Sgùrr nan Ceathreamhnan (Scottish Gaelic for 'peak of the quarters')[2] is a mountain in the Northwest Highlands of Scotland.

With a height of 1,151 metres (3,776 ft) it is classed as a Munro and ranked as the third highest mountain north of the Great Glen (after Carn Eighe and Mam Sodhail).

The ascent of Sgùrr nan Ceathreamhnan is a major undertaking best done during the long hours of summer daylight.

The shortest approach is from the Alltbeithe youth hostel in upper Glen Affric at grid reference NH079202 3.5 kilometres south of the summit; however, it is a major undertaking just to get to the hostel, with long walks in from Loch Cluanie to the south or from the road end in Glen Affric.

The view from the summit is one of remote mountainous country, although with the help of binoculars it is possible to see Inverness and the Kessock Bridge, over 70 kilometres away to the east.
