CKOF-FM is a French-language Canadian radio station located in Gatineau, Quebec (near Ottawa, Ontario). Owned and operated by Cogeco, it broadcasts on 104.7 MHz from facilities in the Chemin des Terres neighbourhood of Gatineau, while its transmitter is located in Camp Fortune. The station identifies itself as "104,7 FM".

The station originally began broadcasting in 1968 as CJRC, on 1150 kHz with a daytime power of 50,000 watts and a nighttime power of 5,000 watts as a class B station, using a directional antenna with slightly different daytime and nighttime directional patterns in order to protect various other stations on that frequency – particularly CKOC in Hamilton.

The station was launched on June 3, 1968 by Raymond Crepeau, Marcel Joyal, Robert Campeau and Gerard Moreau with the presence of Pierre Elliott Trudeau, the former prime minister of Canada as part of the Radiomutuel network. Originally its headquarters were at the Sparks Street Mall in Ottawa but were later moved in the old city of Gatineau in the 1980s after a stay on Belfast Road in Ottawa. It became part of the Radiomédia network (later known as Corus Québec) on September 30, 1994, after Radiomutuel merged with Télémédia (that network's Gatineau station, CKCH, was closed down).

On November 24, 2006, the CRTC authorized the station to switch to the FM band. The change of frequency forced CHMY's transmitter in Arnprior, formerly on 104.7, to move to 107.7 FM.
