Stevenage is a constituency[n 1] in Hertfordshire represented in the House of Commons of the UK Parliament since 2024 by Kevin Bonavia, a member of the Labour Party.

The main town is known for its fast rail links to London and proximity to Luton Airport which accompanies a few headquarters of global businesses based in the seat.

A Southern England new town seat with volatile voting patterns, like its main predecessor, it was a bellwether of the national result; it was Conservative held between 1983 and 1997 until Labour easily gained it, but their winning margin in 2005 was small and the Conservatives gained the seat at the 2010 election.

The 2023 periodic review of Westminster constituencies, which was based on the ward structures in place on 1 December 2020, left the boundaries virtually unchanged[6].

However, following local government boundary reviews in East Hertfordshire[7] and North Hertfordshire[8] which came into effect in May 2023 and May 2024 respectively, the constituency now comprises the following from the 2024 general election: The constituency covers the Borough of Stevenage, as well as the villages of Codicote and Knebworth to the south and Aston and Datchworth to the east.
