The London Plan is the statutory spatial development strategy for the Greater London area in the United Kingdom that is written by the Mayor of London and published by the Greater London Authority. It is updated from time to time.

Greater London is the administrative area of London, England, which is coterminous with the London region. It contains 33 local government districts: the 32 London boroughs, which form a ceremonial county also called Greater London, and the City of London. The Greater London Authority is responsible for strategic local government across the region, and regular local government is the responsibility of the borough councils and the City of London Corporation. Greater London is bordered by the ceremonial counties of Hertfordshire to the north, Essex to the north-east, Kent to the south-east, Surrey to the south, and Berkshire and Buckinghamshire to the west.
