In what was the last Scottish football season to be played under wartime conditions, the League competition was split into two divisions, with Dumbarton playing in Division B. Dumbarton finished 8th out of 16 with 26 points - 18 behind champions Dundee.

The story in the League Cup South was a familiar one, with Dumbarton failing to qualify from their section games.

As in 1919, a special Victory Cup was played for, but for Dumbarton there was a first round exit, to Airdrie.

The Stirlingshire Cup competition was re-established for the first time since 1939, with Dumbarton falling at the semi-final stage to A Division opponents, Falkirk.
