The Southern League Cup was a regional Scottish football competition held during the Second World War, due to the suspension of national competitions. Held between 1940 and 1946, the competition involved all teams from the Southern League and was played as four groups of four with the group winners forming the semi-finals. In the final season, due to additional teams, the competition doubled in size with quarter-finals for the eight group winners. As the war ended, regular league football returned in 1946, with the regional leagues and cups disbanded.
