1985–86 Dumbarton F.C. season

Dumbarton returned to the First Division as favourites for the title, and in mid October the team was sitting atop the league.

However results took an inexplicable nosedive with 2 wins in 11 games, accounting for Davie Wilson's resignation at the beginning of February.

Locally, however, in the Stirlingshire Cup, there was something to smile about with the trophy returning to Boghead after a final win over Clydebank.

Finally, despite losing Premier Division status, Dumbarton were invited to participate in the annual televised indoor Tennent's Sixes tournament, as both Rangers and Celtic had declined to enter.

Dumbarton competed in the Scottish Reserve League (West), winning 10 and drawing 5 of 18 matches finishing runners up to Airdrie.
