For the 2023 review of Westminster constituencies, which redrew the constituency map ahead of the 2024 United Kingdom general election, the Boundary Commission for England maintained seven constituencies in Northamptonshire, as detailed below, with boundary changes to reflect changes to ward boundaries following the reorganisation of local government authorities within the county and to bring the electorates within the statutory range. Corby was renamed Corby and East Northamptonshire, and Wellingborough renamed Wellingborough and Rushden. These changes came into effect from the 2024 general election.
