Barnes was a local government district in north west Surrey from 1894 to 1965. It was formed as an urban district in 1894 and became a municipal borough in 1932. It contained the settlements of Barnes, Mortlake and East Sheen. It was part of the London postal district and Metropolitan Police District. The district was bounded by the County of London to the east, the River Thames and Middlesex to the north, and the Municipal Borough of Richmond to the west and south. In 1965 it was abolished and its former area became part of the London Borough of Richmond upon Thames.
