WIRK (103.1 FM) is a radio station broadcasting a country music format. Licensed to Indiantown, Florida, the station serves the West Palm Beach-Boca Raton, Ft. Pierce-Stuart area. The station is currently owned by Palm Beach Broadcasting, LLC. The station has broadcast a country format since September 9, 1973, originally on 107.9 FM. On April 10, 2012 CBS Radio announced that it was selling WIRK and its sister stations to Palm Beach Broadcasting for $50 million, pending FCC approval. The station's country format and airstaff will be retained under the new owners.

Prior to the country format, WIRK programmed an automated format known as “Olde Gold.” In the opening days of the format, the station was visited by country stars that included Archie Campbell, an actor who played the barber on “Hee Haw”, and by Red Sovine shortly before his death.
