Sutherland (Scottish Gaelic: Cataibh) is a historic county, registration county and lieutenancy area in the Highlands of Scotland. The name dates from the Viking era when the area was ruled by the Jarl of Orkney; although Sutherland includes some of the northernmost land on the island of Great Britain, it was called Suðrland ("southern land") from the standpoint of Orkney and Caithness.
From the 13th century, Sutherland was a provincial lordship, being an earldom controlled by the Earl of Sutherland. The earldom just covered the southeastern part of the later county. A shire called Sutherland was created in 1633, covering the earldom of Sutherland and the neighbouring provinces of Assynt to the west and Strathnaver to the north. Shires gradually eclipsed the old provinces in administrative importance, and also become known as counties.
