Moskva (Russian: Москва; literally: Moscow) was a Soviet polar icebreaker and the lead ship of a series of five diesel-electric icebreakers named after major Soviet cities. She was built at Wärtsilä Hietalahti shipyard in Helsinki, Finland, in 1959 and when delivered was the largest and most powerful non-nuclear icebreaker ever built. Shortly after the dissolution of the Soviet Union, Moskva was decommissioned after a long and successful career along the Northern Sea Route and sold for scrap in 1992.
