Exhibit 99.(r)(i)

CENTER COAST MLP & INFRASTRUCTURE FUND

CODE OF ETHICS

Adopted Under Rule 17j-1

While affirming its confidence in the integrity and good faith of all of its officers and trustees, Center Coast MLP & Infrastructure Fund (the “Fund”), recognizes that the knowledge of present or future portfolio transactions and, in certain instances, the power to influence portfolio transactions which may be possessed by certain of its officers, employees and trustees could place such individuals, if they engage in personal transactions in securities which are eligible for investment by the Fund, in a position where their personal interest may conflict with that of the Fund.

In view of the foregoing and of the prohibitions of Rule 17j-1(b) under the Investment Company Act of 1940 (the “1940 Act”), the Fund has determined to adopt this Code of Ethics to specify and prohibit certain types of transactions deemed to create conflicts of interest (or at least the potential for or the appearance of such a conflict), and to establish reporting requirements and enforcement procedures.

I. Statement of General Principles.

In recognition of the trust and confidence placed in the Fund by its shareholders, and to give effect to the Fund’s belief that its operations should be directed to the benefit of its shareholders, the Fund hereby adopt the following general principles to guide the actions of its trustees, officers and employees.

(1) The interests of the Fund’s shareholders are paramount, and all of the Fund’s personnel must conduct themselves and their operations to give maximum effect to this tenet by assiduously placing the interests of the shareholders before their own.

(2) All personal transactions in securities by the Fund’s personnel must be accomplished so as to avoid even the appearance of a conflict of interest on the part of such personnel with the interests of the Fund and its shareholders.

(3) All of the Fund’s personnel must avoid actions or activities that allow (or appear to allow) a person to profit or benefit from his or her position with respect to the Fund, or that otherwise bring into question the person’s independence or judgment.

II. Definitions.

(1) “Access Person” shall mean (i) each Trustee or officer of the Fund or its Advisor, (ii) each employee of the Fund or its Advisor (or of any company in a control relationship to the Fund) who, in connection with his or her regular functions or duties, makes, participates in, or obtains information regarding the purchase or sale of a security by the Fund or any series thereof, or whose functions relate to the making of any recommendations with respect to such purchases or sales, (iii) any natural person in a

control relationship to the Fund or its Advisor who obtains information concerning recommendations made to or by the Fund with respect to the purchase or sale of a security, or whose functions relate to the making of any recommendations with respect to such purchases or sales; (iv) each director, officer or general partner of any principal underwriter for the Fund, but only where such person in the ordinary course either makes, participates in, or obtains information regarding the purchase or sale of Securities, or whose functions relate to the making of recommendations regarding securities; and (v) any natural person in a control relationship who obtain information concerning recommendations made with regard to the purchase or sale of a security.

(2) “Beneficial ownership” of a security is to be determined in the same manner as it is for purposes of Section 16 of the Securities Exchange Act of 1934. This means that a person should generally consider him the beneficial owner of any securities in which he has a direct or indirect pecuniary interest. In addition, a person should consider himself the beneficial owner of securities held by his spouse, his minor children, a relative who shares his home, or other persons by reason of any contract, arrangement, understanding or relationship that provides him with sole or shared voting or investment power.

(3) “Control” shall have the same meaning as that set forth in Section 2(a)(9) of the 1940 Act. Section 2(a)(9) provides that “control” means the power to exercise a controlling influence over the management or policies of a company, unless such power is solely the result of an official position with such company. Ownership of 25% or more of a company’s outstanding voting securities is presumed to give the holder thereof control over the company. Such presumption may be countered by the facts and circumstances of a given situation.

(4) “Independent Trustee” means a trustee of the Fund who is not an “interested person” of the Fund within the meaning of Section 2(a)(19) of the 1940 Act.

(5) “Initial Public Offering” (“IPO”) means an offering of Securities registered under the Securities Act of 1933, the issuer of which, immediately before registration, was not subject to the reporting requirements of Section 13 or Section 15(d) of the Securities Exchange Act of 1934.

(6) “Portfolio Manager” means an individual who is involved in making the purchase or sale decisions of securities for the Fund.

(7) “Private Placement” means an offering that is exempt from registration under the Securities Act of 1933 pursuant to Section 4(2) or Section 4(6) of the Securities Act of 1933 or pursuant to Rules 504, 505 or 506 under the Securities Act of 1933.

(8) “Special Purpose Investment Personnel” means each Access Person who, in connection with his or her regular functions (including, where appropriate, attendance at Board meetings and other meetings at which the official business of the Fund is discussed or carried on), obtains contemporaneous information regarding the purchase or sale of a security by the Fund. Special Purpose Investment Personnel shall occupy this

status only with respect to those securities as to which he or she obtains such contemporaneous information.

