INTRODUCTION
The Annual Meeting of Stockholders of Adams Natural Resources Fund, Inc., a Maryland corporation (the “Fund”), will be held on Thursday, April 21, 2022, at 10:00 a.m., local time, at the Fund’s offices at 500 E. Pratt Street, Suite 1300, Baltimore, MD 21202, for the purposes set forth in the accompanying Notice of Annual Meeting and also set forth below. This proxy statement is furnished in connection with the solicitation by the Board of Directors of proxies to be used at the meeting and at any and all adjournments or postponements thereof and is first being provided to stockholders on or about February 16, 2022.
At the Annual Meeting, action is to be taken on (1) the election of a Board of Directors; (2) the ratification of the selection of an independent registered public accounting firm; and (3) the transaction of such other business as may properly come before the meeting or any adjournment or postponement thereof.
Important Notice Regarding the Availability of Proxy Materials for the
Stockholder Meeting to Be Held On April 21, 2022:
This Proxy Statement, the Notice of Annual Meeting, a form of the proxy, and the 2021 Annual Report to stockholders are all available on the internet at the following website:
http://www.astproxyportal.com/ast/13580/
How You May Vote and Voting By Proxy
You can provide voting instructions by using telephone or internet options as instructed in the enclosed proxy card, or by dating, executing and mailing the proxy card. You may also vote in person at the Annual Meeting, however, even if you intend to do so, please provide voting instructions by one of the methods described above. Except for Proposals (1) and (2), referred to above, the proxies confer discretionary authority on the persons named therein or their substitutes with respect to any business that may properly come before the meeting. Stockholders retain the right to revoke executed proxies at any time before they are voted by written notice to the Fund, by executing a later dated proxy, or by appearing and voting at the meeting. All shares represented at the meeting by proxies in the accompanying form will be voted, provided that such proxies are properly executed. In cases where a choice is indicated, the shares represented will be voted in accordance with the specifications so made. In cases where no specifications are made, the shares represented will be voted FOR Proposal (1) and FOR Proposal (2).
If your shares are held in the name of a bank, broker, or other holder of record, you will receive instructions from the holder of record that you must follow in order to vote your shares. If your shares are not registered in your own name and you plan to vote your shares in person at the Annual Meeting, you should contact your broker or agent to obtain a broker’s proxy card and bring it with you to the Annual Meeting in order to vote.

TABLE OF CONTENTS​​​​​​
If you have questions regarding how to attend the meeting and vote in person, please contact the Secretary of the Fund by telephone at (800) 638-2479 or by email at investorrelations@adamsfunds.com.
Who May Vote
Only stockholders of record at the close of business on January 28, 2022, may vote at the Annual Meeting. The total number of shares of common stock of the Fund (“Common Stock”) outstanding and entitled to be voted on the record date was 24,466,617. Each share is entitled to one vote. The Fund has no other class of security outstanding.
Vote Requirement
For Proposal (1), referred to above, directors shall be elected by a plurality of the votes cast at the meeting. Proposal (2), referred to above, requires the affirmative vote of a majority of the votes cast at the meeting.
Quorum Requirement
A quorum is necessary to hold a valid meeting. If stockholders entitled to cast a majority of all the votes entitled to be cast at the Annual Meeting are present in person or by proxy, a quorum will exist. Proxies received by the Fund that are marked “withhold authority” or abstain, or that constitute a broker non-vote, are counted as present for purposes of establishing a quorum. A broker non-vote occurs when a broker returns a valid proxy but does not vote on a particular matter because the broker does not have the discretionary voting power for that matter and has not received instructions from the beneficial owner. Proxies marked “withhold authority,” abstentions, and broker non-votes do not count as votes cast with respect to any proposal, and therefore, such proxies would have no effect on the outcome of Proposals (1) and (2) above.
Appraisal Rights
Under Maryland law, there are no appraisal or other dissenter rights with respect to any matter to be voted on at the Annual Meeting that is described herein.
Other Matters
The Fund will pay all costs of soliciting proxies for the Annual Meeting. Solicitation will be made by mail, and officers, employees, and agents of the Fund may also solicit proxies by telephone or personal interview. The Fund has retained AST Fund Solutions, LLC to assist in the solicitation of proxies. The Fund will pay AST Fund Solutions, LLC a fee for its services, not to exceed $2,500, and will reimburse AST Fund Solutions, LLC for its expenses, which the Fund estimates should be approximately $1,500. The Fund expects to request brokers and nominees who hold stock in their names to furnish this proxy material to their customers and to solicit proxies from them, and will reimburse such brokers and nominees for their out-of-pocket and reasonable clerical expenses in connection therewith.
Fund Complex
The Fund is part of Adams Funds (the “Fund Complex”), which is composed of the Fund and Adams Diversified Equity Fund, Inc. ("ADX"), a closed-end investment company that is also traded on the New York Stock Exchange.

