GAMCO International Growth Fund, Inc.

Annual Report
December 31, 2009

Caesar Bryan

To Our Shareholders,

     The Sarbanes-Oxley Act requires a fund’s principal executive and financial officers to certify the entire contents of the semi-annual and annual shareholder reports in a filing with the Securities and Exchange Commission (“SEC”) on Form N-CSR. This certification would cover the portfolio manager’s commentary and subjective opinions if they are attached to or a part of the financial statements. Many of these comments and opinions would be difficult or impossible to certify.

     Because we do not want our portfolio managers to eliminate their opinions and/or restrict their commentary to historical facts, we have separated their commentary from the financial statements and investment portfolio and have sent it to you separately. Both the commentary and the financial statements, including the portfolio of investments, will be available on our website at www.gabelli.com/funds.

     Enclosed are the audited financial statements including the investment portfolio as of December 31, 2009 with a description of factors that affected the performance during the past year.

Performance Discussion (Unaudited)

     In 2009 the GAMCO International Growth Fund (the “Fund”) (Class AAA) net asset value (“NAV”) per share rose 38.02% compared with gains of 41.59% for the Lipper International Multi-Cap Growth Fund Average and 32.46% for the Morgan Stanley Capital International (“MSCI”) Europe, Australasia, and the Far East (“EAFE”) Index.

     MSCI data (all returns in dollars) shows 15 of 23 major national indices advanced in the fourth quarter. The U.S. (+5.9%) was one of the better performers during the quarter, which marked a change from the third quarter where strength in most other countries made the U.S. a relative laggard. The best performing country was Norway (+14.9%), followed by Singapore (+9.8%), the United Kingdom (+7.0%), Canada (+5.0%), Australia (+4.9%), Switzerland (+3.8%), the Netherlands (+3.7%), Hong Kong and Sweden (+3.6%), Germany (+2.2%), France (+2.1%), Belgium (+1.6%), Spain (+1.3%), and Portugal (+0.4%). Fourth quarter laggards were led by Greece (-22.4%), followed by Austria (-9.8%), Finland (-3.5%), Denmark and Japan (-2.8%), and Ireland and Italy (-2.7%). New Zealand was unchanged during the quarter. In emerging markets, eighteen of twenty-two countries recorded positive performance in the fourth quarter. Of the four largest emerging markets, Brazil (+12.1%) posted the best quarterly performance, followed by Russia (+10.4%), China (+9.5%), and India (+7.5%).

     Xstrata, the Fund’s largest holding (4.5% of net assets as of December 31, 2009) contributed to the Fund’s positive performance in 2009. Xstrata is a diversified mining group which focuses on seven international commodity markets: copper, coking coal, thermal coal, ferrochrome, nickel, vanadium, and zinc, with additional exposures to platinum group metals, gold, cobalt, lead, and silver, recycling facilities, and a suite of global technology products. Additional selected holdings that contributed to the Fund’s positive performance for the year were Rio Tinto (3.7%), Petroleo Brasileiro (3.3%), which is Brazil’s largest energy company with a presence in twenty-seven countries, Anglo American (3.1%), and Technip (1.0%). Some of our weaker performing stocks during the year were Imperial Oil Ltd. (1.7%), Square Enix Holdings Co. (1.2%), Harmony Gold Mining Co. (1.0%), and Takeda Pharmaceutical Co. Ltd. (0.7%).

Sincerely yours,

In the current prospectus, the expense ratios for Class AAA, A, B, C, and I Shares are 2.01%, 2.01%, 2.76%, 2.76%, and 1.76%, respectively. See page 10 for the expense ratios for the year ended December 31, 2009. Class AAA and Class I Shares do not have a sales charge. The maximum sales charge for Class A, B, and C Shares is 5.75%, 5.00%, and 1.00%, respectively.

(a)	Returns represent past performance and do not guarantee future results. Total returns and average annual returns reflect changes in share price and reinvestment of distributions and are net of expenses. Investment returns and the principal value of an investment will fluctuate. When shares are redeemed, they may be worth more or less than their original cost. Performance returns for periods of less than one year are not annualized. Current performance may be lower or higher than the performance data presented. Visit www.gabelli.com for performance information as of the most recent month end. Investors should carefully consider the investment objectives, risks, charges, and expenses of the Fund before investing. The prospectus contains more information about this and other matters and should be read carefully before investing.
	Investing in foreign securities involves risks not ordinarily associated with investments in domestic issues, including currency fluctuation, economic, and political risks. The Class AAA Shares NAVs per share are used to calculate performance for the periods prior to the issuance of Class A Shares, Class B Shares, Class C Shares, and Class I Shares on July 25, 2001, January 17, 2001, December 17, 2000, and January 11, 2008, respectively. The actual performance of the Class B Shares and Class C Shares would have been lower due to the additional expenses associated with these classes of shares. The actual performance of the Class I Shares would have been higher due to lower expenses related to this class of shares. The Morgan Stanley Capital International (“MSCI”) Europe, Australasia, and the Far East (“EAFE”) Index is an unmanaged indicator of international stock market performance, while the Lipper International Multi-Cap Growth Fund Average reflects the average performance of mutual funds classified in this particular category. Dividends are considered reinvested. You cannot invest directly in an index.
(b)	Includes the effect of the maximum 5.75% sales charge at the beginning of the period.
(c)	Performance results include the deferred sales charges for the Class B Shares upon redemption at the end of the quarter, one year, three year, and five year periods of 5%, 5%, 3%, and 2%, respectively, of the Fund’s NAV per share at the time of purchase or sale, whichever is lower. Class B Shares are not available for new purchases.
(d)	Performance results include the deferred sales charges for the Class C Shares upon redemption at the end of the quarter and one year periods of 1% of the Fund’s NAV per share at the time of purchase or sale, whichever is lower.

