CCGS Teleost is a Canadian Coast Guard fisheries research vessel. The ship was originally constructed in Norway in 1988 as a commercial fishing trawler named Atlantic Champion. In 1993, the Canadian government purchased the vessel and after a competition among schoolchildren, the vessel was named Teleost by the winner. The vessel was converted to an offshore fisheries research vessel in 1994–1995 and entered service in 1996 with the Canadian Coast Guard. The ship is currently in active service.
