1977 British League season

The 1977 Gulf British League season was the thirteenth season of the highest tier of motorcycle speedway in Great Britain. Newport had dropped down to the National League but their riders transferred to the Bristol Bulldogs so the league retained 19 teams. Cradley Heath reverted to their nickname of Heathens after four years of being called United. The league was sponsored by Gulf Oil for a third season. White City Rebels won the title in only their second season of existence.
