Bowerchalke or Bower Chalke is a village and civil parish in Wiltshire, England, about 9 miles (14 km) southwest of Salisbury. It is in the south of Wiltshire, about 1 mile (1.6 km) from the county boundary with Dorset and 2 miles (3.2 km) from that with Hampshire. It is in the Cranborne Chase and West Wiltshire Downs Area of Outstanding Natural Beauty, which is part of the Southern England Chalk Formation. The River Chalke, a classic chalk stream, rises in the village and joins the River Ebble at Broad Chalke, flowing into the Hampshire Avon south of Salisbury. The Bowerchalke Downs, also known as Woodminton Down, Marleycombe Down and Knowle Down, were defined as a 318 acres (129 ha) Site of Special Scientific Interest in 1971.
The church of the Holy Trinity dates from the 13th century, and Nobel Prize winning novelist William Golding is buried in the churchyard.
