Downhead is a village and civil parish just south of Leigh-on-Mendip and 5 miles (8 km) north east of Shepton Mallet, in the Mendip district of Somerset, England.

South west of the village is Dinies Camp, a univallate Iron Age hill fort enclosure.

Conservation matters (including trees and listed buildings) and environmental issues are also of interest to the parish council.

[6] It is also part of the Frome and East Somerset county constituency represented in the House of Commons of the Parliament of the United Kingdom.

Most of the underlying rocks are calcareous Carboniferous Limestone and shales, but Devonian Portishead Beds outcrop along the northern valley.
