The 1975 Gulf Oil British League season was the 41st season of the top tier of motorcycle speedway in the United Kingdom and the 11th season known as the British League.

Summary

The league was sponsored for the first time by Gulf Oil. Reading Racers returned after a one-season absence to increase the size of the league back to eighteen teams and the ban on overseas riders that rode in other leagues abroad was lifted. The Ipswich Witches won their first title, defeating Belle Vue Aces by a solitary point. John Louis and Billy Sanders scored heavily throughout the season for Ipswich. Belle Vue found consolation by winning the Knockout Cup. In their last season at the Cowley track, Oxford Rebels won the Midland Cup, beating Wolverhampton Wolves but the competition was overshadowed by the death of rider Gary Peterson.
