CBF-FM-8 is a French-language Canadian radio station located in Trois-Rivières, Quebec.

Owned and operated by public broadcaster Canadian Broadcasting Corporation as part of the French-language Société Radio-Canada system, it broadcasts on 96.5 MHz using a directional antenna with an average effective radiated power of 66,700 watts and a peak effective radiated power of 100,000 watts (class C1).

The station has an ad-free news/talk format and is part of the Ici Radio-Canada Première network, which operates across Canada. Like all Première stations, but unlike most FM stations, it broadcasts in mono.

The station signed on in 1977 as a full-time rebroadcaster of CBF in Montreal. Before then, Radio-Canada programming had aired on private affiliate CHLN. However, despite Trois-Rivières' large size, the CBC opted not to open a full-fledged station in the city. It became a separately licensed station in 2000, while retaining a rebroadcaster-like callsign.

The station's current local programs are Facteur matinal from 6 a.m. to 9 a.m. and 360 PM in the afternoons from 3:30 p.m. to 6 p.m. On public holidays, its local programs are replaced with local shows airing provincewide (Quebec) produced by different outlets in turn (except Montreal and Quebec City). The Saturday morning program, Samedi et rien d'autre, originates from CBF-FM.

CBF-FM-8 was originally on 100.1 MHz, and moved to 88.1 MHz in 1985. It moved to its current frequency at 96.5 MHz in late 2003.
