Clapham Common is an 89 hectare (220 acre) triangular area of grassland situated between Clapham, Battersea and Balham in south London, England. It was historically common land for the parishes of Battersea and Clapham, but was converted to parkland under the terms of the Metropolitan Commons Act 1878.
43 hectares (108 acres) of the common (the area historically known as Battersea Common) are within the London Borough of Wandsworth. Although the Common is wholly managed and maintained by the London Borough of Lambeth, the policing of the open space is divided between the Wandsworth and Lambeth borough "commands" of the Metropolitan Police, which follow the local government boundaries.
Clapham Common is also the name of an electoral ward in the London Borough of Lambeth covering the area of housing to the southeast of Clapham Common Southside better known as "Abbeville Village" - see Clapham Town ward.
