South Bucks is one of four local government districts in the non-metropolitan county of Buckinghamshire, in South East England.

The district was formed on 1 April 1974 by the Local Government Act 1972, by the amalgamation of the area of Beaconsfield Urban District with part of Eton Rural District. The district was originally named Beaconsfield: it was renamed to its present title on 1 April 1980, following the passing of a resolution by the district council. It is formally called 'South Bucks' rather than 'South Buckinghamshire'.
