Kingswood was, from 1974 to 1996, a non-metropolitan district of the County of Avon, England.
It was formed on 1 April 1974, under the Local Government Act 1972, by the merger of the Kingswood and Mangotsfield urban districts with Warmley Rural District from the administrative county of Gloucestershire. In 1987 the district was granted borough status.
Following a review by the Local Government Commission for England, both the County of Avon and Borough of Kingswood were abolished on 1 April 1996. Kingswood was merged with the neighbouring Northavon District to form the unitary authority of South Gloucestershire.
