Cheam is a large suburban village in the London Borough of Sutton, England, and is an elongated area just inside the southern boundary of Greater London where it meets Surrey. It is divided into two main areas: North Cheam and Cheam Village. North Cheam includes more retail shops and supermarkets, whilst Cheam Village and the south of Cheam are more residential. The Village does, however, constitute a small retail and restaurant quarter in its own right (see below).
Cheam has a number of listed buildings, including Lumley Chapel and the 16th-century Whitehall Gallery, and is adjacent to two large adjoining parks, Nonsuch Park and Cheam Park. Nonsuch Park contains the listed Nonsuch Mansion. Parts of Cheam Park and Cheam Village are in a conservation area.
In common with neighbouring Sutton, Cheam is a film location, and a number of television programmes have been shot there over the years.
