CCGS Louis S. St-Laurent is a Canadian Coast Guard Heavy Arctic Icebreaker. Louis S. St-Laurent's home port is St. John's, Newfoundland and Labrador and is stationed there with other vessels of the coast guard.

Named after the twelfth Prime Minister of Canada, The Right Honourable Louis St. Laurent, PC CC QC LLD DCL LLL BA. The vessel is classed a "Heavy Arctic Icebreaker" and is the largest icebreaker and flagship of the CCG.

Louis S. St-Laurent is based at CCG Base St. John's in St. John's, Newfoundland. The vessel's current operation tempo consists of summer voyages to Canada's Arctic where she supports the annual Arctic sealift to various coastal communities and carries out multi-disciplinary scientific expeditions. During the winter months, Louis S. St-Laurent sometimes operates in the Gulf of St. Lawrence to aid ships in transiting to Montreal, Quebec, although she usually only serves this assignment during particularly heavy ice years.

Louis S. St. Laurent was launched 3 December 1966 by Canadian Vickers Limited at Montreal, Quebec and commissioned in October 1969.

From 8–22 September 1969 Louis S. St-Laurent sailed on the SS Manhattan expedition in the Northwest Passage. She was assisted by CCGS John A. Macdonald and the United States Coast Guard vessels USCGC Northwind and USCGC Staten Island
