CKSH-DT is a television station in Sherbrooke, Quebec, Canada. It is an owned-and-operated station of the Radio-Canada network in the Estrie region.

The station first aired on September 19, 1974. As a privately owned station, CKSH basically functioned as a semi-satellite of CBFT in Montreal due to not having alternative non-network sources of programming available. The station had been owned directly by Cogeco prior to the latter's majority acquisition of TQS (now V), to which Cogeco contributed its existing local stations. Radio-Canada took editorial control of the station's news programming in 2002, although it currently shares a studio with former TQS sister station CFKS-DT.

CKSH is seen on cable television systems throughout New England, serving the French American community. It serves as a vital link to the Québécois culture in these communities.

In September 2007, Radio-Canada announced that it would not renew its affiliation agreement with its three Cogeco-owned affiliates — CKSH, CKTM-TV in Trois-Rivières and CKTV-TV in Saguenay — after their then-current agreement expired in August 2008. An application to directly acquire the station was filed by Radio-Canada on April 25, 2008, concurrently with Cogeco's proposed sale of TQS to Remstar Corporation. The transaction was approved by the CRTC on June 26, 2008.
