The county of Gloucestershire
is divided into 6 parliamentary constituencies: 2 borough constituencies
and 4 county constituencies.

Constituencies

2010 boundary changes 
Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to retain Gloucestershire's constituencies for the 2010 election, making minor changes to realign constituency boundaries with the boundaries of current local government wards, and to reduce the electoral disparity between constituencies. Although the changes were minor, the Cotswold constituency was renamed The Cotswolds.

Proposed boundary changes
See 2023 Periodic Review of Westminster constituencies for further details.

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 had proposed that Gloucestershire be combined with Wiltshire as a sub-region of the South West Region, with the creation of the cross-county boundary constituency of South Cotswolds, resulting in a major reconfiguration of existing constituency of The Cotswolds, which would be renamed North Cotswolds. 

The following seats are proposed:
