CBOF-FM is a French-language Canadian radio station located in Ottawa, Ontario. CBOF's studios are located on Carling Avenue near The Queensway.

Owned and operated by the (government-owned) Canadian Broadcasting Corporation (French : Société Radio-Canada), it broadcasts on 90.7 MHz with an effective radiated power of 84,000 watts (class C1) using an omnidirectional antenna located in Camp Fortune, Quebec.

The station has an ad-free news/talk format and is part of the Ici Radio-Canada Première network, which operates across Canada.

The station signed on in 1964 on the AM band on 1250 kHz. Before then, Ottawa, despite its large francophone population, had no French-language radio outlet of its own; Radio-Canada instead relied on the 50,000-watt signal of Montreal's CBF to serve Ottawa's francophones. The station moved to the FM band in 1991. Its sister station, which used the CBOF-FM calls before that date, is now known as CBOX-FM.

While CBOF-FM broadcasts in mono, like all Première stations but unlike most FM stations, it broadcasts in mono. Briefly, CBOF, still as an AM station, experimented with AM stereo broadcasts between 1984 and 1987, testing all four AM stereo systems (C-QUAM, Kahn/Hazeltine, Harris and Magnavox) proposed at the time.

The station's current local programs are Les matins d'ici, in the mornings from 5:30 a.m. to 9 a.m., and Les voies du retour in the afternoons, 3 p.m. to 6 p.m. Its Saturday morning local program is Divines tentations, heard from 7:00 a.m. to 11 a.m.