As of December 31, 2021.
​
The Board has adopted equity ownership requirements for the directors and senior staff. Under these equity ownership requirements, the Chief Executive Officer, portfolio managers, research analysts, and other executive officers must own a certain value of equity in the Fund Complex with a cost basis equal to a multiple of salary. Non-employee directors must own at least $100,000 by cost basis of the Fund’s Common Stock within 5 years of joining the Board.
The nominees for election as directors of the Fund identified above are also the nominees for election to the Board of Directors of ADX, part of the Fund Complex.
Board Leadership Structure
Six of the Fund’s seven directors are not “interested persons,” as defined by the Investment Company Act of 1940, as amended (the “Act”), and are independent directors. Mr. Stoeckle is the only member of the Board who is an “interested person” under the Act and thus is not an independent director. The Board has elected Dr. Kathleen T. McGahran, an Independent Director, to serve as the Chair of the Board.
Board’s Oversight of Risk Management for the Fund
The Board’s role in risk management of the Fund is that of oversight. The internal staff of portfolio managers, research analysts, and administrative personnel is responsible for the day-to-day management of the Fund, including risk management in such aspects as investment performance and investment risk, valuation risk, issuer and counterparty credit risk, compliance risk, and operational risk. As part of its oversight, the Board has delegated to the Audit Committee the primary role of overseeing the assessment and management of risks, including major financial risks, by the Fund’s management and the steps that management has taken to monitor and control such risks. The Audit Committee reports to the Board at least quarterly on its discussions of these items with management. In addition, the Board, acting at its regularly scheduled meetings, receives reports from senior management, including the Fund’s portfolio management team, the Chief Compliance Officer, and the Chief Financial Officer. Between Board meetings, the Executive Committee, and/or the Chair of the Board, and/or the Chairman of the Audit Committee, as appropriate, interact with the CEO and other senior executives on any matter requiring action by or notice to the Board. The Board also receives periodic presentations from senior management regarding specific operational, compliance, or investment areas, such as business continuity, personal trading, valuation, investment research, and securities lending, and receives reports from the Fund’s General Counsel regarding regulatory, compliance, and governance matters. The Fund believes that its leadership structure enhances risk oversight. It should be noted that, in its oversight role, the Board is not a guarantor of the Fund’s investments or activities.
Process for Stockholders to Communicate with Board
The Board of Directors has implemented a process for stockholders of the Fund to send communications to the Board. Any stockholder desiring to communicate with the Board, or with specific individual directors, may do so by writing to the Secretary of the Fund at Adams Natural Resources Fund, Inc., 500 E. Pratt Street, Suite 1300, Baltimore, MD 21202, or by sending an email message to the Secretary at investorrelations@adamsfunds.com.The Secretary has been instructed by the Board to promptly forward all such communications to the addressees indicated thereon.

