Garmoran is an area of western Scotland. It lies at the south-western edge of the present Highland Region. It includes Knoydart, Morar, Moidart, Ardnamurchan, and the Small Isles. The medieval lordship of Garmoran was ruled by the MacRuari's, descendants of Somerled, and later formed part of the Lordship of the Isles. Castle Tioram, at the entrance to Loch Moidart, was one of the residences of the lords of Garmoran.
