The Scottish Highlands (Scottish Gaelic: A' Ghàidhealtachd, Scots: Hielands) 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. The Highlands are popularly described as one of the most scenic regions of Europe.

The area is generally sparsely populated, with many mountain ranges dominating the region, and includes the highest mountain in the British Isles, Ben Nevis. Before the 19th century however the Highlands was home to a much larger population, but due to a combination of factors including the outlawing of the traditional Highland way of life following the Second Jacobite Rising, the infamous Highland Clearances, and mass migration to urban areas during the Industrial Revolution, the area is now one of the most sparsely populated in Europe. The average population density in the Highlands and Islands is lower than that of Sweden, Norway, Papua New Guinea and Argentina.

The Highland Council is the administrative body for much of the Scottish Highlands, with its administrative centre at Inverness. However the Highlands also includes parts of the council areas of Aberdeenshire, Angus, Argyll and Bute, Moray, Perth and Kinross, and Stirling. Although the Isle of Arran administratively belongs to North Ayrshire, its northern part is generally regarded as part of the Highlands.
