Neston Park is an English country house and estate, 2 miles (3 km) south of Corsham, Wiltshire, in the village of Neston. The name of the village comes from the name of the house.
The house was built just after 1790. The estate extends from north of Neston village, southwards beyond Atworth, to South Wraxall, and also includes the certified organic home farm with a herd of Jersey cattle and unusual Aberdeen Angus and Jersey cross-bred cattle.
In the late 1990s, the estate obtained a Countryside Stewardship Scheme agreement from the government, supporting a programme of hedge, wall and wild flower field margin restoration. The estate's farm shop and coffee shop were established in Atworth in 2006.
Neston Park is not open to the public. The route of the ancient Roman road from London to Bath crosses the home farm from east to west, about 200 metres (700 feet) south of the house. The local portion of the road is sometimes known as the Wansdyke.
