An Stùc, meaning "The Peak" in Gaelic, is a conically shaped Scottish mountain in the Ben Lawers range to the north of Loch Tay.

It has been listed as a Munro since 1997, having previously been considered a subsidiary top of the Ben Lawers range.

[1] The normal routes of ascent are via the ridges from Ben Lawers or Meall Garbh, in combination with other summits in the range.

It may also be ascended directly from the Lawers Burn to the east via a gully above Lochan nan Cat.

[3] There is another An Stùc in Assynt, standing at 364 m (1,194 ft) about 26 kilometres (16 mi) northeast of Ullapool at the head of Glenoykel.
