Tolworth is a mostly residential area of outer South London in the Royal Borough of Kingston upon Thames, located 11.1 miles (17.9 km) south west of Charing Cross. Neighbouring places include: New Malden, Kingston, Surbiton, Berrylands, Chessington, Ewell and Worcester Park.

Tolworth, in the Domesday Book, was called Taleorde. Its Domesday assets were held partly by Picot from Richard de Tonebrige and partly by Radulf (Ralph) from the Bishop of Bayeux. It rendered: 2½ hides; also 4 hides with Long Ditton; 1 mill without dues, 8 ploughs, 10½ acres and ½ rod of meadow. It rendered £6.

An extensive low-lying development of 1940s single storey brick buildings, bounded by the A3 to the north and the rail line to the south, was occupied by the Ministry of Defence and the Directorate of Overseas Surveys but after remaining empty for some years it was demolished in 2008 and the site currently awaits redevelopment.

In the 1930s, '40s and '50s the clay extraction requirements of a brick factory north of the A3 off Red Lion Road (now Red Lion Industrial Park) produced a large water-filled pit (known locally as "The Bluey") which was used as a landfill site for bomb-damage and industrial material removed from bomb-sites resulting from the "Blitz". This land has been reclaimed and is now a recreation ground. The Civil Defence Corps used to have a training site with a full-size mock-up of a bomb-damaged housing estate.
