CKNC is a former Canadian television station, which broadcast in Greater Sudbury, Ontario. It was a private affiliate of the Canadian Broadcasting Corporation, through Northern Ontario's MCTV television system.

CKNC was established on October 4, 1971 by J. Conrad Lavigne, the owner of CFCL in Timmins. On the same day, the existing television station in Sudbury, CKSO, switched affiliation to CTV and adopted the new call letters CICI.

Until 1980, CICI and CKNC aggressively competed with each other for advertising dollars, leaving both in a precarious financial position due to the Sudbury market's relatively small size. In 1980, the Canadian Radio-television and Telecommunications Commission approved the merger of the two stations, along with their co-owned stations in North Bay and Timmins, into the MCTV twinstick.

In 1990, the stations were acquired by Baton Broadcasting. Baton subsequently sold CKNC to the CBC in 2002; the station is now a semi-satellite of CBLT in Toronto.
