Clapham Common is an 89 hectares (220 acres)  triangular area of grassland situated 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 (110 acres) of the common are within the London Borough of Wandsworth and 46 hectares (110 acres) within the London Borough of Lambeth. 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. The roads surrounding the Common fall within the SW4 post code.
Features of the Common 
The Common contains three ponds, two of which are historical features, and a more modern paddling pool known as Cock Pond.
Eagle Pond and Mount Pond are used for angling and contain a variety of species including carp to 20 lb, roach, tench and bream. Eagle Pond was extensively refurbished in 2002 when it was completely drained, landscaped and replanted to provide a better habitat for the fish it contained. Long Pond has a century-old tradition of use for model boating.
The common is surrounded by many fine houses, built from the 1790s onwards, which became fashionable dwellings for wealthy business people in what was then a village detached from metropolitan London. Some were members of the Clapham Sect of evangelical reformers, including Lord Teignmouth and Henry Thornton, the banker and abolitionist. As London expanded in the 19th century Clapham was absorbed into the capital, with most of the remaining palatial or agricultural estates replaced with terraced housing by the early 1900s.
There are two mounds on the Battersea Rise side of the common, the remnants of World War II storage bunkers built on the common.
Holy Trinity Church (1776) is close to the North Side of the common. An Anglican church, it hosts its fete on the common every summer.
A memorial tree to actor Jeremy Brett - who had lived locally for many years prior to his death in 1995 - was planted on 30 March 2007.
The bandstand 
In the centre of the Common is the Clapham bandstand constructed in 1890. It is the largest bandstand in London and a Grade II Listed Building. For many years it was also erroneously thought to be one of the bandstands first erected in 1861 in the Royal Horticultural Society's gardens in South Kensington, which would have made it the oldest surviving cast iron bandstand in Europe. However, recent research has shown that these bandstands went to Southwark Park and Peckham Rye, and it appears that the Clapham bandstand was fabricated to a very similar design almost thirty years later. 
The bandstand's maintenance had been neglected by Lambeth Council for thirty years, and by 2001 it was thought to be in danger of collapse and had to be shored up with scaffolding for five years. In 2005-2006, a full restoration of the bandstand and surrounding landscape took place, partly funded by an £895,000 lottery grant from the Heritage Lottery Fund matched by £300,000 from Lambeth Council and a further £100,000 from local fundraising efforts and the proceeds of the Ben and Jerry's Summer Sundae event held on the Common. The drainage bund around the bandstand was restored with granite setts during the summer of 2011 at a cost of £12,000  to resolve design faults in the earlier works.
In the news 
Former Welsh Secretary in the UK government Ron Davies had a "moment of madness" in 1998 in an incident that took place on the Common. He was robbed at knife point on the Common and met some strangers to whom he gave a lift; those same people took his car, wallet and phone. Davies resigned, repeatedly denying the incident had anything to do with drugs or sex. Newspapers have since reported that Mr Davies admits being bisexual and has "been successfully treated for a compulsion to seek out gay partners".
Some parts of the common are used by men seeking anonymous sex with other men in public places ("cruising").

- Since 1977 the Latin American football League has played organised football on the red car pitches located on the south side of the common
