CFNS may refer to:
- CFNS (AM), a defunct radio station in Saskatoon, Saskatchewan,

CFNS was a Canadian radio station, which broadcast in Saskatoon, Saskatchewan from 1952 to 1973. A private affiliate of Radio-Canada, the station was owned by Radio-Prairies-Nord Ltée.
CFRG originally aired at 1170 AM. The station was purchased by Radio-Canada in 1973, and became a rebroadcaster of Regina's CBKF-FM. A few months later, it moved to AM 860. The transmitter, which now has the call sign CBKF-2, is still in operation as a rebroadcaster of CBKF.
