List of parliamentary constituencies in Avon

Avon was abolished in 1996 both as a county council and a ceremonial county, but the name Avon continues to be used unofficially in subsequent boundary reviews as presented by the Boundary Commission for England to describe the area covered by the former county for the purpose of the rules which strongly deter cross-council constituencies (spanning more than one local authority within its area).

The Boundary Commission for England reviewed Avon in 2000 and devised a constituencies scheme in which no constituency spanned the four unitary authority boundaries within the abolished county. This entailed four seats to Bristol, three to South Gloucestershire and two each to Bath and North East Somerset and North Somerset and accordingly a net increase of one seat. Constituency names were aligned with the new local council names. These changes were implemented at the 2010 general election. Bath was restored as a borough constituency (to which a different election expenses quota and returning officer applies compared to county constituencies). Thus Avon has 6 borough constituencies and 5 county constituencies.

Following the 2023 Periodic Review of Westminster constituencies, Avon underwent further boundary changes, although the total number of seats was retained at 11.

Following the abandonment of the Sixth Periodic Review (the 2018 review), the Boundary Commission for England formally launched the 2023 Review on 5 January 2021. Initial proposals were published on 8 June 2021 and, following two periods of public consultation, revised proposals were published on 8 November 2022. The final proposals were published on 28 June 2023.

The commission proposed that "Avon" (covering the Bath and North East Somerset, Bristol, North Somerset, and South Gloucestershire council areas) be combined 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 will be established as cross-authority boundary seats. These changes came into effect for the 2024 general election.

The following seats are proposed:

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.

(The maps on this page do not show the nominal extensions of several constituencies over the waters of the Bristol Channel.)

Other former constituencies in the area were:
 * Bristol Central abolished 1974

 * Bristol North East abolished 1983
 * South Gloucestershire abolished 1983
