The Whitefaced Woodland is a sheep breed from the South Pennines in England, also known as the Penistone sheep after the Yorkshire town where sheep sales have been held since 1699. It is thought to be closely related to the Swaledale and the Lonk. Substantial commercial flocks of the Whitefaced Woodland are kept in its region of origin, but it is listed as a vulnerable breed by the Rare Breeds Survival Trust, since there are fewer than 900 registered breeding females in Great Britain.
