Dear Fellow Shareholders,

After advancing for a second straight year in 2004, the stock market
pulled back in the first four months of 2005. For much of 2004 the market
had been in the doldrums as investors fretted about rising oil prices,
higher interest rates, the war in Iraq and a closely contested
presidential race. But the year ended on a high note with a sharp rally
sparked by a definitive end to the U.S. presidential election and
moderating oil prices.

Investors were brought back down to earth in January, however, as the
market declined in three of the four weeks and produced negative results
for the month in a broad-based move downward. Rising oil prices and
interest rates, and concerns about less robust corporate earnings growth
were among the culprits that kept investors on the sidelines. Investors
began to re-enter the market in February, reversing January's decline. But
as the month progressed into March and April investors again grew
concerned about further spikes in oil prices and rising interest rates. As
a result, the first four months of 2005 ended with the major indexes in
the red. By the end of April, the Dow Jones Industrial Average had
returned -4.81%, the S&P 500 Index returned -4.00%, while the Nasdaq
Composite Index fell by 11.67%. Bonds performed slightly better, managing
to produce positive results, with the Lehman Brothers Aggregate Bond Index
returning 0.87%.

The way the financial markets have been playing out recently 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 objectives.

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.

Sincerely,

/S/ James A. Shepherdson

James A. Shepherdson,
Chief Executive Officer

MANAGEMENT TEAM

MANAGERS'
REPORT

JOHN HANCOCK
Patriot Premium
Dividend Fund II

Dividend-paying securities encountered mixed conditions during the
six-month period ended April 30, 2005. Preferred stocks -- which are the
primary emphasis of John Hancock Patriot Premium Dividend Fund II --
performed reasonably well from the beginning of the period last November
through roughly mid-February 2005. Because preferreds make fixed payments
in the form of dividends, their prices tend to follow those of U.S.
Treasury securities. Despite evidence of a strengthening economy and
additional short-term interest rate hikes by the Federal Reserve Board,
preferred stock prices generally moved higher, mirroring a somewhat
positive tone in the U.S. Treasury market. That rally was based on
investors' confidence that even though the Fed might continue to raise
rates, those rate hikes would be small and measured given the potential
for record high oil prices and higher interest rates themselves to dampen
economic growth. Preferred stocks were further boosted by the combination
of constrained supply and strong demand. Supply was muted, as fewer
companies issued new preferred securities, while others bought back their
outstanding shares. Demand was fueled by investors' appetite for yield,
particularly in light of the fact that changes in the tax code in 2003
helped to make ownership of certain dividend-yielding stocks more
attractive. Investors also viewed the re-election of President George Bush
as a positive for tax-advantaged preferred stocks, because he vowed to
make permanent the 2003 provisions that reduced the tax rate most
individuals pay on many stock dividends.

"Dividend-paying securities
 encountered mixed conditions
 during the six-month period
 ended April 30, 2005."

From about mid-February through early April 2005, preferred stocks
weakened in response to a series of developments that suggested further
interest rate hikes were in the offing. These developments included
record-setting oil prices, stronger-than-expected data on the


2



jobs market and comments from the Fed that it had seen evidence of a
pickup in inflation. Then, from mid April to the end of the period April
30, preferred stocks regained much of their lost ground as Treasury prices
rallied on weaker March employment and retail sales data, as well as
turbulence in the equity markets.

Utility common stocks

Utility common stocks -- the Fund's other main focus -- also seesawed
during the period. They generally lagged the overall stock market in the
fourth quarter of 2004, as investors sought out companies with higher
growth prospects. But utility common stocks held their ground far better
than preferred and many other common-stock groups in the final weeks of
the period. Their resiliency was due to the combination of growing demand
for their tax-advantaged dividends and a perception that utility
companies' financial shape continued to improve.

"The strong demand for tax-
 advantaged preferred holdings
 helped support many of our
 holdings that sported that feature."

Performance

For the six months ended April 30, 2005, John Hancock Patriot Premium
Dividend Fund II returned 6.62% at net asset value and 6.78% 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 4.28% 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 20.75%,
and the broader stock market as measured by the Standard & Poor's 500
Index returned 3.28%.

