1986–87 Dumbarton F.C. season

Season 1986–87 was the 103rd football season in which Dumbarton competed at a Scottish national level, entering the Scottish Football League for the 81st time, the Scottish Cup for the 92nd time and the Scottish League Cup for the 40th time.

Overview
Dumbarton began another First Division campaign with a new manager at the helm - Alex Totten - who had been released from his duties with Rangers following the arrival of Graeme Souness. Following another league reconstruction, the First Division clubs would play each other 4 times - a big ask particularly for the part-time clubs - but as things turned out it was to be a close thing for promotion with Dumbarton always up with the front runners. In the end, it was to be a 3rd-place finish - just 4 points behind champions Morton.

In the Scottish Cup, it would be another early exit for Dumbarton, this time to Brechin City after a draw, in the third round.

In the League Cup, Stirling Albion were dispatched in the second round before a fighting display against Celtic, saw Dumbarton's interest in the competition come to an end for another year.

Locally, Dumbarton failed to keep a grip on the Stirlingshire Cup, with Stirling Albion gaining some revenge for their League Cup exit, with a semi final win.
