Clachnaben (archaically "Cloch-na'bain"; Scottish Gaelic: "Clach na Beinne") is a 589-metre hill in Glen Dye, Aberdeenshire, Scotland.

[1] It is a distinctive hill visible from many points on Lower Deeside and is topped with a large granite tor.

[2] Clachnaben is the war cry of Clan Strachan.

A popular walk starts at the car park on the Cairn O' Mounth (Banchory–Fettercairn) road, 10 kilometres south of Banchory.

[3] A new improved path takes an easier and less direct route from Millar's Bog to the summit.
