Calcutt is a hamlet about 3⁄4 mile (1.2 km) east of Cricklade in Wiltshire, England.
It lies near the River Thames and is divided by the A419 Swindon-Cricklade-Cirencester road.
The River Key passes close to the west of the hamlet and joins the Thames a short distance to the north.
The Domesday Book of 1086 records a small settlement of nine households at Colecote, held by Odo of Winchester.
Calcutt has two Grade II* listed buildings: Calcutt Court Farmhouse, south of the A419, from the 18th century; and Calcutt Farmhouse, north of the road, from the late 18th or early 19th.
