Jääkarhu was a Finnish and later Soviet steam-powered icebreaker. Built in 1926 by P. Smit Jr. Shipbuilding and Machine Factory in Rotterdam, Netherlands, she was the last and largest steam-powered state-owned icebreaker of Finland. After two decades of successful service, Jääkarhu was handed over to the Soviet Union as war reparation in 1945 and renamed Sibiryakov. She remained in service until the 1970s and was broken up in 1972.
