Sampford Brett is a village and civil parish situated at the south-western edge of the Quantock Hills, Somerset, England, less than 1 mile (1.6 km) south of Williton, just off the A358 road to Taunton.

The parish council's role also includes initiating projects for the maintenance and repair of parish facilities, as well as consulting with the district council on the maintenance, repair, and improvement of highways, drainage, footpaths, public transport, and street cleaning.

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

It is also part of the Bridgwater and West Somerset county constituency represented in the House of Commons of the Parliament of the United Kingdom.
