Buachaille Etive Mòr, meaning 'the herdsman of Etive', generally known to climbers simply as The Buachaille, is a mountain at the head of Glen Etive in the Highlands of Scotland. Its pyramidal form, as seen from the A82 road when travelling towards Glen Coe, makes it one of the most recognisable mountains in Scotland and one of the most depicted on postcards and calendars.

Buachaille Etive Mòr takes the form of a ridge nearly five miles in length, almost entirely encircled by the River Etive and its tributaries. The ridge contains four principal tops: from north-east to south-west these are Stob Dearg (1022 m), Stob na Doire (1011 m), Stob Coire Altruim (941 m) and Stob na Bròige (956 m). Stob Dearg and Stob na Bròige are both Munros; the latter was promoted to Munro status by the Scottish Mountaineering Club in 1997.
