Murtaja was a Finnish state-owned steam-powered icebreaker. Built in 1890 by Bergsunds Mekaniska Verkstads AB in Stockholm, Sweden, she was the first state-owned icebreaker of Finland and one of the first purpose-built icebreakers in the world. Murtaja remained in service for 68 years until she was decommissioned and broken up in 1958 after having been replaced by the diesel-electric Karhu.
