A corporation may, in advance of the final disposition of any civil, criminal, administrative or investigative action, suit or proceeding, pay the expenses (including attorneys' fees) incurred by any officer, director, employee or agent in defending such action, provided that the director or officer undertakes to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the corporation. A corporation may indemnify such person against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful.</div>

EXPLANATORY NOTE
Houston American Energy Corp. ("HUSA" "we" or "us") previously filed a Form S-8 (Registration No. 333-151824) registering 2,200,000 shares of common stock, $0.001 par value per share, under the Houston American Energy Corp. 2008 Equity Incentive Plan (the "2008 Plan").  Our board of directors unanimously adopted, and during 2013 our shareholders approved, an amendment to the 2008 Plan (the "2008 Plan Amendment") to increase the number of shares covered by, and reserved for issuance under, the 2008 Plan from 2,200,000 shares to 6,000,000 shares.  This registration statement registers the offer and sale of the additional 3,800,000 shares of common stock available for grants under the 2008 Plan pursuant to the 2008 Plan Amendment.
We previously filed a Form S-8 (SEC file no. 333-127656) registering 500,000 shares of common stock under the Houston American Energy Corp. 2005 Stock Option Plan (the "2005 Plan").
This Form S-8 includes a reoffer prospectus prepared in accordance with Part I of Form S-3 under the Securities Act of 1933, as amended. The reoffer prospectus may be used for reoffers and resales of control securities (as such term is defined in General Instruction C to Form S-8) acquired pursuant to the 2008 Plan and the 2005 Plan by selling stockholders who may be deemed "affiliates" (as such term is defined in Rule 405 of the Securities Act of 1933, as amended) of HUSA and for reoffers and resales of restricted securities (as such term is defined in General Instruction C to Form S-8) acquired pursuant to awards of restricted stock issued pursuant to the 2008 Plan.
As permitted by Rule 429 under the Securities Act of 1933, the prospectus filed together with this registration statement is a combined resale prospectus that shall be deemed a post-effective amendment to the registrant's registration statements numbered 333-151824 and 333-127656 on Form S-8.

Item 6.
Indemnification of Directors and Officers.
Section 145 of the Delaware General Corporation Law (the "DGCL") empowers a Delaware corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation) by reason of the fact that such person is or was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. A corporation may, in advance of the final disposition of any civil, criminal, administrative or investigative action, suit or proceeding, pay the expenses (including attorneys' fees) incurred by any officer, director, employee or agent in defending such action, provided that the director or officer undertakes to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the corporation. A corporation may indemnify such person against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful.
II-1
A Delaware corporation may indemnify officers and directors in an action by or in the right of the corporation to procure a judgment in its favor under the same conditions, except that no indemnification is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses (including attorneys fees) that he actually and reasonably incurred in connection therewith. The indemnification provided is not deemed to be exclusive of any other rights to which an officer or director may be entitled under any corporation's by-law, agreement, vote or otherwise.
In accordance with Section 145 of the DGCL, our Certificate of Incorporation (the "Certificate") provides that we shall indemnify each person who is or was a director, officer, employee or agent of the company (including the heirs, executors, administrators or estate of such person) or is or was serving at the request of the company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, to the fullest extent permitted. The indemnification provided by the Certificate shall not be deemed exclusive of any other rights to which any of those seeking indemnification or advancement of expenses may be entitled under any by-law, agreement, vote of stockholder or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person. Expenses (including attorneys' fees) incurred in defending a civil, criminal, administrative or investigative action, suit or proceeding shall be paid by the company in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of the indemnified person to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the company. The Certificate provides that a director of the company shall not be personally liable to the company or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the company or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit.

Item 9.
Undertakings.
The undersigned registrant hereby undertakes:
(1)
To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i)
To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;
(ii)
To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information in the registration statement;
(iii)
To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
Provided, however, that the undertakings set forth in paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act that are incorporated by reference in the registration statement.
(2)
That, for the purpose of determining liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial
bona fide
offering thereof.
(3)
To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial
bona fide
offering thereof.
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
II-3
SIGNATURES
Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Houston, State of Texas on this 9th day of September 2015.

