Bergsøy Idrettslag is a Norwegian multi-sports club from Fosnavåg, Møre og Romsdal.
The club was founded at Bergsøya on 4 October 1944, as Bergsøy Turn- og Atletklubb.
The club also arranged its first skiing competition in February 1945, despite Norway still being occupied by Germany.
After the occupation ended, the name was changed to Bergsøy Idrettslag, and the expansion of sports and facilities started.
After a successful 2002 season the team contested a playoff for promotion to the Second Division, but lost to Averøykameratene.
