Dumbarton Harp is a former Scottish League football club, which dropped out of the League in 1925.  They were formed in 1894 by Irish Catholic immigrants to the area in a similar way to the formation of Celtic in Glasgow and Hibernian in Edinburgh. Dumbarton Harp played the majority of their existence in local football leagues, such as the Glasgow and District Junior League, which they joined in their inaugural season, or the Inter County Football League in season 1916–17. In 1910 they were champions of the Scottish Football Union which they left in 1912 to participate in the Scottish Reserve Football League. They did play for a short spell in the Scottish Football League when it expanded to a three division set up in the 1920s. They finished tenth (out of 16 clubs) in the inaugural Division Three in the 1923–24 season, but withdrew midway through the 1924–25 season when it became clear they could not meet their financial commitments, and were disbanded.
