The Daventry District was from 1974 to 2021 a local government district in western Northamptonshire, England. The district was named after its main town of Daventry where the council was based. The district was created on 1 April 1974, under the Local Government Act 1972, by a merger of the historic municipal borough of Daventry with the Daventry Rural District and most of the Brixworth Rural District. The town of Daventry became an unparished area with Charter Trustees and remained so until 2003 when a civil parish was created, roughly corresponding with the boundaries of the former borough, so allowing Daventry to have its own town council.
