The İzmir Football League (Turkish: İzmir Futbol Ligi) was founded as a regional football league for İzmir based clubs in 1924. In the period from 1924 to 1935, the winners of the İzmir League qualified for the former Turkish Football Championship. In 1937 the first national league in Turkish football was introduced. The top two placed teams of the İzmir League qualified for the National Division, which took place after the conclusion of the regional leagues each season. The name of the league was changed later and became İzmir Professional Football League in the 1955–56 season, when professional football was introduced.

The league continued to be played after 1959, though it was no longer a first level competition since the professional nationwide league was introduced in 1959. Altay are the most successful club in league history, having won a record 14 championship titles.
