Selby and Ainsty was a constituency in North Yorkshire.
Further to the completion of the 2023 Periodic Review of Westminster constituencies, the seat was subject to boundary changes involving the loss of the Ainsty area. As a consequence, it reverted to the name of Selby, which was first contested at the 2024 general election.
