Hammarby IF Ishockeyförening, commonly known as Hammarby Hockey, is a Swedish ice hockey club originally founded in 1921 and based in Stockholm. They were giants in the early history of Swedish hockey, playing in the domestic top league from the birth of Swedish organized hockey in 1922 until 1957. During that period, they were crowned Swedish champions eight times (1932, 1933, 1936, 1937, 1942, 1943, 1945, and 1951) in 13 attempts. The rest of their history has been more modest, having qualified for play in Elitserien (Sweden's current top-tier league, now called the SHL) only twice.
