Hammoon is a small village and civil parish in the English county of Dorset, sited on a river terrace[1] of alluvial silt by the River Stour,[2] about two miles (three kilometres) east of the small town of Sturminster Newton.

Its name is derived from the Old English ham, meaning dwelling, and the surname of the Norman lord of the manor ('de Moion' or 'Mohun').

[5] In 1086 in the Domesday Book Hammoon was recorded as Hame;[6] it had 15 households, 4 ploughlands and 50 acres (20 hectares) of meadow.

Near St. Paul's is the thatched and mullioned manor house, which dates from the 16th century and which Sir Frederick Treves described in 1906 as "the most picturesque of its kind".

It is an early example of the use of shuttered concrete as a building material, though the exterior was finished to give an appearance of stone.
