The Mounth is the broad upland in northeast Scotland between the Highland Boundary and the River Dee, at the eastern end of the Grampians.

The Grampian Mountains is one of the three major mountain ranges in Scotland, that together occupy about half of Scotland. The other two ranges are the Northwest Highlands and the Southern Uplands. The Grampian range extends southwest to northeast between the Highland Boundary Fault and the Great Glen. The range includes many of the highest mountains in the British Isles, including Ben Nevis and Ben Macdui.
