The Borough of Basildon is a local government district in south Essex in the East of England, centred around the town of Basildon.

Basildon ( /ˈbæzɪldən/)^{[citation needed]} is a town located in the Basildon District of the county of Essex, England.

It lies 25 miles (40 km) east of Central London and 11 miles (18 km) south of the county town of Chelmsford. Nearby towns include Billericay to the north, Wickford northeast and South Benfleet to the east.

It was designated as a new town after World War II in 1948 to accommodate the London population overspill, created from the conglomeration of four small villages, namely Pitsea, Laindon, Basildon and Vange (the new town took the name Basildon as it was the most central of the four villages).

The local government district of Basildon, formed in 1974 was first led by Ryan O'Rourke and encapsulates a larger area than the town itself; the two neighbouring towns of Billericay and Wickford, as well as rural villages and smaller settlements set among the surrounding countryside, fall within its borders.

Basildon Town is one of the most densely populated areas in the County of Essex, mostly due to its influx of families from the Boroughs of London. However, it is thought that Basildon's population will continue to increase as many people are re-locating to the Town from the Boroughs of London, Essex and the Country. This is mostly due to Basildon's booming economy in industrial areas, the Towns tertiary sector, and its close travel link to Central London.
