TO OUR SHAREHOLDERS:

For the six-month period ended September 30, 1997, CMA New York 
Municipal Money Fund paid shareholders a net annualized yield of 3.09%*. 
As of September 30, 1997, the Fund's 7-day yield was 3.29%.

Economic Environment and Investment Strategy
During the six-month period ended September 30, 1997, New York State's 
general obligation debt was upgraded by Standard & Poor's Corporation 
for the first time in a decade to A from A-. The state's strong tax 
revenue performance was partly the result of a vibrant US economy and 
record profits on Wall Street. These factors boosted the state's 
finances at the same time New York cut its spending, which it has been 
concentrating on over the last two years. New York state's tax revenues 
rose approximately 12% this year to $33.6 billion from about $30 
billion last year. The state projects tax revenues in excess of $35 
billion next year. The rating upgrade comes at a good time for the 
state, since in November New York voters will decide on a school funding 
plan that could mean the sale of as much as $2.4 billion in bonds for 
new school construction and expanded school programs.

During the six-month period, New York State lawmakers finally approved a 
$67 billion budget, ending the longest state budget stalemate in US 
history. Governor Pataki and the state legislature agreed to tax cuts of 
about $4.75 billion over five years. Lawmakers also cleared Governor 
Pataki's plan to build a 1,500 bed maximum security prison in Altamont, 
New York, as well as two other medium security prisons at locations to 
be determined later.

During the six-month period ended September 30, 1997, new issuance of 
short-term New York debt totaled approximately $4.0 billion, a decrease 
of approximately 5% from the $4.2 billion in debt issued in the six 
months ended March 31, 1997. During October, New York City will come to 
market with approximately $1.7 billion in tax and revenue anticipation 
notes. During the six-month period, net assets of CMA New York Municipal 
Money Fund ranged between $1.1 billion--$1.4 billion, closing the period 
on September 30, 1997, at approximately $1.3 billion. 

As we had discussed in our March 31, 1997 letter to shareholders, we had 
intended to maintain an average portfolio maturity in the range of 45 
days -- 60 days until economic growth slowed and the Federal Reserve 
Board was satisfied with a benign inflationary outlook. We anticipated 
writing our large positions of tax-exempt commercial paper to mature in 
the one-month -- three-month range and allowing our June fixed-rate 
notes to mature. However, the combination of tax time outflows, heavy 
variable rate note issuance and concerns over the elimination of the 
corporate "Deiminimus" clause, whereby corporations could invest up to 
2% of net assets in tax deferred bonds, caused the Fund to underperform 
in April, May and June as variable rate demand notes outperformed fixed-
rate notes and tax-exempt commercial paper. 

As the Fund's commercial paper holdings matured in June, we had the 
opportunity to extend the Fund's maturity at attractive levels. These 
extensions, combined with the economy slowing in the second and third 
quarters of 1997, caused the Fund to outperform the industry average of 
similar short-term New York tax-exempt funds in the last three months of 
the period as interest rates declined. We will continue to maintain the 
Fund's average portfolio maturity in the 45-day -- 60-day range with a 
greater weighting in variable rate demand notes and tax-exempt 
commercial paper instead of fixed-rate notes until the direction of 
interest rates can be ascertained.

Diversification and credit quality remain paramount to the Fund, and we 
will continue to closely monitor the everchanging 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 future.

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. These unaudited financial statements 
reflect all adjustments which are, in the opinion of management, 
necessary to a fair statement of the results for the interim period 
presented. All such adjustments are of a normal recurring nature. 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 next 
coupon date on which the interest rate is to be adjusted. In the case of 
a floating rate instrument, the remaining maturity is the demand notice 
payment period.

(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). Interest income (including amortization of premium and discount) 
is recognized on the accrual basis. Realized gains and losses on 
security transactions are determined on the identified cost basis.

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

(e) Dividends and distributions to share-holders -- The Fund declares 
dividends daily and reinvests daily such dividends (net of non-resident 
alien tax and back-up 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.

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.

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: 0.50% of the 
first $500 million of average daily net assets; 0.425% of average daily 
net assets in excess of $500 million but not exceeding $1 billion; and 
0.375% 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 Inc. ("MLPF&S") receives a 
distribution fee from the Fund at the end of each month at the annual 
rate of 0.125% of average daily net assets of the Fund. The distribution 
fee is to compensate MLPF&S financial consultants 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.

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

Accounting services are provided to the Fund by FAM at cost.

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

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

4. Capital Loss Carryforward:
At March 31, 1997, the Fund had a net capital loss carryforward of 
approximately $883,000, of which $81,000 expires in 1998, $203,000 
expires in 2001, $293,000 expires in 2002, $304,000 expires in 2003 and 
$2,000 expires in 2004. This amount will be available to offset like 
amounts of any future taxable gains.
