Chettle House is a Grade I listed country manor house with Queen Anne style architecture in Chettle, North Dorset, England, about 6 miles (10 km) northeast of the town of Blandford Forum. It was built in 1710 for George Chafin, to designs of the architect Thomas Archer. The builders were William and Francis Smith from Warwick. Pevsner called it "the plum among Dorset houses of the early 18th century, and even nationally outstanding as a specimen of English Baroque".