Each director and officer of the Fund who is subject to Section 16 of the Securities Exchange Act of 1934, as amended, and persons who own more than ten percent of a registered class of the Fund’s securities are required to report to the Securities and Exchange Commission (the “Commission”) by a specified date his or her beneficial ownership of or transactions in the Fund’s securities. Based upon a review of filings with the Commission, such forms received by the Fund, and written representations that no other reports are required, the Fund believes that each director and officer, with one exception, filed all requisite reports with the Commission on a timely basis during 2021. The Fund had no greater-than-ten-percent beneficial owners in 2021.

Audit Committee
Mr. Dale (Chair), Dr. Arzac, Dr. Gale, Ms. Jammet, and Ms. Musser Nelson, each of whom is an independent director as such is defined by the rules of the New York Stock Exchange, and none of whom is an “interested person” as such is defined by the Act, constitute the membership of the Board’s Audit Committee, which met four times in 2021. Ms. Musser Nelson joined the Board and was appointed to the Audit Committee on December 9, 2021. The Board has determined each of Mr. Dale, Dr. Arzac, Ms. Jammet, and Ms. Musser Nelson to be an audit committee financial expert, as that term is defined in federal securities regulations. The Board has adopted a written charter under which the Committee operates. A copy of the Audit Committee Charter (“Charter”) is available on the Fund’s website: adamsfunds.com. Set forth below is the report of the Committee:
Audit Committee Report
The purposes of the Audit Committee are set forth in the Committee’s written Charter. As provided in the Charter, the role of the Committee is to assist the Board of Directors in its oversight on matters relating to accounting, financial reporting, internal control, auditing, risk assessment and risk management, regulatory compliance activities, and other matters the Board deems appropriate. The Committee also selects the Fund’s independent registered public accounting firm in accordance with the provisions set out in the Charter. Management, however, is responsible for the preparation, presentation, and integrity of the Fund’s financial statements, and for the procedures designed to
11

TABLE OF CONTENTS
assure compliance with accounting standards and applicable laws and regulations. The independent registered public accounting firm is responsible for planning and carrying out proper audits.
In fulfilling its responsibilities, the Committee has reviewed and discussed the audited financial statements contained in the 2021 Annual Report of the Fund with the Fund’s management and with PricewaterhouseCoopers LLP (“PwC”), the Fund’s independent registered public accounting firm. In addition, the Committee has discussed with PwC the matters required to be discussed pursuant to Statement of Auditing Standards No. 61, as modified or supplemented. The Committee has also received from PwC the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding PwC’s communications with the Committee concerning independence, considered whether the provision of nonaudit services by PwC is compatible with maintaining PwC’s independence, and discussed with PwC its independence.
In reliance on the reviews and discussions with management and PwC referred to above, and subject to the limitations on the responsibilities and role of the Committee set forth in the Charter and discussed above, the Committee recommended to the Board of Directors, and the Board has approved, that the audited financial statements be included in the Fund’s 2021 Annual Report for filing with the Securities and Exchange Commission.
Respectfully submitted on February 10, 2022, by the members of the Audit Committee of the Board of Directors:

​ | ​ | ​ | ​ | Kenneth J. Dale, Chair Enrique R. Arzac Roger W. Gale Mary Chris Jammet Jane Musser Nelson | ​

Compensation Committee
Ms. Kloppenburg (Chair), Mr. Dale, Mr. Escherich, and Dr. Gale constituted the membership of the Board’s Compensation Committee, which met two times in 2021. The Committee reviews and recommends changes in the compensation of the directors, officers, and employees, including salaries and the cash incentive compensation plans in which the executive officers, officers and employees of the Fund are eligible to participate. The Board has adopted a written charter under which the Compensation Committee operates, a copy of which is available on the Fund’s website: adamsfunds.com.
Executive Committee
Dr. McGahran (Chair), Mr. Dale, Mr. Escherich, Ms. Kloppenberg, and Mr. Stoeckle constitute the membership of the Board’s Executive Committee, which met two times in 2021.

