New Addington is an area in South London, England in the London Borough of Croydon. It is located near the Greater London border with Surrey. It is a large local authority estate surrounded by the Metropolitan Green Belt of open countryside, woodland and golf courses. The Prime Meridian crosses the eastern edge of New Addington.
The area's isolation from the rest of the Croydon borough has given it a strong sense of community and independence. The Croydon Advertiser publishes a separate New Addington edition. The presence of the library, youth clubs, leisure centre, shops, churches and street market enables locals to lead full lives in many ways. The Addington Community Association has provided an important hub for the community.
