The ceremonial county of Derbyshire (which includes the unitary authority of Derby) is divided into 11 parliamentary constituencies: three borough constituencies and eight county constituencies. Since the 2024 general election, all eleven constituencies have been represented by members of the Labour Party.
See 2023 Periodic Review of Westminster constituencies for further details.
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 eleven constituencies in Derbyshire, with minor boundary changes to reflect changes to electoral wards within the county and to bring the electorates within the statutory range. These changes came into effect from the 2024 general election .
The following constituencies were proposed:
Containing electoral wards from Amber Valley
Containing electoral wards from Bolsover
Containing electoral wards from Chesterfield
Containing electoral wards from Derby
Containing electoral wards from Derbyshire Dales
Containing electoral wards from Erewash
Containing electoral wards from High Peak
Containing electoral wards from North East Derbyshire
Containing electoral wards from South Derbyshire
