Helsingfors Skridskoklubb (in Swedish, HSK), in Finnish Helsingin Luistinklubi, is the oldest figure skating club in Finland. It was founded in Helsinki in 1875. When spoken in Finnish, the Swedish name is, however, more common than the Finnish, the only abbreviation used is HSK.
HSK had a successful ice hockey team during the 1930s which won the SM-sarja twice (1933 & 1934). The Ice hockey team ceased to exist in early 1950s.
