The approximate boundaries of the Merton Park area can be considered to be Kingston Road (A238) to the north, Dorset Road (B285) and Morden Road (A24) to the east, Martin Way to the south and Cannon Hill Lane to the west. Additionally, the area north of Kingston Road between Merton Hall Road, Avebury Road and Kingswood Road is often included. This definition of the area does not correspond directly with the Local Government ward of the same name which for administrative convenience includes areas as far south as Morden South railway station.
