Coigach (Scottish Gaelic: A' Chòigeach) today refers to the peninsula "beyond the big rock" north of Ullapool, in Wester Ross in the Northwest Highlands of Scotland. Until changes in civil registration districts in 1857 the Barony also included Isle Martin, the lands down to Corrie beyond Ullapool, the various farms of Strathkanaird, to the east the Forest of Achall and Rhiddorach.
