Welsh Mountain sheep (Welsh: Defaid (sing;"Dafad") Mynydd Cymreig, pronounced [ˈdevaɪd ˈmənɪð ˈkəmrɛɨɡ]) are small, hardy sheep from the higher parts of the Welsh mountains. The males have horns, and the females are polled (hornless); they have no wool on the face or legs, and they have long tails (normally left undocked).
There are a number of varieties, bred for sheep farming in Wales. These are mainly colour variations, but some are being developed as separate breeds.
White Welsh Mountain sheep, all-white. The most common variety in the Welsh Mountains; also kept elsewhere.
