was a former Scottish League football club from the small town of Clackmannan in the Central Lowlands. Based at Chapelhill Park, Clackmannan joined the Second Division of the Scottish League for the 1921–22 season when the Central League clubs formed most of this division. They finished bottom, and withdrew for a year to the Eastern League. Clackmannan gained admission to the new Third Division which was created in 1923. They played for three seasons in the Third Division without distinction. In their last season of Scottish League football (1925–26) they would have finished bottom had Galston not withdrawn halfway through the season. Indeed, the whole division folded at the end of 1925–26, having proved unsustainable due to financial difficulties.
