The 1966–67 season was the 83rd football season in which Dumbarton competed at a Scottish national level, entering the Scottish Football League, the Scottish Cup and the Scottish League Cup. In addition Dumbarton competed in the Stirlingshire Cup.
See main article: 1966–67 Scottish Football League. This was to be an uninspiring league season from the start, with only two wins achieved by December, and which ultimately saw Dumbarton finish in 14th place, with 33 points, a massive 36 behind champions Morton.
See main article: 1966–67 Scottish League Cup. In the League Cup, there was little to cheer with only a single win and a draw from the six sectional matches which meant no further progress in the competition.
See main article: article and 1966–67 Scottish Cup. In the Scottish Cup, after a win over local rivals Clydebank in the second preliminary round, Dumbarton fell to Division 1 opponents Partick Thistle in the first round proper.
Dumbarton's bad luck in the Stirlingshire Cup continued to 'dog' them. A first round draw against Stirling Albion was decided by the toss of a coin - which Dumbarton lost - the second such loss in successive seasons.