GAMCO International Growth Fund, Inc.
Disclosure of Fund Expenses (Unaudited)
For the Six Month Period from July 1, 2009 through December 31, 2009 Expense Table

We believe it is important for you to understand the impact of fees and expenses regarding your investment. All mutual funds have operating expenses. As a shareholder of a fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund’s gross income, directly reduce the investment return of a fund. When a fund’s expenses are expressed as a percentage of its average net assets, this figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your Fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period.

The Expense Table below illustrates your Fund’s costs in two ways:

Actual Fund Return: This section provides information about actual account values and actual expenses. You may use this section to help you to estimate the actual expenses that you paid over the period after any fee waivers and expense reimbursements. The “Ending Account Value” shown is derived from the Fund’s actual return during the past six months, and the “Expenses Paid During Period” shows the dollar amount that would have been paid by an investor who started with $1,000 in the Fund.You may use this information, together with the amount you invested, to estimate the expenses that you paid over the period.

To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your Fund under the heading “Expenses Paid During Period” to estimate the expenses you paid during this period.

Hypothetical 5% Return: This section provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio. It assumes a hypothetical annualized return of 5% before expenses during the period shown. In this case — because the hypothetical return used is not the Fund’s actual return — the results do not apply to your investment and you cannot use the hypothetical account value and expense to estimate the actual ending account balance or expenses you paid for the period. This example is useful in making comparisons of the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in shareholder reports of other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs such as sales charges (loads), redemption fees, or exchange fees, if any, which are described in the Prospectus. If these costs were applied to your account, your costs would be higher. Therefore, the 5% hypothetical return is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. The “Annualized Expense Ratio” represents the actual expenses for the last six months and may be different from the expense ratio in the Financial Highlights which is for the year ended December 31, 2009.

* Expenses are equal to the Fund’s annualized expense ratio for the last six months multiplied by the average account value over the period, multiplied by the number of days in the most recent fiscal half-year, then divided by 365.

GAMCO International Growth Fund, Inc.
Notes to Financial Statements

1. Organization. GAMCO International Growth Fund, Inc. (the “Fund”) was organized on May 25, 1994 as a Maryland corporation. The Fund is a diversified open-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund’s primary objective is long-term capital appreciation. The Fund commenced investment operations on June 30, 1995.

2. Significant Accounting Policies. The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) has become the exclusive reference of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the SEC under authority of federal laws are also sources of authoritative GAAP for SEC registrants. The ASC has superseded all existing non-SEC accounting and reporting standards. The Fund’s financial statements are prepared in accordance with GAAP, which may require the use of management estimates and assumptions. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.

Security Valuation. Portfolio securities listed or traded on a nationally recognized securities exchange or traded in the U.S. over-the-counter market for which market quotations are readily available are valued at the last quoted sale price or a market’s official closing price as of the close of business on the day the securities are being valued. If there were no sales that day, the security is valued at the average of the closing bid and asked prices or, if there were no asked prices quoted on that day, then the security is valued at the closing bid price on that day. If no bid or asked prices are quoted on such day, the security is valued at the most recently available price or, if the Board of Directors (the “Board”) so determines, by such other method as the Board shall determine in good faith to reflect its fair market value. Portfolio securities traded on more than one national securities exchange or market are valued according to the broadest and most representative market, as determined by Gabelli Funds, LLC (the “Adviser”).

Portfolio securities primarily traded on a foreign market are generally valued at the preceding closing values of such securities on the relevant market, but may be fair valued pursuant to procedures established by the Board if market conditions change significantly after the close of the foreign market but prior to the close of business on the day the securities are being valued. Debt instruments with remaining maturities of sixty days or less that are not credit impaired are valued at amortized cost, unless the Board determines such amount does not reflect the securities’ fair value, in which case these securities will be fair valued as determined by the Board. Debt instruments having a maturity greater than sixty days for which market quotations are readily available are valued at the average of the latest bid and asked prices. If there were no asked prices quoted on such day, the security is valued using the closing bid price.

Securities and assets for which market quotations are not readily available are fair valued as determined by the Board. Fair valuation methodologies and procedures may include, but are not limited to: analysis and review of available financial and non-financial information about the company; comparisons with the valuation and changes in valuation of similar securities, including a comparison of foreign securities with the equivalent U.S. dollar value ADR securities at the close of the U.S. exchange; and evaluation of any other information that could be indicative of the value of the security.

