This was the fourth season of war-time football, where the playing of all national competitions, other than the Scottish League, was suspended.

Membership of the League was reduced from 20 to 18, with Aberdeen, Dundee and Raith Rovers withdrawing and Clydebank being admitted.

Dumbarton retained the Dumbartonshire Charity Cup for the second successive year by beating Renton in the final.

During the season two charity matches were played for the benefit of the Red Cross War Fund, both being won, scoring 8 goals for the loss of 4.