(9) “Purchase or sale of a security” includes, among other things, the writing of an option to purchase or sell a security.

(10) “Review Officer” means the officer of the Fund or the Advisor designated from time to time to receive and review reports of purchases and sales by Access Persons. It is recognized that a different Review Officer may be designated with respect to the Fund and the Advisor.

(11) “Security” shall have the same meaning as that set forth in Section 2(a)(36) of the 1940 Act, except that it shall not include direct obligations of the Government of the United States, bankers’ acceptances, bank certificates of deposit, commercial paper, shares issued by registered, open-end mutual funds (other than exchange-traded funds) and high quality short-term debt instruments, including repurchase agreements.

(12) A Security “held or to be acquired” by the Fund means (A) any Security which, within the most recent 15 days, (i) is or has been held by the Fund thereof, or (ii) is being or has been considered by the Fund’s Advisor for purchase by the Fund; (B) and any option to purchase or sell and any Security convertible into or exchangeable for any Security described in (A) above.

(13) A Security is “being purchased or sold” by the Fund from the time when a purchase or sale program has been communicated to the person who places the buy and sell orders for the Fund until the time when such program has been fully completed or terminated.

III. Prohibited Purchases and Sales of Securities.

(1) No Access Person shall, in connection with the purchase or sale, directly or indirectly, by such person of a Security held or to be acquired by the Fund:

(A) employ any device, scheme or artifice to defraud the Fund;

(B) make to the Fund any untrue statement of a material fact or omit to state to the Fund a material fact necessary in order to make the statements made, in light of the circumstances under which they are made, not misleading;

(D) engage in any manipulative practice with respect to the Fund.

(2) No Portfolio Manager may purchase or sell, directly or indirectly, any Security in which he had (or by reason of such transaction acquires) any Beneficial

Ownership at any time within seven (7) calendar days before or after the time that the same (or a related) Security is being purchased or sold by the Fund.

(3) No Special Purpose Investment Personnel may profit in the purchase and sale, or sale and purchase of a Security as to which he or she is a Special Purpose Investment Personnel within 60 days of acquiring or selling Beneficial Ownership of that Security.

IV. Additional Restrictions and Requirements

(1) Pre-approval of Private Placements & IPOs — Special Purpose Investment Personnel must obtain approval from the Review Officer before acquiring beneficial ownership of any securities offered in connection with an IPO or a Private Placement.

The information in such report shall be current as of a date no more than 45 days prior to the date the person becomes an Access Person. Such report shall include:

(A) The title, number of shares and principal amount of each Covered Security in which the Access Person had any direct or indirect beneficial ownership when the person became an Access Person;

(2) Each Access Person (other than the Fund’s Independent Trustees) shall report all transactions in Securities in which the person has, or by reason of such transaction acquires, any direct or indirect Beneficial Ownership. Reports shall be filed with the Review Officer quarterly. The Review Officer shall submit confidential quarterly reports with respect to his or her own personal securities transactions to an officer designated to receive his or her reports (“Alternate Review Officer”), who shall act in all respects in the manner prescribed herein for the Review Officer.

(The “should have known” standard implies no duty of inquiry, does not presume there should have been any deduction or extrapolation from discussions or memoranda dealing with tactics to be employed meeting the Fund’s investment objectives, or that any knowledge is to be imputed because of prior knowledge of the Fund’s portfolio holdings, market considerations, or the Fund’s investment policies, objectives and restrictions.)

(7) Any such report may contain a statement that the report shall not be construed as an admission by the person making such report that he has any direct or indirect beneficial ownership in the security to which the report relates.

(8) Each Independent Trustee shall report the name of any publicly-owned company (or any company anticipating a public offering of its equity securities) and the total number of its shares beneficially owned by him or her if such total ownership is more than 1/2 of 1% of the company’s outstanding shares. Such report shall be made promptly after the date on which such Independent Trustee’s ownership interest equaled or exceeded 1/2 of 1%.

VI. Review and Enforcement.

(1) The Review Officer shall compare all reported personal securities transactions with completed portfolio transactions of the Fund and a list of securities being considered for purchase or sale by the Fund’s Advisor to determine whether a violation of this Code may have occurred. Before making any determination that a violation has been committed by any person, the Review Officer shall give such person an opportunity to supply additional explanatory material.

(2) If the Review Officer determines that a violation of this Code may have occurred, he shall submit his written determination, together with the confidential monthly report and any additional explanatory material provided by the individual, to the President of the Fund and outside counsel, who shall make an independent determination as to whether a violation has occurred.