GAMCO International Growth Fund, Inc.
Notes to Financial Statements (Continued)

The inputs and valuation techniques used to measure fair value of the Fund’s investments are summarized into three levels as described in the hierarchy below:

• Level 1 — quoted prices in active markets for identical securities;

• Level 2 — other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.); and

• Level 3 — significant unobservable inputs (including the Fund’s determinations as to the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The summary of the Fund’s investments by inputs used to value the Fund’s investments as of December 31, 2009 is as follows:

Derivative Financial Instruments.

The Fund may engage in various portfolio investment strategies by investing in a number of derivative financial instruments for the purpose hedging against a specific transaction with respect to either the currency in which the transaction is denominated or another currency. Investing in certain derivative financial instruments, including participation in the options, futures, or swap markets, entails certain execution, liquidity, hedging, tax, and securities, interest, credit, or currency market risks. Losses may arise if the Adviser’s prediction of movements in the direction of the securities, foreign currency, and interest rate markets is inaccurate. Losses may also arise if the counterparty does not perform its duties under a contract, or that, in the event of default, the Fund may be delayed in or prevented from obtaining payments or other contractual remedies owed to it under derivative contracts. The creditworthiness of the counterparties is closely monitored in order to minimize these risks. Participation in derivative transactions involves investment risks, transaction costs, and potential losses to which the Fund would not be subject absent the use of these strategies. The consequences of these risks, transaction costs, and losses may have a negative impact on the Fund’s ability to pay distributions.

     Forward Foreign Exchange Contracts. The Fund may engage in forward foreign exchange contracts for the purpose of hedging a specific transaction with respect to either the currency in which the transaction is denominated or another currency as deemed appropriate by the Adviser. Forward foreign exchange contracts

12

GAMCO International Growth Fund, Inc.
Notes to Financial Statements (Continued)

are valued at the forward rate and are marked-to-market daily. The change in market value is included in unrealized appreciation/depreciation on investments and foreign currency translations. 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.

The use of forward foreign exchange contracts does not eliminate fluctuations in the underlying prices of the Fund’s portfolio securities, but it does establish a rate of exchange that can be achieved in the future. Although forward foreign exchange contracts limit the risk of loss due to a decline in the value of the hedged currency, they also limit any potential gain that might result should the value of the currency increase. In addition, the Fund could be exposed to risks if the counterparties to the contracts are unable to meet the terms of their contracts. During the year ended December 31, 2009, the Fund had no investments in forward foreign exchange contracts.

Repurchase Agreements. The Fund may enter into repurchase agreements with primary government securities dealers recognized by the Federal Reserve Board, with member banks of the Federal Reserve System, or with other brokers or dealers that meet credit guidelines established by the Adviser and reviewed by the Board. Under the terms of a typical repurchase agreement, the Fund takes possession of an underlying debt obligation subject to an obligation of the seller to repurchase, and the Fund to resell, the obligation at an agreed-upon price and time, thereby determining the yield during the Fund’s holding period. It is the policy of the Fund to always receive and maintain securities as collateral whose market value, including accrued interest, is at least equal to 102% of the dollar amount invested by the Fund in each agreement. The Fund will make payment for such securities only upon physical delivery or upon evidence of book entry transfer of the collateral to the account of the custodian. To the extent that any repurchase transaction exceeds one business day, the value of the collateral is marked-to-market on a daily basis to maintain the adequacy of the collateral. If the seller defaults and the value of the collateral declines or if bankruptcy proceedings are commenced with respect to the seller of the security, realization of the collateral by the Fund may be delayed or limited. At December 31, 2009, there were no open repurchase agreements.

Foreign Currency Translations. The books and records of the Fund are maintained in U.S. dollars. Foreign currencies, investments, and other assets and liabilities are translated into U.S. dollars at the current exchange rates. Purchases and sales of investment securities, income, and expenses are translated at the exchange rate prevailing on the respective dates of such transactions. Unrealized gains and losses that result from changes in foreign exchange rates and/or changes in market prices of securities have been included in unrealized appreciation/depreciation on investments and foreign currency translations. Net realized foreign currency gains and losses resulting from changes in exchange rates include foreign currency gains and losses between trade date and settlement date on investment securities transactions, foreign currency transactions, and the difference between the amounts of interest and dividends recorded on the books of the Fund and the amounts actually received. The portion of foreign currency gains and losses related to fluctuation in exchange rates between the initial trade date and subsequent sale trade date is included in realized gain/loss on investments.

Foreign Securities. The Fund may directly purchase securities of foreign issuers. Investing in securities of foreign issuers involves special risks not typically associated with investing in securities of U.S. issuers. The risks include possible revaluation of currencies, the inability to repatriate funds, less complete financial

GAMCO International Growth Fund, Inc.
Notes to Financial Statements (Continued)

information about companies, and possible future adverse political and economic developments. Moreover, securities of many foreign issuers and their markets may be less liquid and their prices more volatile than those of securities of comparable U.S. issuers.

