The South Devon Football League, known under a sponsorship arrangement as the TCSSDFL, is a football competition based in England. Its top division, the Premier Division, sits outside of the English football league system although it is a feeder to the Devon Football League which sits at Step 11 of this system. There are five divisions in the league. The SDFL's primary cup competition is the Herald Cup, which is a simple knockout competition featuring all SDFL clubs (highest placed teams only). Following the formation of the East Devon FA in 1903, the league came into existence as the Torquay and District League for the 1903–04 season. The first winners were Ellacombe. The league changed its name to the South Devon League for the 1920–21 season.
