The CCGS N.B. McLean was a Canadian Coast Guard icebreaker. Constructed in 1930 at Halifax Shipyards, she was commissioned as CGS N.B. MacLean and served in the Department of Transport's Marine Service, using the prefix "Canadian Government Ship". She was transferred into the newly created Canadian Coast Guard in 1962. She served in the St. Lawrence River and Gulf of St. Lawrence until she was decommissioned in 1979, and taken to Taiwan to be scrapped in 1989. She was replaced by CCGS Pierre Radisson.
