CBFX-FM is a French-language Canadian radio station located in Montreal, Quebec.

Owned and operated by the public broadcaster the Canadian Broadcasting Corporation (French: Société Radio-Canada), it broadcasts on 100.7 MHz from the Mount Royal candelabra tower with an effective radiated power of 100,000 watts (class C1) using an omnidirectional antenna. Its studios and master control are located at Maison Radio-Canada in Montreal.

It is the flagship of the Ici Musique network (previously known, from 2004 to 2014 as Espace musique; and before September 2004, as La Chaîne culturelle when the format was more focused on classical music), which operates across Canada. The station has an ad-free music format featuring mostly classical music, jazz, world music and also other genres.

The station began experimental broadcasts on March 13, 1946 as VE9CB on 98.1 FM. It received a full license on March 5, 1948 as CBF-FM on 95.1 FM. It swapped frequencies with CBM-FM in 1971, moving to 100.7. This move not only allowed it to boost its signal to a full 100,000 watts, but allowed it to broadcast in stereo for the first time. Originally a straight simulcast of CBF AM, it became the flagship of Radio-Canada's FM network, Chaîne culturelle, at its launch in 1972. It adopted its current calls in 1998 when its AM sister moved to the FM band and picked up the CBF-FM calls.

1 - On April 25, 2013, the CRTC approved the CBC's application to amend the licenses of CBFX's rebroadcasters at Trois-Rivières and Sherbrooke, with both stations broadcasting at least 20 minutes of local programming each week, with the remainder programming from the Espace Musique network. The Trois-Rivières repeater at 104.3 MHz will upgrade to an average ERP of 45,400 watts, and a maximum ERP of 100,000 watts (up from 43,000 watts max ERP currently) with an effective height above average terrain of 249.7 metres. The Sherbrooke transmitter at 90.7 MHz will keep its existing parameters with an ERP of 25,000 watts (non-directional antenna with an EHAAT of 173 metres).[1]

Though CBFX-4 and CBFX-5 are technically rebroadcasters of CBFX, on-air idents show they actually rebroadcast Ottawa's CBOX-FM.
