Tarmo is a Finnish steam-powered icebreaker preserved in the Maritime Museum of Finland in Kotka. Built in 1907 by Sir W.G. Armstrong, Whitworth & Co Ltd in Newcastle upon Tyne, United Kingdom, she was the third state-owned icebreaker of Finland and the last Finnish steam-powered icebreaker to remain in service. When Tarmo was decommissioned in 1970, a decision was made to preserve the vessel as a museum ship. After a long wait in Helsinki, Tarmo was towed to Kotka and completely restored in the early 1990s.