Foreign Taxes. The Fund may be subject to foreign taxes on income, gains on investments, or currency repatriation, a portion of which may be recoverable.The Fund will accrue such taxes and recoveries as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.

Securities Transactions and Investment Income. Securities transactions are accounted for on the trade date with realized gain or loss on investments determined by using the identified cost method. Interest income (including amortization of premium and accretion of discount) is recorded on the accrual basis. Premiums and discounts on debt securities are amortized using the effective yield to maturity method. Dividend income is recorded on the ex-dividend date except for certain dividends which are recorded as soon as the Fund is informed of the dividend.

Determination of Net Asset Value and Calculation of Expenses. Certain administrative expenses are common to, and allocated among, various affiliated funds. Such allocations are made on the basis of each fund’s average net assets or other criteria directly affecting the expenses as determined by the Adviser pursuant to procedures established by the Board.

In calculating the NAV per share of each class, investment income, realized and unrealized gains and losses, redemption fees, and expenses other than class specific expenses are allocated daily to each class of shares based upon the proportion of net assets of each class at the beginning of each day. Distribution expenses are borne solely by the class incurring the expense.

Custodian Fee Credits and Interest Expense. When cash balances are maintained in the custody account, the Fund receives credits which are used to offset custodian fees. The gross expenses paid under the custody arrangement are included in custodian fees in the Statement of Operations with the corresponding expense offset, if any, shown as “custodian fee credits.” When cash balances are overdrawn, the Fund is charged an overdraft fee equal to 2.00% above the federal funds rate on outstanding balances. This amount, if any, would be included in “interest expense” in the Statement of Operations.

Distributions to Shareholders. Distributions to shareholders are recorded on the ex-dividend date. Distributions to shareholders are based on income and capital gains as determined in accordance with federal income tax regulations, which may differ from income and capital gains as determined under U.S. generally accepted accounting principles. These differences are primarily due to differing treatments of income and gains on various investment securities and foreign currency transactions held by the Fund, timing differences, and differing characterizations of distributions made by the Fund. Distributions from net investment income for federal income tax purposes include net realized gains on foreign currency transactions. These book/tax differences are either temporary or permanent in nature. To the extent these differences are permanent, adjustments are made to the appropriate capital accounts in the period when the differences arise. Permanent differences were primarily due to recharacterization of distributions and reclassifications of capital gains on passive foreign investment companies. These reclassifications have no impact on the NAV of the Fund. For the year ended December 31, 2009, reclassifications were made to decrease accumulated distributions in excess of net investment income by $30,482 and to increase accumulated net realized loss on investments and foreign currency transactions by $30,482.

The tax character of distributions paid during the years ended December 31, 2009 and December 31, 2008 was as follows:

	Year Ended		Year Ended
	December 31, 2009		December 31, 2008
Distributions paid from:
Ordinary income	$	135,478	$	653,920
Net long-term capital gains		—		659,849
Return of capital		14,430		19,686
Total distributions paid	$	149,908	$	1,333,455

Provision for Income Taxes. The Fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). It is the policy of the Fund to comply with the requirements of the Code applicable to regulated investment companies and to distribute substantially all of its net investment company taxable income and net capital gains. Therefore, no provision for federal income taxes is required.

At December 31, 2009, the components of accumulated earnings/losses on a tax basis were as follows:

Accumulated capital loss carryforwards	$	(40,219	)
Net unrealized appreciation on investments		4,781,182
Net unrealized appreciation on foreign currency translations		1,602
Total	$	4,742,565

At December 31, 2009, the Fund had net capital loss carryforwards for federal income tax purposes of $40,219, which are available to reduce future required distributions of net capital gains to shareholders through 2017.

At December 31, 2009, the difference between book basis and tax basis unrealized appreciation was primarily due to deferral of losses from wash sales for tax purposes and mark-to-market adjustments on passive foreign investment companies.

The following summarizes the tax cost of investments and the related unrealized appreciation/depreciation at December 31, 2009:

			Gross		Gross
			Unrealized		Unrealized			Net Unrealized
	Cost		Appreciation		Depreciation			Appreciation
Investments	$	24,281,383	$	6,854,614	$	(2,073,432	)	$	4,781,182

The Fund is required to evaluate tax positions taken or expected to be taken in the course of preparing the Fund’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Income tax and related interest and penalties would be recognized by the Fund as tax expense in the Statement of Operations if the tax positions were deemed to not meet the more-likely-than-not threshold. For the year ended December 31, 2009, the Fund did not incur any income tax, interest, or penalties. As of December 31, 2009, the Adviser has reviewed all open tax years and concluded that there was no impact to the Fund’s net assets or results of operations. Tax years ended December 31, 2007 through December 31, 2009, remain subject to examination by the Internal Revenue Service and state taxing authorities. On an ongoing basis, the Adviser will monitor its tax positions to determine if adjustments to this conclusion are necessary.

