Re:	Nationwide Mutual Funds (“Registrant”)
	Rule 497(j) filing

Ladies and Gentlemen:

Pursuant to Rule 497(j) under the Securities Act of 1933, this letter serves as certification that the forms of Prospectuses and Statements of Additional Information that would have been filed under paragraph (c) of Rule 497 would not have differed from those contained in Post-Effective Amendment Nos. 263/265 (the “Amendment”) to the Registration Statement of the Registrant, which was electronically filed with the U.S. Securities and Exchange Commission on February 19, 2020. It is proposed that the Amendment will become effective on February 28, 2020.

Please direct questions or comments relating to this filing to me at the above-referenced telephone.

Very truly yours,

/s/ Jessica D. Burt
