WKFR-FM (103.3 MHz), also known as KFR, is a top 40 (CHR) outlet serving the Kalamazoo, Michigan, US radio market. It broadcasts with an ERP of 50 kW from Battle Creek, Michigan, and is owned by Townsquare Media.

The station began operations in June 1963 as WELL-FM at 96.5 MHz, duplicating the programming of then-sister WELL/1400 (now WBFN). In 1964, WELL-AM-FM became WKFR-AM-FM; the AM station became Top 40 rocker "Keener 14" while the FM station, which also moved to 103.3 Megahertz, programmed Beautiful Music. In 1972, WKFR changed its calls to WKNR after those calls were dropped by the former WKNR in Detroit, but the FM station remained WKFR-FM. By the end of the 1970s, WKFR-FM had evolved from "good music" to an adult contemporary format. In 1981, WKFR finally inherited the Top 40 format from WKNR and has retained it ever since.

On August 30, 2013, a deal was announced in which Townsquare Media would acquire 53 Cumulus Media stations, including WKFR-FM, for $238 million. The deal was part of Cumulus' acquisition of Dial Global; both Townsquare and Dial Global controlled by Oaktree Capital Management. The sale was consummated on November 14, 2013.
