TO OUR SHAREHOLDERS:


For the year ended March 31, 2003, CMA New York Municipal Money Fund
paid shareholders a net annualized yield of .91%.* As of March 31,
2003, the Fund's 7-day yield was .71%.


Economic Environment
For the six-month period ended March 31, 2003, the New York State
economy continued to be significantly affected by the national
economic slowdown, the bursting of the stock market bubble and the
lingering effects of September 11, 2001. The state's retail and
manufacturing sectors showed minimal growth as lower consumer
confidence levels and rising unemployment weighed on consumer
sentiment. New York's economy has become increasingly dependent on
the banking and financial services sector, and the massive layoffs
and corporate downsizing of the last three years have negatively
impacted tax revenues. In fiscal year 2002, state personal income
tax collections declined 3.3% and are estimated to decline by
another 10.4% for fiscal year 2003. The New York State unemployment
rate in February 2003 stood at 6.3% compared to the national average
of 5.8%. The state is currently expecting larger budget gaps in the
coming months as reserves have been drawn down to balance the
current fiscal year. The state estimates that the budget gap for
fiscal year 2003 is approximately $2.2 billion and for fiscal year
2004 is fore cast at $9.3 billion. During fiscal year 2002, the
state's net tax-supported debt level reached $38.8 billion, the
highest among the states, yielding a debt per capita of $2,045,
ranking New York fifth among the states. This high debt level,
combined with the state's depleted reserves, leaves the state
fiscally vulnerable to future economic problems.


*Based on a constant investment throughout the period, with
dividends compounded daily, and reflecting a net return to the
investor after all expenses.


Investment Strategy
Throughout the course of the fiscal year, we continued to maintain a
very high percentage of fixed rate notes as we anticipated falling
interest rates and a sluggish economy. We also maintained very large
positions in tax-exempt commercial paper, which we used to extend
the Fund's maturity. However, we reduced that position during the
last quarter as the short-term tax-exempt yield curve flattened. We
used these instruments to keep the Fund's average maturity in the
45-day - 70-day range.

With an increased short-term tax-exempt supply and expected outflows
from money funds associated with tax season, we will adopt a more
neutral position since we anticipate that the Federal Reserve Board
will leave interest rates unchanged until the end of the war with
Iraq when the state of the economy can be better gauged. We will
look to extend the Fund's average maturity if attractive yield
levels become available and the Federal Reserve Board maintains its
status quo on short-term interest rates. We continue to work closely
with our credit department to maintain the highest quality portfolio
possible. Diversity and credit quality remain important, and we will
continue to closely monitor the ever-changing marketplace.


In Conclusion
We thank you for your support of CMA New York Municipal Money Fund,
and we look forward to serving your investment needs in the months
and years ahead.


Sincerely,



(Terry K. Glenn)

CMA NEW YORK MUNICIPAL MONEY FUND
NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies:
CMA New York Municipal Money Fund (the "Fund") is part of CMA Multi-
State Municipal Series Trust (the "Trust"). The Fund is registered
under the Investment Company Act of 1940 as a non-diversified, open-
end management investment company. The Fund's financial statements
are prepared in conformity with accounting principles generally
accepted in the United States of America, which may require the use
of management accruals and estimates. The following is a summary of
significant accounting policies followed by the Fund.

(a) Valuation of investments--Investments are valued at amortized
cost, which approximates market value. For the purpose of valuation,
the maturity of a variable rate demand instrument is deemed to be
the demand notice payment period. In the case of a floating rate
instrument, the remaining maturity is the next coupon date on which
the interest rate is to be adjusted.

(b) Income taxes--It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute substantially all of its
taxable income to its shareholders. Therefore, no Federal income tax
provision is required.

(c) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Realized gains and losses on security
transactions are determined on the identified cost basis. Interest
income (including amortization of premium and discount) is
recognized on the accrual basis.

(d) Prepaid registration fees--Prepaid registration fees are charged
to expense as the related shares are issued.

