Loch Broom is a sea loch located in northwestern Ross and Cromarty, in the former parish of Lochbroom, on the west coast of Scotland. The small town of Ullapool lies on the eastern shore of the loch.

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.
