CCGS Alexander Henry is a former Canadian Coast Guard Light icebreaker and Buoy tender in the Great Lakes. She is currently a museum ship preserved at the Marine Museum of the Great Lakes in Kingston, Ontario. During the summer months it is also operated as a bed and breakfast.
Built at Port Arthur Shipbuilding Co. Ltd., Port Arthur, she was commissioned into the Department of Transport's Marine Service as CGS Alexander Henry using the prefix "Canadian Government Ship". She was transferred in 1962 to the newly-created Canadian Coast Guard and is named after Alexander Henry the elder, an 18th century British explorer and fur trader.
CCGS Alexander Henry served her entire coast guard career on the Great Lakes. She was launched in 1958, commissioned in 1959, and retired from service in 1984 after CCGS Samuel Risley entered service.
The Alexander Henry is scheduled to enter Kingston's historic drydocks in 2010.
