Coigach () is a peninsula north of Ullapool, in Wester Ross in the Northwest Highlands of Scotland. The area consists of a traditional crofting and fishing community of a couple of hundred houses located between mountain and shore on a peninsula looking over the Summer Isles and the sea. The main settlement is Achiltibuie. Like its northerly neighbour, Assynt in Sutherland, Coigach has mountains which rise sharply from quiet, lochan-studded moorland, and a highly indented rocky coast with many islands, bays and headlands. The highest summit is Ben Mor Coigach at 743 metres; the distinctive profile of Stac Pollaidh is the other main peak within Coigach. The scenic qualities of Coigach, along with neighbouring Assynt, have led to the area being designated as the Assynt-Coigach National Scenic Area, one of 40 such areas in Scotland.
