Kirn is a village on the Cowal Peninsula, in Argyll and Bute in the Scottish Highlands on the west shore of the Firth of Clyde on the Cowal peninsula. It now forms part of the continuous habitation between Dunoon and Hunters Quay, where the Holy Loch joins the Firth of Clyde. It originally had its own pier, with buildings designed by Harry Edward Clifford in 1895, and was a regular stop for the Clyde steamer services, bringing holidaymakers to the town, mostly from the Glasgow area.
