MuniYield California
Fund, Inc.


Semi-Annual Report
April 30, 2004



MuniYield California Fund, Inc. seeks to provide shareholders with
as high a level of current income exempt from Federal and California
income taxes as is consistent with its investment policies and
prudent investment management by investing primarily in a portfolio
of long-term municipal obligations the interest on which, in the
opinion of bond counsel to the issuer, is exempt from Federal and
California income taxes.

This report, including the financial information herein, is
transmitted to shareholders of MuniYield California Fund, Inc. for
their information. It is not a prospectus. Past performance results
shown in this report should not be considered a representation of
future performance. The Fund has leveraged its Common Stock and
intends to remain leveraged by issuing Preferred Stock to provide
the Common Stock shareholders with a potentially higher rate of
return. Leverage creates risks for Common Stock shareholders,
including the likelihood of greater volatility of net asset value
and market price of shares of the Common Stock, and the risk that
fluctuations in the short-term dividend rates of the Preferred Stock
may affect the yield to Common Stock shareholders. Statements and
other information herein are as dated and are subject to change.

The Benefits and Risks of Leveraging


MuniYield California Fund, Inc. utilizes leveraging to seek
to enhance the yield and net asset value of its Common Stock.
However, these objectives cannot be achieved in all interest rate
environments. To leverage, the Fund issues Preferred Stock, which
pays dividends at prevailing short-term interest rates, and invests
the proceeds in long-term municipal bonds. The interest earned on
these investments, net of dividends to Preferred Stock, is paid to
Common Stock shareholders in the form of dividends, and the value of
these portfolio holdings is reflected in the per share net asset
value of the Fund's Common Stock. However, in order to benefit
Common Stock shareholders, the yield curve must be positively
sloped; that is, short-term interest rates must be lower than long-
term interest rates. At the same time, a period of generally
declining interest rates will benefit Common Stock shareholders. If
either of these conditions change, then the risks of leveraging will
begin to outweigh the benefits.

To illustrate these concepts, assume a fund's Common Stock
capitalization of $100 million and the issuance of Preferred
Stock for an additional $50 million, creating a total value of
$150 million available for investment in long-term municipal bonds.
If prevailing short-term interest rates are approximately 3% and
long-term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million
of Preferred Stock based on the lower short-term interest rates. At
the same time, the fund's total portfolio of $150 million earns the
income based on long-term interest rates. Of course, increases in
short-term interest rates would reduce (and even eliminate) the
dividends on the Common Stock.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term
investments, and therefore the Common Stock shareholders are the
beneficiaries of the incremental yield. However, if short-term
interest rates rise, narrowing the differential between short-term
and long-term interest rates, the incremental yield pickup on the
Common Stock will be reduced or eliminated completely. At the same
time, the market value of the fund's Common Stock (that is, its
price as listed on the New York Stock Exchange) may, as a result,
decline. Furthermore, if long-term interest rates rise, the Common
Stock's net asset value will reflect the full decline in the price
of the portfolio's investments, since the value of the fund's
Preferred Stock does not fluctuate. In addition to the decline in
net asset value, the market value of the fund's Common Stock may
also decline.

As a part of its investment strategy, the Fund may invest in certain
securities whose potential income return is inversely related to
changes in a floating interest rate ("inverse floaters"). In
general, income on inverse floaters will decrease when short-term
interest rates increase and increase when short-term interest rates
decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of
reduced or eliminated interest payments and losses of invested
principal. In addition, inverse floaters have the effect of
providing investment leverage and, as a result, the market value of
such securities will generally be more volatile than that of fixed-
rate, tax-exempt securities. To the extent the Fund invests in
inverse floaters, the market value of the Fund's portfolio and the
net asset value of the Fund's shares may also be more volatile than
if the Fund did not invest in such securities. As of April 30, 2004,
the percentage of the Fund's total net assets invested in inverse
floaters was 9.88%.


Swap Agreements


The Fund may also invest in swap agreements, which are over-the-
counter contracts in which one party agrees to make periodic
payments based on the change in market value of a specified bond,
basket of bonds, or index in return for periodic payments based on a
fixed or variable interest rate or the change in market value of a
different bond, basket of bonds or index. Swap agreements may be
used to obtain exposure to a bond or market without owning or taking
physical custody of securities.

A Letter From the President


Dear Shareholder

For the six-month and 12-month periods ended April 30, 2004, the
Lehman Brothers Municipal Bond Index posted returns of +1.19% and
+2.68%, respectively. Its taxable counterpart, the Lehman Brothers
Aggregate Bond Index, had returns of +1.25% and +1.82% for the same
periods. Amid considerable month-to-month volatility, tax-exempt
bond yields rose over the past year, although not to the same extent
as 10-year U.S. Treasury yields. In all, tax-exempt securities
continued to be an attractive fixed income investment alternative.

