CNC3 Television (CNC3) is a television station privately owned by Guardian Media Limited serving Trinidad and Tobago. It broadcasts over-the-air on channels 12 and 14 and is seen throughout the Flow cable system on channel 3. CNC3's studios are located at the Trinidad Guardian building located on 22-24 St. Vincent Street, Port of Spain, Trinidad and Tobago.

The acronym CNC3 originally stood for Cable News Channel 3, as the station was originally a news and current affairs themed channel which was carried on channel 3 on the Flow national cable service. When the station went free-to-air, the name CNC3 was retained, but the focus shifted from exclusively news programming to include general entertainment and movies as well.

CNC3 broadcast begun on 26 September 2005. Approximately three hours prior to the station's debut, the Telecommunications Authority of Trinidad and Tobago (TATT) ordered that CNC3 not proceed with its broadcasts claiming the broadcaster had no authority to proceed. TATT reversed its decision late the following day, and broadcasts began shortly thereafter.
