Elmbridge is a local government district and borough in Surrey, England. Its council is based in Esher. The district has only one civil parish, which is Claygate. The borough shares a boundary with Greater London—the London Borough of Richmond upon Thames to the north and the Royal Borough of Kingston upon Thames to the east—and borders the Surrey boroughs of Runnymede, Spelthorne, Woking, Guildford and Mole Valley. Elmbridge is located almost entirely within the bounds of the M25 motorway.

Elmbridge is named after the Elmbridge hundred, which appears in Domesday Book of 1086 as Amelebrige. The district was formed on 1 April 1974 following the Local Government Act 1972.

The borough is governed by Elmbridge Borough Council. Prior to 1974, the borough was split between the Esher Urban District, whose council had existed since 1933, and the Walton and Weybridge Urban District. The councils arms were created upon the formation of the present day district, being formed out of symbols taken from the local towns and villages. A new Civic Centre was opened in 1991.
