WMRN-FM (94.3 MHz) is a country music radio station in Marion, Ohio, currently owned by iHeartMedia.

Originally owned by Scantland Communications, who also owned WQEL-FM (92.7 Bucyrus, Ohio), featured an eclectic format of soft jazz and adult contemporary hits as well as newscasts produced by a 3-person news department.

The call letters reflected the station's slogan, "WDIF Makes a Difference."

The company also tried to purchase WMRN-AM, WDIF-FM, WMRN-FM, WBUK-FM and WPFX-FM but the sale was not approved by the Department of Justice because of ownership limits in the concentrated Mid-Ohio market.

Burbach then sold the stations to Randy Michaels-led Jacor Communications, based in Cincinnati, Ohio.