RISK FACTORS
Investing in our securities involves risks. Before making an investment decision, you should carefully consider the risk factors discussed in "Item 1A. Risk Factors" and elsewhere in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014 and in our more recent filings with the SEC which are incorporated by reference herein, as well as other information we include in this prospectus. See "Incorporation by Reference" above.  Additional risks and uncertainties not presently known to us or that we deem currently immaterial may also impair our business operations. The risks and uncertainties described in our filings with the SEC are not the only ones facing us. Additional risks and uncertainties that we are unaware of, or that we currently deem immaterial, also may become important factors that affect us. If any of the following risks occur, our business, financial condition or results of operations could be materially and adversely affected.
FORWARD-LOOKING STATEMENTS
This prospectus contains "forward-looking statements," which include information relating to future events, future financial performance, strategies, expectations, competitive environment and regulations. Words such as "may," "should," "could," "would," "predicts," "potential," "continue," "expects," "anticipates," "future," "intends," "plans," "believes," "estimates," and similar expressions, as well as statements in future tense, identify forward-looking statements. Forward-looking statements should not be read as a guarantee of future performance or results and will probably not be accurate indications of when such performance or results will be achieved. Forward-looking statements are based on information we have when those statements are made or our management's good faith belief as of that time with respect to future events, and are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements.
You should review carefully the section entitled "Risk Factors" above for a discussion of these and other risks that relate to our business and investing in shares of our common stock.
USE OF PROCEEDS
We will not receive any of the proceeds from the sale of the common stock offered by this prospectus, but we will receive the exercise price upon the exercise of any options by the selling stockholders. We plan to use any such proceeds for working capital purposes.
SELLING STOCKHOLDERS
This prospectus relates to shares of our common stock that are being registered for reoffers and resales by selling stockholders who are current or former directors, officers, employees and consultants and have acquired or may acquire shares under our employee benefit plans (including adjustment shares). The selling stockholders may resell any or all of the shares, when issued, subject to vesting conditions in some cases, while this prospectus is effective.
Executive officers and directors, their family members, trusts for their benefit, or entities that they control, that acquire common stock under our benefit plans may be added to the selling stockholder list below by a prospectus supplement filed with the SEC. The number of shares available to be sold by any selling stockholder under this prospectus also may be increased or decreased by a prospectus supplement, subject to the aggregate number of shares included within this Prospectus. Non-affiliates who acquired restricted securities, as these terms are defined in Rule 144(a) under the Securities Act of 1933, under any of our employee benefit plans and who are not named below may use this prospectus for the offer or sale of their common stock if they hold 1,000 shares or less. Although a person's name is included in the table below, neither that person nor we are making an admission that the named person is our "affiliate."
The information in the table below sets forth, for each selling stockholder, based upon information available to us as of August 13, 2015, the number of shares of our common stock beneficially owned before and after the sale of the shares (assuming the sales of all shares) and the percentage of the outstanding shares of our common stock beneficially owned after the sale of the shares.

Table of Contents
The table below also sets forth "Shares Available to be Sold", which represents the maximum number of shares that could be sold under this prospectus by the holder assuming the vesting of all awards, achievement of all performance criteria and exercise of all options. The amounts listed under "Shares Available to be Sold" do not constitute commitments to sell any or all of the stated number of shares.
The actual number of shares to be sold, if any, shall be determined from time to time by each Selling Stockholder in his or her discretion. We have not been informed whether any selling stockholders intend to sell any shares.

PLAN OF DISTRIBUTION
We are registering shares of common stock underlying options granted, and shares of restricted stock issued, under our 2005 Stock Option Plan and 2008 Equity Incentive Plan for resale by the selling stockholders from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale by the selling stockholders of such shares of common stock. We will bear all fees and expenses incident to our obligation to register the shares of common stock.
The selling stockholders may sell all or a portion of the shares of common stock beneficially owned by them and offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If the shares of common stock are sold through underwriters or broker-dealers, the selling stockholders will be responsible for underwriting discounts or commissions or agent's commissions. The shares of common stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale or at negotiated prices. Sales may be effected in transactions, which may involve crosses or block transactions:
·
on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale;
·
in the over-the-counter market;
·
in transactions otherwise than on such exchanges or systems or in the over-the-counter market;
·
through the writing and exercise of options, whether such options are listed on an options exchange or otherwise;
·
ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
·
block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;
·
purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
·
an exchange distribution in accordance with the rules of the applicable exchange;
·
privately negotiated transactions;
·
short sales;
·
broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;
·
any combination of any such methods of sale; and
·
any other method permitted by applicable law.
If the selling stockholders effect such transactions by selling shares of common stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the shares of common stock for whom they may act as agent or to whom they may sell as principal. These discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved. In connection with sales of the shares of common stock or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of common stock in the course of hedging in positions they assume. The selling stockholders may also sell shares of common stock short and deliver shares of common stock covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling stockholders may also loan or pledge shares of common stock to broker-dealers that in turn may sell such shares.

The selling stockholders may pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933, as amended, amending, if necessary, the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer and donate the shares of common stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.
The selling stockholders and any broker-dealer participating in the distribution of the shares of common stock may be deemed to be "underwriters" within the meaning of the Securities Act of 1933, as amended, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act of 1933, as amended. At the time a particular offering of the shares of common stock is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of shares of common stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling stockholders and any discounts, commissions or concessions allowed or reallowed or paid to broker-dealers.
Under the securities laws of some states, the shares of common stock may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares of common stock may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.
There can be no assurance that any selling stockholder will sell any or all of the shares of common stock registered by the registration statement of which this prospectus forms a part.
The selling stockholders and any other person participating in such distribution will be subject to applicable provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder, including, without limitation, Regulation M of the Securities Exchange Act of 1934, as amended, which may limit the timing of purchases and sales of any of the shares of common stock by the selling stockholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares of common stock to engage in market-making activities with respect to the shares of common stock. All of the foregoing may affect the marketability of the shares of common stock and the ability of any person or entity to engage in market-making activities with respect to the shares of common stock.
We will pay all expenses of the registration of the shares of common stock pursuant to the registration rights agreement that we entered into with the selling stockholders. However, the selling stockholders will pay all underwriting discounts and selling commissions, if any.
We do not know whether any of the selling stockholders will sell any or all of their shares under this prospectus. We may terminate this offering without notice at any time.

INDEMNIFICATION FOR SECURITIES ACT LIABILITIES
Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to our directors, officers or persons controlling us, we have been advised that it is the Securities and Exchange Commission's opinion that such indemnification is against public policy as expressed in the Securities Act of 1933, as amended, and is, therefore, unenforceable.
