Morden is a district and town in south London, England, within the London Borough of Merton. It adjoins Merton Park and Wimbledon to the north, Mitcham to the east, Sutton to the south and Worcester Park to the west, and is around 8 miles (13 km) south-southwest of Charing Cross. Prior to the creation of Greater London in 1965, for local government purposes, Morden was in the administrative county of Surrey. It is in the historic county of Surrey.

At the 2011 Census, Morden had a population of 48,233, including the wards of Cannon Hill, Lower Morden, Merton Park, Ravensbury and St Helier. Morden Hall Park, a National Trust park on the banks of the River Wandle adjacent to the town center, is a key feature of the area.

Despite London's suburban expansion, a little of the earlier rural nature of Morden has survived; for instance several grand period buildings remain, especially within Morden's parks. The area retains a good provision of parks and green spaces, many of them created from former country estates. The 125 acre Morden Hall Park is of particular note and is run by the National Trust (see below). Its main entrance is only a quarter-of-a-mile from Morden Underground Station.

The largest building in the town center is Crown House, sixties-built and 14 storeys tall; designed in 1959 by A. Green ARIBA and built between 1960 and 1962. The concave frontage of the building lends it some distinction, as does the "chessboard" style juxtaposition of its light and dark facade features. It incorporated The Crown public house, on which part of the building covered. The building is home to Merton Civic Centre and a large adjoining library.

At around the same time, Morden Underground Station, originally a single storey building, with shops, had three-storey office accommodation incorporated above it. A further office building with a large supermarket (now a Sainsbury's) at ground-floor level was built in the 1980s at the other end of the town center. The cinema and adjoining garage were demolished and replaced by shops some years ago.