3. Investment Advisory Agreement and Other Transactions. The Fund has entered into an investment advisory agreement (the “Advisory Agreement”) with the Adviser which provides that the Fund will pay the Adviser a fee, computed daily and paid monthly, at the annual rate of 1.00% of the value of its average daily net assets. In accordance with the Advisory Agreement, the Adviser provides a continuous investment program for the Fund’s portfolio, oversees the administration of all aspects of the Fund’s business and affairs, and pays the compensation of all Officers and Directors of the Fund who are affiliated persons of the Adviser.

If total net assets of the Fund are below $100 million, the Fund pays each Director who is not considered to be an affiliated person an annual retainer of $1,000 plus $250 for each Board meeting attended and each Director is reimbursed by the Fund for any out of pocket expenses incurred in attending meetings. If total net assets of the Fund are in excess of $100 million, the Fund pays each Independent Director an annual retainer of $3,000 plus $500 for each Board meeting attended and each Director is reimbursed by the Fund for any out of pocket expenses incurred in attending meetings. All Board committee members receive $500 per meeting attended and the Chairman of the Audit Committee and the Lead Director each receive an annual fee of $1,000. A Director may receive a single meeting fee, allocated among the participating funds, for participation in certain meetings held on behalf of multiple funds. Directors who are directors or employees of the Adviser or an affiliated company receive no compensation or expense reimbursement from the Fund.

4. Distribution Plan. The Fund’s Board has adopted a distribution plan (the “Plan”) for each class of shares, except for Class I Shares, pursuant to Rule 12b-1 under the 1940 Act. Gabelli & Company, Inc. (“Gabelli & Company”), an affiliate of the Adviser, serves as distributor of the Fund. Under the Class AAA, Class A, Class B, and Class C Share Plans, payments are authorized to Gabelli & Company at annual rates of 0.25%, 0.25%, 1.00%, and 1.00%, respectively, of the average daily net assets of those classes, the annual limitations under each Plan. Such payments are accrued daily and paid monthly.

5. Portfolio Securities. Purchases and sales of securities for the year ended December 31, 2009, other than short-term securities and U.S. Government obligations, aggregated $3,317,661 and $8,091,089, respectively.

6. Transactions with Affiliates. During the year ended December 31, 2009, the Fund paid brokerage commissions on security trades of $240 to Gabelli & Company. Additionally, Gabelli & Company informed the Fund that it retained $110 from investors representing commissions (sales charges and underwriting fees) on sales and redemptions of Fund shares.

7. Line of Credit. The Fund participates in an unsecured line of credit of up to $75,000,000 under which it may borrow up to 10% of its net assets from the custodian for temporary borrowing purposes. Borrowings under this arrangement bear interest at the higher of the sum of the overnight LIBOR plus 100 basis points or the sum of the federal funds rate plus 100 basis points at the time of borrowing. This amount, if any, would be included in “interest expense” in the Statement of Operations. At December 31, 2009, there were no borrowings outstanding under the line of credit.

The average daily amount of borrowings outstanding under the line of credit during the year ended December 31, 2009 was $92,770 with a weighted average interest rate of 1.14%. The maximum amount borrowed at any time during the year ended December 31, 2009 was $1,447,000.

8. Capital Stock. The Fund offers five classes of shares — Class AAA Shares, Class A Shares, Class B Shares, Class C Shares, and Class I Shares. Class AAA Shares are offered without a sales charge only to investors who acquire them directly from Gabelli & Company, through selected broker/dealers, or the transfer agent. Class I Shares are offered to foundations, endowments, institutions, and employee benefit plans without a sales charge. Class A Shares are subject to a maximum front-end sales charge of 5.75%. Class B Shares are subject to a contingent deferred sales charge (“CDSC”) upon redemption within six years of purchase and automatically convert to Class A Shares approximately eight years after the original purchase. The applicable CDSC is equal to a declining percentage of the lesser of the NAV per share at the date of the original purchase or at the date of redemption, based on the length of time held. Class C Shares are subject to a 1.00% CDSC for one year after purchase. Class B Shares are available only through exchange of Class B Shares of other funds distributed by Gabelli & Company. Class I Shares were first issued on January 11, 2008.

The Fund imposes a redemption fee of 2.00% on all classes of shares that are redeemed or exchanged on or before the seventh day after the date of a purchase.The redemption fee is deducted from the proceeds otherwise payable to the redeeming shareholders and is retained by the Fund. The redemption fees retained by the Fund during the years ended December 31, 2009 and December 31, 2008 amounted to $321 and $1,770, respectively.

The redemption fee does not apply to redemptions of shares where (i) the shares were purchased through automatic reinvestment of distributions, (ii) the redemption was initiated by the Fund, (iii) the shares were purchased through programs that collect the redemption fee at the program level and remit them to the Fund, or (iv) the shares were purchased through programs that the Adviser determines to have appropriate anti-short-term trading policies in place or as to which the Adviser has received assurances that look-through redemption fee procedures or effective anti-short-term trading policies and procedures are in place.

9. Indemnifications. The Fund enters into contracts that contain a variety of indemnifications. The Fund’s maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

GAMCO International Growth Fund, Inc.

