# Parliamentary constituencies in Avon

Avon was abolished in 1996 both as a county council and a ceremonial county, being succeeded by the unitary authorities of Bath and North East Somerset, Bristol, North Somerset, and South Gloucestershire. The constituency boundaries used up to the 2005 United Kingdom general election were drawn up when the county still existed. For the review which came into effect for the 2010 general election, the four authorities were considered separately, entailing four seats for Bristol, three for South Gloucestershire and two each for Bath and North East Somerset and North Somerset.
For the 2023 Periodic Review of Westminster constituencies, coming into effect for the 2024 United Kingdom general election, the Boundary Commission for England considered the area comprising the former county of Avon, together with Devon (including Plymouth and Torbay) and Somerset as a sub-region of the South West Region.
The area is divided into 13 parliamentary constituencies – 6 borough constituencies and 7 county constituencies, including two which cross local authority boundaries with Somerset.

For the 2023 Periodic Review of Westminster constituencies, which redrew the constituency map ahead of the 2024 United Kingdom general election, the Boundary Commission for England opted to combine "Avon" (covering the Bath and North East Somerset, Bristol, North Somerset, and South Gloucestershire council areas) with Devon and Somerset as a sub-region of the South West Region, resulting in significant change to the existing pattern of constituencies. In Avon, Bristol West, Kingswood and North East Somerset were abolished, being replaced by Bristol Central, Bristol North East, and North East Somerset and Hanham. In addition, Frome and East Somerset, and Wells and Mendip Hills were established as cross-authority boundary seats.
The following seats were proposed:
Containing electoral wards from Bath and North East Somerset
* Bath
* Frome and East Somerset (part also in the Somerset District of Mendip)
* North East Somerset and Hanham (part)
Containing electoral wards in Bristol
* Bristol Central
* Bristol East
* Bristol North East (part)
* Bristol North West
* Bristol South
Containing electoral wards in North Somerset
* North Somerset
* Wells and Mendip Hills (parts also in the Somerset Districts of Mendip and Sedgemoor)
* Weston-super-Mare
Containing electoral wards in South Gloucestershire
* Filton and Bradley Stoke
* North East Somerset and Hanham (part)
* North East Bristol (part)
* Thornbury and Yate

### 2010

Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to increase the number of seats which covered "Avon" from 10 to 11, with the creation of Filton and Bradley Stoke. This resulted in major changes to Kingswood and three of the four Bristol constituencies. A further three constituencies were renamed.
| Former name | Boundaries 1997–2010 | Former name | Boundaries 2010–2024 |
| Bath CC Bristol East BC Bristol North West BC Bristol South BC Bristol West BC Kingswood BC Northavon CC Wansdyke CC Weston-super-Mare CC Woodspring CC | Parliamentary constituencies in Avon | Bath BC Bristol East BC Bristol North West BC Bristol South BC Bristol West BC Filton and Bradley Stoke CC Kingswood BC North East Somerset CC North Somerset CC Thornbury and Yate CC Weston-super-Mare CC | Proposed Revised constituencies in Avon |
