Slioch is a mountain in the Scottish Highlands situated in Wester Ross, eight kilometres north of the village of Kinlochewe. Slioch reaches a height of 981 metres and towers above the south east end of Loch Maree to give one of the best known and most photographed sights (from the A832 road) in the Highlands.

The mountain is composed of Torridonian sandstone on a base of Lewisian Gneiss and has steep crags on three sides and allows easy access for the walker only from the south east where the large open corrie of Coire na Sleaghaich has two ridges on its flanks which the walker can use. The mountain's name comes from the Gaelic word 'sleagh' which means 'the spear' and this only becomes obvious when Slioch is viewed from Lochan Fada to the west. From there, the subsidiary top of Sgurr an Tuill Bhain (Peak of the White Hollow at 933 metres) dominates as a slender peak and gives the mountain its name.