10. Other Matters. On April 24, 2008, the Adviser entered into an administrative settlement with the SEC to resolve the SEC’s inquiry regarding prior frequent trading activity in shares of the GAMCO Global Growth Fund (the “Global Growth Fund”) by one investor who was banned from the Global Growth Fund in August 2002. In the settlement, the SEC found that the Adviser had violated Section 206(2) of the Investment Advisers Act, Section 17(d) of the 1940 Act, and Rule 17d-1 thereunder, and had aided and abetted and caused violations of Section 12(d)(1)(B)(i) of the 1940 Act. Under the terms of the settlement, the Adviser, while neither admitting nor denying the SEC’s findings and allegations, agreed, among other things, to pay the previously reserved total of $16 million (including a $5 million penalty), of which at least $11 million will be distributed to shareholders of the Global Growth Fund in accordance with a plan being developed by an independent distribution consultant and approved by the independent directors of the Global Growth Fund and the staff of the SEC, and to cease and desist from future violations of the above referenced federal securities laws. The settlement will not have a material adverse impact on the Adviser or its ability to fulfill its obligations under the Advisory Agreement. On the same day, the SEC filed a civil action against the Executive Vice President and Chief Operating Officer of the Adviser, alleging violations of certain federal securities laws arising from the same matter. The officer is also an officer of the Global Growth Fund and other funds in the Gabelli/GAMCO fund complex including the Fund. The officer denies the allegations and is continuing in his positions with the Adviser and the funds. The Adviser currently expects that any resolution of the action against the officer will not have a material adverse impact on the Fund or the Adviser or its ability to fulfill its obligations under the Advisory Agreement.

11. Subsequent Events. Management has evaluated the impact on the Fund of events occurring subsequent to December 31, 2009 through February 25, 2010, the date the financial statements were issued, and has determined that there were no subsequent events requiring recognition or disclosure in the financial statements.

GAMCO International Growth Fund, Inc.
Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of
GAMCO International Growth Fund, Inc.

We have audited the accompanying statement of assets and liabilities of GAMCO International Growth Fund, Inc. (the “Fund”), including the schedule of investments, as of December 31, 2009, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2009, by correspondence with the Fund’s custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. 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 GAMCO International Growth Fund, Inc. at December 31, 2009, 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 the financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

(a)	The registrant, as of the end of the period covered by this report, has adopted a code of ethics that applies to the registrant’s principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, regardless of whether these individuals are employed by the registrant or a third party.

Item 4. Principal Accountant Fees and Services.

Audit Fees

(a) The aggregate fees billed for each of the last two fiscal years for professional services rendered by the principal accountant for the audit of the registrant’s annual financial statements or services that are normally provided by the accountant in connection with statutory and regulatory filings or engagements for those fiscal years are $39,200 for 2008 and $37,200 for 2009.

Audit-Related Fees

(b) The aggregate fees billed in each of the last two fiscal years for assurance and related services by the principal accountant that are reasonably related to the performance of the audit of the registrant’s financial statements and are not reported under paragraph (a) of this Item are $0 for 2008 and $0 for 2009.

Tax Fees

(c) The aggregate fees billed in each of the last two fiscal years for professional services rendered by the principal accountant for tax compliance, tax advice, and tax planning are $4,300 for 2008 and $4,300 for 2009. Tax fees represent tax compliance services provided in connection with the review of the Registrant’s tax returns.

All Other Fees

(d) The aggregate fees billed in each of the last two fiscal years for products and services provided by the principal accountant, other than the services reported in paragraphs (a) through (c) of this Item are $0 for 2008 and $0 for 2009.

(e)(1)	Disclose the audit committee’s pre-approval policies and procedures described in paragraph (c)(7) of Rule 2-01 of Regulation S-X.
	Pre-Approval Policies and Procedures. The Audit Committee (“Committee”) of the registrant is responsible for pre-approving (i) all audit and permissible non-audit services to be provided by the independent registered public accounting firm to the registrant and (ii) all permissible non-audit services to be provided by the independent registered public accounting firm to the Adviser, Gabelli Funds, LLC, and any affiliate of Gabelli Funds, LLC (“Gabelli”) that provides services to the registrant (a “Covered Services Provider”) if the independent registered public accounting firm’s engagement related directly to the operations and financial reporting of the registrant. The Committee may delegate its responsibility to pre-approve any such audit and permissible non-audit services to the Chairperson of the Committee, and the Chairperson must report to the Committee, at its next regularly scheduled meeting after the Chairperson’s pre-approval of such services, his or her decision(s). The Committee may also establish detailed pre-approval policies and procedures for pre-approval of such services in accordance with applicable laws, including the delegation of some or all of the Committee’s pre-approval responsibilities to the other persons (other than Gabelli or the registrant’s officers). Pre-approval by the Committee of any permissible non-audit services is not required so long as: (i) the permissible non-audit services were not recognized by the registrant at the time of the engagement to be non-audit services; and (ii) such services are promptly brought to the attention of the Committee and approved by the Committee or Chairperson prior to the completion of the audit.
(e)(2)	The percentage of services described in each of paragraphs (b) through (d) of this Item that were approved by the audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X are as follows:

(b)	N/A
(c)	100%
(d)	N/A

(f) The percentage of hours expended on the principal accountant’s engagement to audit the registrant’s financial statements for the most recent fiscal year that were attributed to work performed by persons other than the principal accountant’s full-time, permanent employees was zero percent (0%).

