Voima is a Finnish state-owned icebreaker. Built by Wärtsilä Hietalahti shipyard in Helsinki in 1954, she was the first icebreaker in the world to be equipped with two bow propellers and generated widespread publicity that helped the Finnish shipbuilding industry to become the world leader in icebreaker design.
Voima was extensively refitted in 1978–1979. As of 2024, she is the oldest and smallest state-owned icebreaker in service in Finland. Originally, Voima was scheduled to be replaced by a new icebreaker by the winter of 2015–16. However, in 2016 it was decided to extend her operational lifetime by at least ten years with another refit.
