Sedgefield was a constituency in County Durham represented in the House of Commons of the UK Parliament from 1918 to 1974 and again from 1983 to 2024. Its final Member of Parliament (MP) was Paul Howell of the Conservative Party, who held the seat from 2019 until its abolition for the 2024 general election.

From 1983 to 2007, its MP was Tony Blair, who served as Prime Minister from 1997 to 2007.

Under the 2023 review of Westminster constituencies, the seat was abolished. Subject to major boundary changes, though retaining the town of Sedgefield, the constituency was reformed as Newton Aycliffe and Spennymoor to reflect the two largest communities in the revised seat.