(e) Dividends and distributions to shareholders--The Fund declares
dividends daily and reinvests daily such dividends (net of non-
resident alien tax and backup withholding tax withheld) in
additional fund shares at net asset value. Dividends are declared
from the total of net investment income, excluding discounts earned
other than original issue discounts. Net realized capital gains, if
any, are normally distributed annually after deducting prior years'
loss carryforward. The Fund may distribute capital gains more
frequently than annually in order to maintain the Fund's net asset
value at $1.00 per share.

(f) Expenses--Certain expenses have been allocated to the individual
Funds in the Trust on a pro rata basis based upon the respective
aggregate net asset value of each Fund included in the Trust.

(g) Reclassification--Accounting principles generally accepted in
the United States of America require that certain components of net
assets be adjusted to reflect permanent differences between
financial and tax reporting. Accordingly, the current year's
permanent book/tax difference of $164,202 has been reclassified
between paid-in capital in excess of par and accumulated capital
losses. This reclassification has no effect on net assets or net
asset value per share.


2. Investment Advisory Agreement and Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect, wholly-owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the
limited partner.



CMA NEW YORK MUNICIPAL MONEY FUND
NOTES TO FINANCIAL STATEMENTS (CONCLUDED)


FAM is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of the Fund. For such
services, the Fund pays a monthly fee based upon the average daily
value of the Fund's net assets, at the following annual rates: .50%
of the first $500 million of average daily net assets; .425% of
average daily net assets in excess of $500 million but not exceeding
$1 billion; and .375% of average daily net assets in excess of
$1 billion.

Pursuant to the Distribution and Shareholder Servicing Plan in
compliance with Rule 12b-1 under the Investment Company Act of 1940,
Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S")
receives a distribution fee from the Fund at the end of each month
at the annual rate of .125% of average daily net assets of the Fund.
The distribution fee is to compensate MLPF&S financial advisors and
other directly involved branch office personnel for selling shares
of the Fund and for providing direct personal services to
shareholders. The distribution fee is not compensation for the
administrative and operational services rendered to the Fund by
MLPF&S in processing share orders and administering shareholder
accounts.

Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of
ML & Co., is the Fund's transfer agent.

For the year ended March 31, 2003, the Fund reimbursed FAM $46,990
for certain accounting services.

Certain officers and/or trustees of the Fund are officers and/or
directors of FAM, PSI, FDS, and/or ML & Co.


3. Shares of Beneficial Interest:
The number of shares sold, reinvested and redeemed during the
periods corresponds to the amounts included in the Statements of
Changes in Net Assets for net proceeds from sale of shares, value of
shares reinvested and cost of shares redeemed, respectively, since
shares are recorded at $1.00 per share.

4. Distributions to Shareholders:
The tax character of distributions paid during the fiscal years
ended March 31, 2003 and March 31, 2002 was as follows:


                                      3/31/2003          3/31/2002

Distributions paid from:
   Tax-exempt income                 $23,422,927        $43,583,656
                                     -----------        -----------
Total distributions                  $23,422,927        $43,583,656
                                     ===========        ===========



As of March 31, 2003, there were no significant differences between
the book and tax components of net assets.


5. Capital Loss Carryforward:
At March 31, 2003, the Fund had a net capital loss carryforward of
approximately $40,440 of which $2,167 expires in 2004, $11,313
expires in 2006 and $26,960 expires in 2009. This amount will be
available to offset like amounts of any future taxable gains.

confirmation of securities owned as of March 31, 2003, by
correspondence with the custodian and brokers; where replies were
not received from brokers, we performed other auditing procedures.
An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights
referred to above present fairly, in all material respects, the
financial position of CMA New York Municipal Money Fund as of March
31, 2003, the results of its operations for the year then ended, the
changes in its net assets for each of the two years in the period
then ended, and its financial highlights for each of the five years
in the period then ended, in conformity with accounting principles
generally accepted in the United States of America.