As of April month-end, the Federal Reserve Board maintained its
accommodative policy stance, although a better-than-expected
employment report for the month of March prompted speculation that
an interest rate increase could come sooner than many had expected.
On April 2, 2004, the good news on the employment front - previously
the one dim spot in an otherwise bright economic picture - helped
prompt the yield on the 10-year Treasury bond to spike nearly 25
basis points (.25%) from 3.91% to 4.15%. Market watchers continue to
monitor the economic data and Federal Reserve Board language for
indications of interest rate direction. If economic growth maintains
its recent pace and employment figures continue to improve, many
believe it is just a matter of time before interest rates move
upward.

Equity markets, in the meantime, gleaned support from the improving
economic environment and provided attractive returns. For the
six-month and 12-month periods ended April 30, 2004, the Standard &
Poor's 500 Index returned +6.27% and +22.88%, respectively.
Significant fiscal and monetary stimulus in 2003, including low
interest rates and tax cuts, has opened the door to consumer
spending, capital spending, increases in exports and long-awaited
job growth. As expected, these developments have led the way to
improvements in corporate earnings - a positive for stock markets.

The events and efforts of the past year leave us with a much
stronger economy today. Of course, markets will always fluctuate,
and there are many uncertainties - not the least of which are
geopolitical in nature - which can translate into negative market
movements. Keeping this in mind, we encourage you to revisit your
portfolio and your asset allocation strategy to ensure you are well
positioned to take advantage of the opportunities that lie ahead.
Importantly, your financial advisor can help you develop a strategy
most suitable for your circumstances through all types of market and
economic cycles.

We thank you for trusting Merrill Lynch Investment Managers with
your investment assets, and we look forward to serving you in the
months and years ahead.



Sincerely,



(Terry K. Glenn)

A Discussion With Your Fund's Portfolio Manager


Given the still uncertain interest rate environment, we maintained a
defensive stance throughout the period, seeking to protect the
Fund's net asset value and enhance current yield for our
shareholders.


Describe the recent market environment relative to municipal bonds.

For much of the six-month period, a positive economic backdrop
helped bond prices to move higher as yields, which typically move
opposite of prices, declined. In early April, however, a
surprisingly strong monthly employment report triggered fears that
the long-accommodative Federal Reserve Board might raise interest
rates sooner than many had expected. As a result, bond yields rose
(prices fell) sharply for the remainder of the period. At the end of
April, long-term U.S. Treasury bond yields had climbed to 5.13%,
representing an increase of approximately 15 basis points (.15%)
over the past six months. Ten-year U.S. Treasury note yields stood
at 4.30% as of period-end, an increase of more than 20 basis points.

Tax-exempt bond yields generally mimicked the movement of their
taxable counterparts, although volatility in the municipal market
was more subdued. Long-term revenue bond yields, as measured by the
Bond Buyer Revenue Bond Index, rose just four basis points over the
past six months. For the same period, yields on AAA-rated issues
maturing in 30 years increased approximately 10 basis points to
4.93% while yields on 10-year, AAA-rated issues rose more than
16 basis points to nearly 4%, according to Municipal Market Data.
The more marked increase in 10-year bond yields may be attributed to
the fact that recent issuance has been heavily concentrated in the
10-year - 20-year range. The resulting supply imbalance prompted
higher intermediate bond yields (and lower prices). Longer-maturity
and lower-rated issues continued to benefit from more favorable
supply/demand factors and, therefore, have seen less price
depreciation. For the six-month period as a whole, municipal bond
supply declined approximately 5% compared to the same period a year
ago.

While investor enthusiasm for stocks has taken some attention away
from fixed income markets, overall demand for tax-exempt municipal
bonds has remained positive. Recent Federal Reserve Board statistics
showed that U.S. household holdings of municipal securities
increased by more than $25 billion during the fourth quarter of 2003
to approximately $680 billion. In addition, data from the Investment
Company Institute indicates that, in just the first three months of
2004, tax-exempt bond funds have seen net new cash flows of almost
$640 million.


Describe conditions in the State of California.

In March 2004, California voters approved measures authorizing the
issuance of up to $15 billion in economic recovery bonds to finance
accumulated fiscal-year deficits. At the same time, the State
Constitution was amended to provide for the enactment and
maintenance of a balanced state budget; the establishment of
specific reserve requirements; and restrictions on future
deficit-related borrowing. Passage of the propositions mitigated
short-term liquidity risks while providing the Legislature with
additional time to formulate future budget solutions.

