Scottish Highlands, also called Highlands, major physiographic and cultural division of Scotland, lying northwest of a line drawn from Dumbarton, near the head of the Firth of Clyde on the western coast, to Stonehaven, on the eastern coast.

The Scottish Highlands include the rugged and mountainous regions of Scotland north and west of the Highland Boundary Fault, although the exact boundaries are not clearly defined, particularly to the east. The Great Glen divides the Grampian Mountains to the southeast from the Northwest Highlands.
