Sàileag is Scottish mountain located on the northern side of Glen Shiel, 27 kilometres south east of Kyle of Lochalsh.

It is part of a mountain group called the North Glen Shiel Ridge which also includes two other Munros (Sgurr a' Bhealaich Dheirg and Aonach Meadhoin) and with a height of 956 metres (3136 feet) it is the lowest of all the six Munros on the northern side of Glen Shiel, making the mountain's translated name of “The Little Heel” quite appropriate.

The northern ridge is rocky and descends to the head of Gleann Lichd where it connects with the lower slopes of Beinn Fhada.

A traveller going down Glen Shiel in 1803 commented of the slope, "an inclined wall, of such inaccessible height that no living creature would venture to scale it".

The most common starting place for the ascent of Sàileag is the car park on the A87 road at grid reference NH008135 where there is a considerable gap in the trees which allows easy access to the mountainside.