Following the approval of these measures, Moody's Investors Service
revised the state's credit outlook from negative to stable
while Standard & Poor's (S&P) revised the outlook from stable to
positive. Moody's and S&P affirmed California's outstanding long-
term ratings of Baa1 and BBB, respectively, noting that further
credit improvement is contingent on the state's ability to reduce
its structural imbalances. The positive developments came as a
welcomed change following several months of negative news,
highlighted by a $38 billion budget deficit, a gubernatorial recall
election in October 2003 and credit downgrades from all three major
rating agencies.


How did the Fund perform in light of the existing market conditions?

For the six-month period ended April 30, 2004, the Common Stock of
MuniYield California Fund, Inc. had net annualized yields of 6.56%
and 7.14%, based on a period-end per share net asset value of $14.85
and a per share market price of $13.66, respectively, and $.486 per
share income dividends. Over the same period, the total investment
return on the Fund's Common Stock was +1.22%, based on a change in
per share net asset value from $15.17 to $14.85, and assuming
reinvestment of $.486 per share ordinary income dividends.

For the six-month period ended April 30, 2004, the Fund's Auction
Market Preferred Stock (AMPS) had an average yield of 1.03% for
Series A, .92% for Series B and .81% for Series C.



MUNIYIELD CALIFORNIA FUND, INC., APRIL 30, 2004



The Fund's total return, based on net asset value, lagged its
comparable Lipper category of California Municipal Debt Funds, which
had an average return of +2.41% for the six-month period. (Funds in
this Lipper category invest primarily in municipal debt issues
exempt from taxation in the State of California.) We have been
managing the Fund conservatively, maintaining a shorter duration
than many of our peers in order to protect the Fund's net asset
value and insulate the portfolio from any spikes in interest rates.
During the past six months, the municipal bond market rallied
(yields fell as prices rose) more strongly than anticipated, and our
strategy temporarily resulted in under-performance relative to our
peers. We continue to believe the Fund is positioned to outperform
when interest rates eventually rise, a phenomenon we began to see as
the period closed.

For a description of the Fund's total investment return based on a
change in the per share market value of the Fund's Common Stock (as
measured by the trading price of the Fund's shares on the New York
Stock Exchange), and assuming reinvestment of dividends, please
refer to the Financial Highlights section included in this report.
As a closed-end fund, the Fund's shares may trade in the secondary
market at a premium or discount to the Fund's net asset value. As a
result, total investment returns based on changes in the market
value of the Fund's Common Stock can vary significantly from total
investment return based on changes in the Fund's net asset value.


What changes were made to the portfolio during the period?

We have been managing the Fund defensively - preparing for an
eventual rise in long-term interest rates - for some time. In
keeping with this approach, our portfolio duration has been
substantially below the industry average. Generally, the lower the
duration, the less an investment will fluctuate in value as interest
rates move up or down. Although our emphasis on limiting price
volatility does result in slight underperformance when interest
rates move lower, that trend had already started to reverse
dramatically as the period came to a close. We believe the Fund's
relative performance will improve meaningfully as market rates
continue to rise on expectations that the Federal Reserve Board will
raise the Federal Funds target rate sooner than many had
anticipated.

While seeking to protect the Fund's net asset value, we also have
been emphasizing current yield in the portfolio. To that end, our
primary focus when making purchases has been on higher-coupon bonds
that we believe can deliver a high current accrual.

During the period, the Fund's borrowing costs generally remained in
the .75% - 1.25% range. These attractive funding levels, in
combination with a steep tax-exempt yield curve, generated a
significant income benefit to the Fund's Common Stock shareholders.
At this point, the Federal Reserve Board appears poised to begin
raising short-term interest rates, most likely later in 2004. The
increase, however, is expected to be gradual and should not have a
material impact on the positive advantage leverage has had on the
Fund's Common Stock yield. We expect short-term borrowing costs to
remain near current attractive levels for the coming months.
However, should the spread between short-term and long-term interest
rates narrow, the benefits of leverage will decline, and as a
result, reduce the yield on the Fund's Common Stock. At the end of
the period, the Fund's leverage amount, due to AMPS, was 30.68% of
total assets. (For a more complete explanation of the benefits and
risks of leveraging, see page 2 of this report to shareholders.)


How would you characterize the Fund's position at the close of the
period?

In preparation for rising interest rates, the Fund remained
defensively positioned at period-end with a shorter-than-average
portfolio duration. The Fund also was fully invested at the close of
the period. With short-term cash equivalents yielding only about 1%,
the performance penalty for holding assets in cash reserves is far
too severe.

