for a shareholder to call a special meeting of
shareholders. Please contact the Secretary of the Fund for additional
information about the advance notice requirements or the other amendments to
the by-laws.

On December 16, 2003, the Trustees approved additional changes to the Fund's
by-laws. The auction preferred shares section of the Fund's by-laws was
changed to update the rating agency requirements in keeping with recent
changes to the agencies' basic maintenance reporting requirements for
leveraged closed-end funds. By-laws now require an independent accountant's
confirmation only once per year, at the Fund's fiscal year end, and changes
to the agencies' basic maintenance reporting requirements that include
modifications to the eligible assets and their respective discount factors.
These revisions bring the Fund's by-laws in line with current rating agency

On September 14, 2004, the Trustees approved an amendment to the Fund's
by-laws increasing the maximum applicable dividend rate ceiling on the
preferred shares to conform with the modern calculation methodology used by
the industry and other John Hancock funds.

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 participants' 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 com missions, 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 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

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).
