Achiltibuie is a long linear village in Ross and Cromarty, Highland, on the Coigach coast of northwestern Scotland, overlooking Badentarbet Bay to the west. Loch Broom and the Summer Isles lie to the south. Located 10 miles (16 km) northwest of Ullapool as the crow flies. Achiltibuie is the central community of a series of townships and communities stretching from Culnacraig, through Badenscallie and Polglass, Polbain, and Reiff to Achnahaird.

Ross and Cromarty, also referred to as Ross-shire and Cromartyshire, is a variously defined area in the Highlands and Islands of Scotland. There is a registration county and a lieutenancy area in current use, the latter of which is 8,019 square kilometres in extent. Historically there has also been a constituency of the Parliament of the United Kingdom, a local government county, a district of the Highland local government region and a management area of the Highland Council. The local government county is now divided between two local government areas: the Highland area and Na h-Eileanan Siar. Ross and Cromarty border Sutherland to the north and Inverness-shire to the south.
