The 1976–77 Southern Football League season was the 74th in the history of the league, an English football competition. It was the first Southern Football League season to use goal difference as a tie-breaker. Wimbledon won the championship, winning their third Southern League title in a row and was elected to the Football League replacing Workington, whilst Worcester City, Barnet, Cheltenham Town and Hastings United were all promoted to the Premier Division, the former two as champions. Metropolitan Police left the league to join the Isthmian League.
