Numbered map of the parliamentary constituencies of Dorset created by the 2023 boundary review and first used at the 2024 UK general election.

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 retain the eight current constituencies in Dorset, with minor boundary changes to reflect changes to ward boundaries following the reorganisation of local government authorities within the county.

The boundary commission recommended the following seats within Dorset:

Containing electoral wards from Bournemouth, Christchurch and Poole

Containing electoral wards from Dorset (unitary authority)
