The Devon Closewool is a breed of domestic sheep originating in the Exmoor region of southwest England. This breed is raised primarily for meat. It was developed in the late 19th century by crossing native Exmoor ewes with a Devon Longwool ram. A breed society was formed in 1923, and the first flocks registered dated back to 1894. It has since expanded its range into neighbouring regions.

The Devon Closewool is a white-faced sheep with a dense, medium-length fleece. Both rams and ewes are naturally polled. The Devon Closewool is a medium-size sheep, with average ewes weigh 55 kg (121 lbs) to 60 kg (132 lbs) and rams weigh 90 kg (198 lbs). It is a breed with a stout, symmetrical appearance that is hardy and suited to open grasslands and heaths in the upland territory.
