Duncan Morton Colquhoun (24 July 1915 – 2005) was a Scottish footballer who played as a forward.
Colquhoun trialled at several Football League clubs during the mid-1930s, including Fulham, Sheffield Wednesday and Hartlepools United, but failed to make a league appearance. He was signed by Wigan Athletic from Queen of the South, and spent three seasons at the club before joining Bristol City in November 1937.[4]
Colquhoun returned to Wigan Athletic after the Second World War.[5]
