The Combined Reserve Football League was formed in 1958 as a reserve football league for the Scottish Football League Second Division sides that were excluded from the Scottish Reserve Football League. The original five clubs were Albion Rovers 'A', Dumbarton 'A', Morton 'A', Queen's Park Strollers plus Celtic's third eleven. Because of the small number of clubs involved, the league was normally played over an autumn and spring series. Another aspect of the league's membership was the frequent inclusion of non-league clubs.

Although the league disbanded in 1972, its name was resurrected by the Scottish League for its minor reserve sides.