12

TABLE OF CONTENTS​​
Each of the members of the Committee is an independent director as such is defined by the rules of the New York Stock Exchange and none is an “interested person” as such term is defined by the Act.
Among other responsibilities, the Committee supervises and reviews Board composition, director nominations, and corporate governance matters. For director nominations, the Committee leads the search for qualified director candidates, including canvassing, recruiting, evaluating and recommending nominees to the full Board. The Committee has used a third-party search firm to help identify candidates who may meet the needs of the Board.
Stockholders may recommend candidates for consideration by the Committee by writing to the Secretary of the Fund at the office of the Fund, 500 E. Pratt Street, Suite 1300, Baltimore, MD 21202, giving the candidate’s name, biographical data, and qualifications, and stating whether the candidate would be an “interested person” of the Fund. A written statement from the candidate, consenting to be named as a candidate, and if nominated and elected, to serve as a director, should accompany any such recommendation.
The Board appreciates the value of diversity in its membership. In practice, when evaluating director candidates, the Committee and the full Board considers the diversity of skills, experience and/or perspective a prospective nominee would bring to the Board, both individually and in the context of the Board’s existing membership at the time such potential candidate is considered.
Transactions with Adams Diversified Equity Fund, Inc.
The Fund shares certain expenses for research, accounting services, other office services (including proportionate salaries and other employee benefits), rent and related expenses, and miscellaneous expenses, such as office supplies, postage, subscriptions, and travel, with ADX. These expenses were paid by ADX and, on the date the payment was made, the Fund simultaneously paid to ADX its allocated share of such expenses, based on either estimated time spent for each fund, the proportion of the size of the investment portfolios of the two funds, relative net assets of the two funds or, where possible, on an actual usage basis, in accordance with the Fund’s expense allocation policy. In 2021, the funds incurred $17,596,434 in shared expenses, and ADX’s share of such expenses was $13,901,250.
Compensation of Directors and Executive Officers
During 2021, each director who is not an interested person, except for Dr. McGahran, received an annual retainer fee of  $65,000. Dr. McGahran, the Board Chair, received an annual retainer fee of $85,000. The Chairperson of each committee received an additional annual retainer fee of  $3,000 for that committee. The total amount of fees paid to independent directors in 2021 was $511,083.

TABLE OF CONTENTS​​
Employee Thrift Plans
Employees of the Fund who have completed six months of service may defer up to 100% of base salary and cash incentive compensation to a tax qualified thrift plan (“Thrift Plan”) instead of being paid currently, and the Fund contributes an amount equal to 100% of each employee’s contribution (up to 6% of base salary and cash incentive compensation) but not in excess of the maximum permitted by law (see footnotes to the Compensation Table set forth on page 14 regarding 2021 contributions for the officers identified therein). The Fund also has the discretion to contribute annually to each employee’s thrift plan account an amount of up to 6% of the employee’s combined base salary and cash incentive compensation attributable to the prior year’s service with the Fund. All employee contributions are credited to the employee’s individual account. Employees may elect that their salary deferral and other contributions be invested in the common stock of the Fund or ADX, or a number of mutual funds, or a combination thereof. All of the Fund’s matching contribution is invested in accordance with the employee’s investment elections. An employee’s interest in amounts derived from the Fund’s contributions becomes non-forfeitable upon completion of 36 months of service or upon death or retirement. Payments of amounts not withdrawn or forfeited under the Thrift Plan may be made upon retirement or other termination of employment.
The Fund also maintains an Executive Nonqualified Supplemental Thrift Plan for eligible employees of the Fund (the “Nonqualified Plan”). The purpose of the Nonqualified Plan is to provide deferred compensation in excess of contribution limits imposed by the Internal Revenue Code on tax-qualified thrift plans, including the Thrift Plan described above. In accordance with such limitations, for 2021, the maximum annual amount that an individual can defer to the Thrift Plan is $19,500 for those under the age of 50, and $26,000 for those age 50 and over, and the maximum combined amount – consisting of both the employee’s contributions and the Fund’s matching contributions – that can go into the Thrift Plan is $58,000 per year for those under the age of 50 and $64,500 per year for those age 50 and over.
The Nonqualified Plan permits an eligible employee to contribute to the Nonqualified Plan up to the maximum amount of 6% of the employee’s salary and cash incentive compensation that he or she is prevented from contributing to the Thrift Plan because of the Internal Revenue Code’s limitations on annual contributions, and for the Fund to contribute the 100% matching contribution on that sum and/or the Fund’s discretionary contribution that would otherwise be limited by the Internal Revenue Code’s limitations on annual contributions. The employee’s contributions and the Fund’s contributions to the Nonqualified Plan are invested in eligible mutual funds in accordance with the employee’s investment elections.
Brokerage Commissions
During the past fiscal year, the Fund paid brokerage commissions in the amount of $140,259 on the purchase and sale of portfolio securities traded on the New York Stock Exchange and the National Association of Securities Dealers Automated Quotation System, and on swap transactions, substantially all of which were paid to brokers providing research and other investment services to the Fund. The average per share commission rate paid by the Fund was $0.03. No commissions were paid to an affiliated broker.
Portfolio Turnover
The portfolio turnover rate (purchases or sales, whichever is lower, as a percentage of average portfolio value) for the past three years has been as follows:

​ | 2021 | ​ | ​ | 2020 | ​ | ​ | 2019 | ​
​ | 20.7% | ​ | ​ | 31.8% | ​ | ​ | 29.5% | ​

​ | 2021 | ​ | ​ | 2020 | ​ | ​ | 2019 | ​
​ | 0.88% | ​ | ​ | 1.47% | ​ | ​ | 0.97% | ​

The Board of Directors unanimously recommends that stockholders vote FOR the election of each of the nominees for director.
(2) RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
As permitted under the Act, the Audit Committee selected PricewaterhouseCoopers LLP, 100 E. Pratt Street, Suite 2600, Baltimore, MD 21202, an independent registered public accounting firm, for recommendation to the full Board as the independent registered public accounting firm to audit the books and accounts of the Fund for the year ending December 31, 2022. PricewaterhouseCoopers LLP was the Fund’s principal auditor during the year 2021. A majority of the members of the Board of Directors who are not “interested persons” ​(as defined by the Act) have approved the selection of PricewaterhouseCoopers LLP as the Fund’s independent registered public accounting firm for 2022. While not required under the Act, the Audit Committee and the Board of Directors have determined to submit for stockholder ratification the selection of PricewaterhouseCoopers LLP as the Fund’s independent registered public accounting firm for 2022 at the Annual Meeting. Representatives of PricewaterhouseCoopers LLP are expected to be present at the meeting to make a statement, if they so desire, and to respond to appropriate questions. The Fund has been informed that PricewaterhouseCoopers LLP does not have any direct financial or any material indirect financial interest in the Fund.
Independent Accountant Fees
Audit Fees
The aggregate fees for professional services rendered by the Fund’s independent registered public accounting firm, PricewaterhouseCoopers LLP, for the audit of the Fund’s annual financial statements for 2021 and 2020 were $92,790 and $90,090, respectively.

16

TABLE OF CONTENTS​​​
The Board’s Audit Committee has considered the provision by PricewaterhouseCoopers LLP of the services covered in this All Other Fees section and found that they are compatible with maintaining PricewaterhouseCoopers LLP’s independence.
Audit Committee Pre-Approval Policy
The Audit Committee’s policy is to pre-approve all audit and permissible non-audit services provided by the independent auditors. In assessing requests for services by the independent auditors, the Committee considers whether such services are consistent with the auditor’s independence; whether the independent auditors are likely to provide the most effective and efficient service based upon their familiarity with the Fund; and whether the service could enhance the Fund’s ability to manage or control risk or improve financial statement audit and review quality. The Committee may delegate pre-approval authority to its Chair. Any pre-approvals by the Chair under this delegation are to be reported to the Committee at its next scheduled meeting. All services performed for 2021 were pre-approved by the Committee.
The Board of Directors unanimously recommends ratification of the selection of
PricewaterhouseCoopers LLP.
