Map - South Gloucestershire (South Gloucestershire)

South Gloucestershire is a unitary authority area in the ceremonial county of Gloucestershire, South West England. Towns in the area include Yate, Chipping Sodbury, Thornbury, Filton, Patchway and Bradley Stoke, the latter three forming part of the northern Bristol suburbs. The unitary authority also covers many outlying villages and hamlets. The southern part of its area falls within the Greater Bristol urban area surrounding the city of Bristol.

South Gloucestershire was created in 1996 to replace the Northavon district of the abolished county of Avon. It is separate from Gloucestershire County Council, but is part of the ceremonial county and shares Gloucestershire's Lord Lieutenant (the Sovereign's representative to the county). Because of its history as part of the county of Avon, South Gloucestershire works closely with the other unitary authorities that took over when that county was abolished, including shared services such as Avon Fire and Rescue Service and Avon and Somerset Police, together with co-operation in planning strategy for transport, roads and housing.

Prior to the implementation of the Local Government Act 1972 on 1 April 1974, the area that now forms South Gloucestershire formed part of the shire county of Gloucestershire, comprising the urban districts of Kingswood and Mangotsfield and the Rural Districts of Warmley, Sodbury and Thornbury. However, under the terms of that act, the area was removed from Gloucestershire, and became part of the county of Avon, forming the districts of Kingswood and Northavon.

In 1996, the county of Avon was abolished, and South Gloucestershire was created as a unitary authority area comprising the former districts of Kingswood and Northavon. The area borders the city and county of Bristol, the Bath and North East Somerset unitary authority area, and the shire counties of Gloucestershire and Wiltshire.

The geographic area currently known as South Gloucestershire should not be confused with Southern Gloucestershire. Nor should organisations or bodies in the past titled 'South Gloucestershire' (meaning Southern Gloucestershire) be confused with the area covered by the unitary authority.
