Re:  Registration Statement on Form N-2

Ladies and Gentlemen:

We have acted as counsel to Nuveen Municipal Income Fund, Inc. (the “Fund”), a Minnesota corporation, in connection with the registration of two million shares of common stock, $0.01 par value per share (“Common Stock”) and subscription rights to purchase Common Stock (“Rights,” and collectively with Common Stock, “Securities”), pursuant to a registration statement on Form N-2 to be filed on or about the date hereof (the “Registration Statement”) with the U.S. Securities and Exchange Commission under the Investment Company Act of 1940 (the “Investment Company Act”) and the Securities Act of 1933 (the “Securities Act”).

This opinion is furnished in accordance with the requirements of Item 25.2(l) of Form N-2 under the Investment Company Act and the Securities Act.

In this connection, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such documents, corporate and other records, certificates and other papers as we deemed it necessary to examine for the purpose of this opinion, including the Fund’s Articles of Incorporation (the “Articles of Incorporation”) and Amended and Restated By-Laws (the “By-Laws”), actions of the Board of Trustees of the Fund (the “Board”) authorizing the registration of the Securities, and the Registration Statement.

In our examination, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as facsimile, electronic, certified, conformed or photostatic copies and the authenticity of the originals of such copies. As to any facts material to the opinions expressed herein that we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of the Fund and others.

We have assumed the following for purposes of this opinion:

1.  The Securities will be issued in accordance with the Articles of Incorporation and By-Laws, each as is in existence as of the date of this opinion, and that the Board will take all

actions and pass all resolutions necessary to authorize, issue and sell the Securities, and that the specific terms of the Securities will be determined in accordance with all Board resolutions.

2.  The Securities will be issued against payment therefor as described in the Prospectus, including the applicable Prospectus Supplement, and the Statement of Additional Information relating thereto included in the Registration Statement.

Based upon the foregoing, we are of the opinion that when the Securities are issued and sold after the Registration Statement has been declared effective and the authorized consideration therefor is received by the Fund, (i) any Rights so issued and sold will be a binding obligation of the Fund under the laws of Minnesota, and (ii) any Common Stock, including those Common Stock underlying Rights, so issued and sold will be legally issued, fully paid and non-assessable by the Fund, except that, as set forth in the Registration Statement, shareholders of the Fund may under certain circumstances be held personally liable for obligations of the Fund.

In rendering the foregoing opinion, we have relied upon the opinion of Dorsey & Whitney LLP expressed in their letter to us dated April 29, 2024.

We hereby consent to the use of this opinion as an exhibit to the Registration Statement of the Fund and we further consent to reference in the Registration Statement of the Fund to the fact that this opinion concerning the legality of the issue has been rendered by us.

Very truly yours,

/s/ Stradley Ronon Stevens & Young, LLP