(g)

The aggregate non-audit fees billed by the registrant’s accountant for services rendered to the registrant, and rendered to the registrant’s investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant for each of the last two fiscal years of the registrant was $4,300 for 2008 and $4,300 for 2009.

(h)

The registrant’s audit committee of the board of directors has considered whether the provision of non-audit services that were rendered to the registrant’s investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant’s independence.

Exhibit 99.CODE ETH

GAMCO INVESTORS, INC. and AFFILIATES

Joint Code of Ethics for Chief Executive
And Senior Financial Officers of the Gabelli Funds

          Each affiliated registered investment company (each a “Company”) is committed to conducting business in accordance with applicable laws, rules and regulations and the highest standards of business ethics, and to full and accurate disclosure — financial and otherwise — in compliance with applicable law. This Code of Ethics, applicable to each Company’s Chief Executive Officer, President, Chief Financial Officer and Treasurer (or persons performing similar functions) (together, “Senior Officers”), sets forth policies to guide you in the performance of your duties.

          As a Senior Officer, you must comply with applicable law. You also have a responsibility to conduct yourself in an honest and ethical manner. You have leadership responsibilities that include creating a culture of high ethical standards and a commitment to compliance, maintaining a work environment that encourages the internal reporting of compliance concerns and promptly addressing compliance concerns.

          This Code of Ethics recognizes that the Senior Officers are subject to certain conflicts of interest inherent in the operation of investment companies, because the Senior Officers currently or may in the future serve as Senior Officers of each of the Companies, as officers or employees of the investment advisor to the Companies or service providers thereof (the “Advisor”) and/or affiliates of the Advisor (the “Advisory Group”) and as officers or trustees/directors of other registered investment companies and unregistered investment funds advised by the Advisory Group. This Code of Ethics also recognizes that certain laws and regulations applicable to, and certain policies and procedures adopted by, the Companies or the Advisory Group govern your conduct in connection with many of the conflict of interest situations that arise in connection with the operations of the Companies, including:

• the Investment Company Act of 1940, and the rules and regulation promulgated thereunder by the Securities and Exchange Commission (the “1940 Act”);

• the Investment Advisers Act of 1940, and the rules and regulations promulgated thereunder by the Securities and Exchange Commission (the “Advisers Act”);

• the Code of Ethics adopted by each Company pursuant to Rule 17j-1(c) under the 1940 Act (collectively, the “Trust’s 1940 Act Code of Ethics”);

Revised: June 1, 2006

• one or more codes of ethics adopted by the Advisory Group that have been reviewed and approved by those trustees/directors (the “Directors”) of each Company that are not “interested persons” of such Company (the “Independent Directors”) within the meaning of the 1940 Act (the “Advisory Group’s 1940 Act Code of Ethics” and, together with such Company’s 1940 Act Code of Ethics, the “1940 Act Codes of Ethics”);

• the policies and procedures adopted by each Company to address conflict of interest situations, such as procedures under Rule 10f-3, Rule 17a-7 and Rule 17e-1 under the 1940 Act (collectively, the “Conflict Policies”); and

• the Advisory Group’s policies and procedures to address, among other things, conflict of interest situations and related matters (collectively, the “Advisory Policies”).

The provisions of the 1940 Act, the Advisers Act, the 1940 Act Codes of Ethics, the Conflict Policies and the Advisory Policies are referred to herein collectively as the “Additional Conflict Rules”.

          This Code of Ethics is different from, and is intended to supplement, the Additional Conflict Rules. Accordingly, a violation of the Additional Conflict Rules by a Senior Officer is hereby deemed not to be a violation of this Code of Ethics, unless and until the Directors shall determine that any such violation of the Additional Conflict Rules is also a violation of this Code of Ethics.

Senior Officers Should Act Honestly and Candidly

          Each Senior Officer has a responsibility to each Company to act with integrity. Integrity requires, among other things, being honest and candid. Deceit and subordination of principle are inconsistent with integrity.

          Each Senior Officer must:

• act with integrity, including being honest and candid while still maintaining the confidentiality of information where required by law or the Additional Conflict Rules;

• comply with the laws, rules and regulations that govern the conduct of each Company’s operations and report any suspected violations thereof in accordance with the section below entitled “Compliance With Code Of Ethics”; and

• adhere to a high standard of business ethics.

Revised: June 1, 2006

Conflicts Of Interest

          A conflict of interest for the purpose of this Code of Ethics occurs when your private interests interfere in any way, or even appear to interfere, with the interests of a Company.