While we are keeping an eye toward adopting a more aggressive
stance, we believe such a move is further down the road, perhaps
after the Federal Reserve Board has entered a tightening monetary
cycle. As interest rates rise, we also intend to address the Fund's
call structure. If the market falls far enough, in our estimation,
it may be time to extend the average call protection in the Fund,
effectively making it a more aggressive portfolio.

Finally, credit quality remains an important focus in managing the
Fund. Given the recent positive developments in California's
finances, we may look to increase the Fund's exposure to state-
related credits; that is, California general obligation bonds and
other direct obligations backed by the full faith and credit of the
state.

Notes to Financial Statements


1. Significant Accounting Policies:
MuniYield California Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940, as amended, as a non-diversified,
closed-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. Actual results
may differ from these estimates. 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 Fund determines and makes available for
publication the net asset value of its Common Stock on a weekly
basis. The Fund's Common Stock is listed on the New York Stock
Exchange under the symbol MYC. The following is a summary of
significant accounting policies followed by the Fund.

(a) Valuation of investments--Municipal bonds are traded primarily
in the over-the-counter markets and are valued at the last available
bid price in the over-the-counter market or on the basis of yield
equivalents as obtained by the Fund's pricing service from one or
more dealers that make markets in such securities. Financial futures
contracts and options thereon, which are traded on exchanges, are
valued at their closing prices as of the close of such exchanges.
Options written or purchased are valued at the last sale price in
the case of exchange-traded options. In the case of options traded
in the over-the-counter market, valuation is the last asked price
(options written) or the last bid price (options purchased). Swap
agreements are valued by quoted fair values received daily by the
Fund from the counterparty. Short-term investments with a remaining
maturity of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market
quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Board of
Directors of the Fund, including valuations furnished by a pricing
service retained by the Fund, which may utilize a matrix system for
valuations. The procedures of the pricing service and its valuations
are reviewed by the officers of the Fund under the general
supervision of the Board of Directors.

(b) Derivative financial instruments--The Fund may engage in various
portfolio investment strategies both to increase the return of the
Fund and to hedge, or protect, its exposure to interest rate
movements and movements in the securities markets. Losses may arise
due to changes in the value of the contract or if the counterparty
does not perform under the contract.

* Financial futures contracts--The Fund may purchase or sell
financial futures contracts and options on such futures contracts.
Futures contracts are contracts for delayed delivery of securities
at a specific future date and at a specific price or yield. Upon
entering into a contract, the Fund deposits and maintains as
collateral such initial margin as required by the exchange on which
the transaction is effected. Pursuant to the contract, the Fund
agrees to receive from or pay to the broker an amount of cash equal
to the daily fluctuation in value of the contract. Such receipts or
payments are known as variation margin and are recorded by the Fund
as unrealized gains or losses. When the contract is closed, the Fund
records a realized gain or loss equal to the difference between the
value of the contract at the time it was opened and the value at the
time it was closed.

* Options--The Fund may write covered call options and purchase put
options. When the Fund writes an option, an amount equal to the
premium received by the Fund is reflected as an asset and an
equivalent liability. The amount of the liability is subsequently
marked to market to reflect the current market value of the option
written. When a security is purchased or sold through an exercise of
an option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.



MUNIYIELD CALIFORNIA FUND, INC., APRIL 30, 2004



Notes to Financial Statements (continued)


* Forward interest rate swaps--The Fund may enter into forward
interest rate swaps. In a forward interest rate swap, the Fund and
the counterparty agree to make periodic net payments on a specified
notional contract amount, commencing on a specified future effective
date, unless terminated earlier. When the agreement is closed, the
Fund records a realized gain or loss in an amount equal to the value
of the agreement.

(c) 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.

(d) 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 is recognized on the accrual basis. Dividend income is
recorded on the ex-dividend dates. The Fund amortizes all premiums
and discounts on debt securities.

(e) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates.

Dividend Policy


The Fund's dividend policy is to distribute all or a portion of its
net investment income to its shareholders on a monthly basis. In
order to provide shareholders with a more stable level of dividend
distributions, the Fund may at times pay out less than the entire
amount of net investment income earned in any particular month and
may at times in any particular month pay out such accumulated but
undistributed income in addition to net investment income earned in
that month. As a result, the dividends paid by the Fund for any
particular month may be more or less than the amount of net
investment income earned by the Fund during such month. The Fund's
current accumulated but undistributed net investment income, if any,
is disclosed in the Statement of Net Assets, which comprises part of
the financial information included in this report.
