Inglesham is a small village and civil parish in the Borough of Swindon, Wiltshire, England, notable for the Grade-I listed St John the Baptist Church.

Most of the population lives in the hamlet of Upper Inglesham, which is on the main road about 1.3 miles (2 km) south of the village.

[2] The Round House, Inglesham is often used by boaters as a landmark to denote the westernmost point most cabin cruisers and narrowboats can travel along the Thames, as beyond Inglesham the river becomes too clogged with vegetation and too shallow to effectively navigate.

The 13th-century parish church of St John the Baptist was restored in 1888–89[3] and is listed Grade I.

[12] Several other houses in the parish are listed Grade II, as are the late 18th-century Halfpenny Bridge that carries the A361 across the Thames into Lechlade,[13] and a Cotswold stone rubble barn at College Farm built in about 1800.
