CKFX-FM is a Canadian radio station, which broadcasts at 101.9 FM in North Bay, Ontario. The station airs an active rock format under the brand name 101.9 The Fox. Despite being branded differently, the station uses the same general format as — and shares some programming with — its Q92 sister stations CJRQ-FM in Sudbury and CJQQ-FM in Timmins.

The station was originally launched in Iroquois Falls in 1922, as CFCH, a corporate communications service for lumber camps owned by Abitibi Power and Paper Company. It was subsequently acquired by Roy Thomson in 1930, and moved to North Bay. The station originally launched in North Bay at 930 on the AM dial, moving to 1230 in 1941 and then to 600 in 1942. CFCH was on the FM dial at 106.3 MHz for a brief period in the 1940s and 1950s. The 106.3 MHz frequency is now occupied by CFXN-FM.

In 1960, Thomson's Northern Broadcasting acquired the city's television station, CKGN, which also adopted the CFCH callsign. In 1976, Northern also acquired the FM station CKAT. Thomson subsequently sold Northern Broadcasting to a local business consortium in 1974. In 1980, the stations were sold to Telemedia.
