The Exmoor Horn is a white faced, horned breed of sheep. It was developed in Exmoor, Devon, in the 19th century, but is a descendant of the horned sheep that roamed on the moors for centuries.

The Exmoor Horn sheep is classified as a Hill Breed and is found in upland areas of South West England, particularly Exmoor and Dartmour. Research by the Exmoor National Park has found that numbers have gradually declined for this breed. It is estimated that in 1947 over 27% of sheep in the Somerset part of Exmoor were pure bred Exmoor Horns. As the number of sheep in the region has increased, so the percentage of Exmoor Horn has dropped, and today breeding Exmoor Horn ewes represent only about 10% of the total sheep on Exmoor. The National Park reports that there are about 19,000 registered breeding ewes today, of which around 15,000 are on Exmoor. Small numbers are also found on neighbouring Dartmoor.

Exmoor Horn are a true dual-purpose sheep. It is a prolific breed, producing quality lambs as well as marketable fleece. A hardy and easily-maintained breed, the Exmoor Horn was and is an ideal sheep for the high moors of England.

Exmoor Horn have a high quality white fleece of medium length with excellent felting properties. It is used for hosiery, knitting yarns, tweeds and felts.
