Carlops (Scottish Gaelic: Leum na Caillich) is a small village in the Pentland Hills, within the Scottish Borders area of Scotland, close to the boundary with Midlothian.
The village was founded in 1784 and developed cotton weaving, coalmining and limestone mining.
The name derives from "Witches' Leap" (Scots: "Carlins Lowp") as near the south of the village there are two exposed rock faces about 20 metres in height facing each other with a similar distance between them. Folklore maintained that witches would leap from one face to the other, over the chasm, for entertainment of an evening.
