KFXD (630 kHz) is a commercial AM radio station licensed to serve Boise, Idaho. The station is owned by Townsquare Media. It airs a sports format using the name "Sports Radio 630 The Fan" using programming from Fox Sports Radio.
The station was assigned the KFXD call letters by the Federal Communications Commission on August 14, 2002.
On October 15, 2008, KFXD's talk radio lineup was absorbed by sister station 580 KIDO as the two stations began to simulcast, with 580 based in Nampa, Idaho and 630 based in Boise. In October 2011 KFXD changed its format to sports, branded as "630 The Fan". Then owned by Peak Broadcasting, KFXD later lost the rights to broadcast Boise State Broncos athletics, to rival AM station 670 KBOI.
On August 30, 2013, a deal was announced in which Townsquare Media would purchase Peak Broadcasting's stations, including KFXD. The deal is part of Cumulus Media's acquisition of Dial Global; Townsquare will swap Peak's Fresno, California stations to Cumulus for its stations in Dubuque, Iowa and Poughkeepsie, New York, and Peak, Townsquare, and Dial Global are all controlled by Oaktree Capital Management. The sale to Townsquare was completed on November 14, 2013.
