The 1953 Southern League was the second season of the regional third tier of speedway racing in the United Kingdom for Southern British teams. It was the final season before being replaced by the Southern Area League. From the previous season, Aldershot Shots dropped out, Wolverhampton Wasps moved up and Oxford Cheetahs came down to replace them.
Rayleigh Rockets were champions for a second consecutive season whilst Cardiff Dragons withdrew mid-season.  The title was a source of continual disputes between Rayleigh Rockets and Exeter Falcons which resulted in 2 matches between the sides won by Exeter Falcons being declared void.
