The Soay sheep is a breed of domestic sheep from Scotland.
It has descended from a population of feral sheep on the 250 acre island of Soay in the St. Kilda Archipelago.
Name of these animals is derived from the island of Soay. The island of Soay is about 65 kilometers from the Western Isles of Scotland.
The breed is one of the Northern European short-tailed sheep breeds.
It has been called the only living example of the small, primitive sheep which inhabited the British Isles before the coming of the Norsemen and the Romans.