Tax-advantaged holdings among top performers

The strong demand for tax-advantaged preferred stocks helped support many
of our holdings that sported that feature. A good example was Baltimore
Gas & Electric Co., a regulated electric and gas public utility in central
Maryland. It also benefited from the


3



fact that it carried a high coupon, which helped cushion its price
declines, and the fact that there is a limited supply of this high-quality
holding. Southern Union Co. also enjoyed relatively good performance for
similar reasons. On the flip side, our lower-coupon holdings in Royal Bank
of Scotland, a major commercial bank, proved somewhat disappointing.

Multi-utilities & unregulated power - 23%, the third is Gas utilities -

Consumer finance - 2%, the ninth is Regional banks - 2%, the tenth is
Integrated oil & gas - 1%, the eleventh is Agricultural products - 1% and
the twelfth is All other - 3%.]

Oil and gas-related utility stocks also post strong results

Rising energy prices provided the fuel for improved company profitability
and higher prices for some of our holdings in utility common stocks
involved with oil and gas production. Among the best performers were our
common-stock holdings in Dominion Resources, one of the nation's largest
producers of energy. Other winners in this segment included National Fuel
Gas Co., an integrated natural gas company, and NiSource Inc., which is
engaged in natural gas transmission, storage and distribution, as well as
electric generation, transmission and distribution. Among our preferred
stock holdings in this sector, we had strong performances from Anadarko
Petroleum Corp., Apache Corporation and Devon Energy Corp.

stocks 64%, Common stocks 35%, and Short-term investments & other 1%.]

Outlook

In our view, the Fed probably hasn't yet reached the end of its campaign
to raise short-term interest rates to cool economic growth and potential
inflationary pressures. This could pose periodic short-term challenges for
dividend-producing securities. Over the longer term, however, we're more
upbeat, especially given the fact that we believe a good portion, if not
all, of future

performance...and what's behind the numbers." The first listing is

Resources followed by an up arrow with the phrase "Rising energy prices

interest rate hikes already have been factored into preferred and utility
common stock prices. Furthermore, there are already some tangible signs
that economic growth has cooled as rates have moved higher. The housing
market has started to slow, with adjustable-rate mortgages moving higher
and conventional 30-year mortgages exceeding 6% at times. Higher oil
prices will also probably act as a drag on economic growth, most likely by
reducing consumers' disposable income and raising corporate America's cost
of doing business. Another signal pointing to slack economic growth is the
March retail sales numbers, which were lackluster at best. We believe that
a slower-growth, low-inflationary environment will provide a favorable
backdrop for both preferred and utility common stocks. That, coupled with
what we believe will continue to be a favorable supply and demand
backdrop, could benefit many dividend-paying securities in the months to
come.

"We believe that a slower-growth,
 low-inflationary environment
 will provide a favorable backdrop
 for both preferred and utility
 common stocks."

The Fund normally will invest at least 65% of its managed assets in
securities of companies in the utilities industry. Such an investment
concentration makes the Fund more susceptible than a more broadly
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 Patriot Premium Dividend Fund II (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.

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.

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. For
federal income tax purposes, the Fund has $52,139 of a capital loss
carryforward available, to the extent provided by regulations, to offset
future net realized capital gains. To the extent that such carryforward is
used by the Fund, no capital gain distributions will be made. The loss
carryforward expires as follows: October 31, 2010 -- $30,872 and October
31, 2011 -- $21,267.

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. The Fund may place a security
on a non-accrual status and reduced related investment income by ceasing
current accruals or writing off interest, or dividends receivable when the
collection of income has become doubtful. Foreign income may be subject to
foreign withholding taxes, which are accrued as applicable.

The Fund records distributions to common and preferred shareholders from
net investment


15



income and net realized gains, if any, on the ex-dividend
date. During the year ended October 31, 2004, the tax character of
distributions paid was as follows: ordinary income $13,498,673.

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 0.50% of the
Fund's average weekly net assets and the value attributable to the Dutch
Auction Rate Transferable Securities preferred shares (collectively,
"managed assets"), plus 5.00% of the Fund's weekly gross income. The
Adviser's total fee is limited to a maximum amount equal to 1.00% annually
of the Fund's average weekly managed assets. For the period ended April
30, 2005, the advisory fee incurred did not exceed the maximum advisory
fee allowed.

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 the shareholders. The Fund pays the Adviser a monthly
administration fee at an annual rate of 0.10% of the Fund's average weekly
managed assets. The compensation for the period amounted to $139,737. The
Fund also paid the Adviser the amount of $5 for certain publishing
services, included in the printing fees.

