Banstead is a town in the borough of Reigate and Banstead in Surrey, England. It is 3 miles (5 km) south of Sutton, 5 miles (8 km) south-west of Croydon, 8 miles (13 km) south-east of Kingston-upon-Thames, and 13 miles (21 km) south of Central London.

On the North Downs, it is on three of the four main compass points separated from other settlements by open area buffers with Metropolitan Green Belt status. Banstead Downs, although a fragment of its larger historic area and spread between newer developments, is a Site of Special Scientific Interest (SSSI).

The civil parish of Banstead became part of the Epsom Rural Sanitary District on the district’s creation in 1872, and continued as part of its successor, the Epsom Rural District, from 1894 to 1933. In that year the Banstead Urban District was created incorporating also the parishes of Chipstead, Kingswood, Walton on the Hill, and Woodmansterne. The civil parish was abolished, like other parishes in former urban districts, when (under the Local Government Act 1972) the Banstead Urban District was subsumed into the new Reigate and Banstead Borough in 1974. Both parish and urban district included many outlying parts as well as the main settlement. One of the Banstead wards is “Banstead Village”. The contiguous ward of Nork, which contains Banstead station, shares in many amenities of Banstead and is included in county-level population analyses of Banstead but not the central-government-drawn Banstead Built-up Area. The latter takes in Burgh Heath and held 15,469 residents as at the 2011 census.