          Senior Officers are expected to use objective and unbiased standards when making decisions that affect each Company, keeping in mind that Senior Officers are subject to certain inherent conflicts of interest because Senior Officers of a Company also are or may be officers of other Companies and/or the Advisory Group (as a result of which it is incumbent upon you to be familiar with and to seek to comply with the Additional Conflict Rules).

          You are required to conduct the business of each Company in an honest and ethical manner, including the ethical handling of actual or apparent conflicts of interest between personal and business relationships. When making any investment, accepting any position or benefits, participating in any transaction or business arrangement or otherwise acting in a manner that creates or appears to create a conflict of interest with respect to each Company where you are receiving a personal benefit, you should act in accordance with the letter and spirit of this Code of Ethics.

          If you are in doubt as to the application or interpretation of this Code of Ethics to you as a Senior Officer of a Company, you should make full disclosure of all relevant facts and circumstances to the Chief Compliance Officer of the Advisory Group (the “CCO”) and obtain the approval of the CCO prior to taking action.

          Some conflict of interest situations that should always be approved by the CCO, if material, include the following:

• the receipt of any entertainment or non-nominal gift by the Senior Officer, or a member of his or her family, from any company with which a Company has current or prospective business dealings (other than the Advisory Group), unless such entertainment or gift is business related, reasonable in cost, appropriate as to time and place, and not so frequent as to raise any question of impropriety;

• any ownership interest in, or any consulting or employment relationship with, of any of the Companies’ service providers, other than the Advisory Group; or

• a direct or indirect financial interest in commissions, transaction charges or spreads paid by a Company for effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Senior Officer’s employment by the Advisory Group, such as compensation or equity ownership.

Revised: June 1, 2006

Disclosures

          It is the policy of each Company to make full, fair, accurate, timely and understandable disclosure in compliance with all applicable laws and regulations in all reports and documents that such Company files with, or submits to, the Securities and Exchange Commission or a national securities exchange and in all other public communications made by such Company. As a Senior Officer, you are required to promote compliance with this policy and to abide by such Company ’s standards, policies and procedures designed to promote compliance with this policy.

Each Senior Officer must:
•	familiarize himself or herself with the disclosure requirements applicable to each Company as well as the business and financial operations of each Company; and
•	not knowingly misrepresent, or cause others to misrepresent, facts about any Company to others, including to the Directors, such Company’s independent auditors, such Company’s counsel, any counsel to the Independent Directors, governmental regulators or self-regulatory organizations.

Compliance With Code Of Ethics

          If you know of or suspect a violation of this Code of Ethics or other laws, regulations, policies or procedures applicable to the Trust, you must report that information on a timely basis to the CCO or report it anonymously by following the “whistle blower” policies adopted by the Advisory Group from time to time. No one will be subject to retaliation because of a good faith report of a suspected violation.

          Each Company will follow these procedures in investigating and enforcing this Code of Ethics, and in reporting on this Code of Ethics:

• the CCO will take all appropriate action to investigate any actual or potential violations reported to him or her;

• violations and potential violations will be reported to the Board of Directors of each affected Company after such investigation;

• if the Board of Directors determines that a violation has occurred, it will take all appropriate disciplinary or preventive action; and

• appropriate disciplinary or preventive action may include a letter of censure, suspension, dismissal or, in the event of criminal or other serious violations of law, notification of the Securities and Exchange Commission or other appropriate law enforcement authorities.

Waivers Of Code Of Ethics

          Except as otherwise provided in this Code of Ethics, the CCO is responsible for applying this Code of Ethics to specific situations in which questions are presented to the CCO and has the authority to interpret this Code of Ethics in any particular situation. The CCO shall take all action he or she considers appropriate to investigate any actual or potential violations reported under this Code of Ethics.

          The CCO is authorized to consult, as appropriate, with the chair of the Governance Committee and with counsel to the affected Company, the Advisory Group or the Independent Directors, and is encouraged to do so.

          The Board of Directors, the affected Company is responsible for granting waivers of this Code of Ethics, as appropriate. Any changes to or waivers of this Code of Ethics will, to the extent required, be disclosed on Form N-CSR, or otherwise, as provided by Securities and Exchange Commission rules.

Recordkeeping

          Each Company will maintain and preserve for a period of not less than six (6) years from the date an action is taken, the first two (2) years in an easily accessible place, a copy of the information or materials supplied to the Boards of Directors pursuant to this Code of Ethics:

• that provided the basis for any amendment or waiver to this Code of Ethics; and

• relating to any violation of this Code of Ethics and sanctions imposed for such violation, together with a written record of the approval or action taken by the relevant Board of Directors.

Confidentiality

          All reports and records prepared or maintained pursuant to this Code of Ethics shall be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code of Ethics, such matters shall not be disclosed to anyone other than the Independent Trustees and their counsel, the Companies and their counsel, the Advisory Group and its counsel and any other advisors, consultants or counsel retained by the Directors, the Independent Directors or any committee of Directors.

Amendments

          This Code of Ethics may not be amended as to any Company except in written form, which is specifically approved by a majority vote of the affected Company’s Directors, including a majority of its Independent Directors.