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
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 investments, as well as any unrealized gains or losses. The Deferred
Compensation Plan investments had no impact on the operations of the Fund.

The Fund is listed for trading on the New York Stock Exchange (NYSE) and
has filed with the NYSE its chief executive officer certification
regarding compliance with the NYSE's listing standards. The Fund also
files with the Securities and Exchange Commission the certification of its
chief executive officer and chief accounting officer required by Section
302 of the Sarbanes-Oxley Act.

Dutch Auction Rate
Transferable Securities
preferred shares Series A
and Series B

The Fund issued Dutch Auction Rate Transferable Securities preferred
shares ("DARTS"), 598 shares of Series A and 598 shares of Series B in a
public offering. The underwriting discount was recorded as a reduction of
the capital of common shares. During the year ended October 31, 1990, the
Fund retired 98 shares of DARTS from both Series A and Series B.

Dividends on the DARTS, which accrue daily, are cumulative at a rate that
was established at the offering of the DARTS and has been reset every 49
days thereafter by an auction. Dividend rates on DARTS Series A and B
ranged from 1.79% to 2.40% and from 1.99% to 2.49%, respectively, during
the period ended April 30, 2005. Accrued dividends on DARTS are included
in the value of DARTS on the Fund's Statement of Assets and Liabilities.

The DARTS 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 DARTS 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 DARTS, as defined in the Fund's by-laws.
If the dividends on the DARTS shall remain unpaid in an amount equal to
two full years' dividends, the holders of the DARTS, as a class, have the
right to elect a majority of the Board of Trustees. In general, the
holders of the DARTS and the common shareholders have equal voting rights
of one vote per share, except that the holders of the DARTS, 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 DARTS and common shareholders.

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 April 30, 2005, aggregated $9,611,463 and $6,025,134,
respectively.

The cost of investments owned on April 30, 2005, including short-term
investments, for federal income tax purposes, was $265,030,446. Gross
unrealized appreciation and depreciation of investments aggregated
$29,128,531 and $12,260,307, respectively, resulting in net unrealized
appreciation of $16,868,224. 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.

Investment
objective
and policy

The Fund's investment objective is to provide a high current income
consistent with modest growth of capital for holders of its common shares
of beneficial interest. The Fund will pursue its objective by investing in
a diversified portfolio of dividend paying preferred and common stocks.

The Fund's non-fundamental investment policy, with respect to the quality
of ratings of its portfolio investments, was changed by a vote of the
Fund's Trustees on September 13, 1994. The 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 including the liquidation preference amount of the DARTS plus
borrowings for investment purposes.  The Fund will notify shareholders at
least 60 days prior to any change in this 80% investment policy.

By-laws

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 that they
intend to present at an annual meeting of share- holders, 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 that 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 the following change to the
Fund's by-laws. The auction preferred 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 requirements.

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.


18



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 may elect to have all distributions of dividends
and capital gains reinvested by Mellon Investor Services, as plan agent
for the common shareholders (the "Plan Agent"). Holders of common shares
who do not elect 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 may join the Plan by filling out and mailing an authorization
card, by notifying the Plan Agent by telephone, or by visiting the Plan
Agent's Web site at www.melloninvestor.com. Shareholders must indicate an
election to reinvest all or a portion of dividend payments.  If received
in proper form by the Plan Agent before the record date of a dividend, the
election will be effective with respect to all dividends paid after such
record date. Shareholders whose shares are held in the name of a broker or
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. In each
case, 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 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.


19



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 noncertificated 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).

ITEM 2.  CODE OF ETHICS.

As of the end of the period, April 30, 2005, the registrant has adopted a
code of ethics, as defined in Item 2 of Form N-CSR, that applies to its

funds.  This was replaced by post-trade reporting and a 30 day hold
requirement for all employees.

supervisors by any access person trading in a personal position worth
$100,000 or more.

controls and procedures as conducted within 90 days of the filing date of
this Form N-CSR, the registrant's principal executive officer and principal
financial officer have concluded that those disclosure controls and
procedures provide reasonable assurance that the material information
required to be disclosed by the registrant on this report is recorded,
processed, summarized and reported within the time periods specified in the
Securities and Exchange Commission's rules and forms.

(b) There were no changes in the registrant's internal control over

an annual report) that have materially affected, or are reasonably likely
to materially affect, the registrant's internal control over financial
