The 1912–13 season was the 36th Scottish football season in which Dumbarton competed at national level, entering the Scottish Football League, the Scottish Cup and the Scottish Qualifying Cup.
See main article: 1912–13 Scottish Football League. Dumbarton's seventh successive season in the Second Division saw their worst performance since their return to league football in 1906, but still managed a 6th place finish with 29 points, 5 behind champions Ayr United.[1]
An expansion of the First Division from 18 to 20 clubs meant that there would be at least 2 places available to Second Division clubs in the end of season election. As it was both the bottom 'top flight' clubs - Partick Thistle and Queen's Park - were to retain their places, and in addition to Ayr United, the Second Division champions, it was Dumbarton that would step up to the First Division - beating Cowdenbeath with the chairman's casting vote.
See main article: 1912–13 Scottish Cup. The Scottish Cup campaign saw Dumbarton disposing of First Division opponents before losing to eventual champions Falkirk in the fourth round.
Dumbarton qualified for the Scottish Cup by reaching the semi-final of the Scottish Qualifying Cup before losing to non-league Nithsdale Wanderers.
During the season, 3 'friendly' matches were played, winning 1, drawing 1 and losing 1, scoring 4 goals and conceding 4.
