North West Cambridgeshire is a county constituency represented in the House of Commons of the Parliament of the United Kingdom since 2024 by Sam Carling of the Labour Party.

This seat includes a substantial part of the cathedral city of Peterborough, specifically the suburban areas to the south of the river Nene and west of the Soke Parkway, as well as several rural wards from the historic county of Huntingdonshire.

The seat was won upon its creation in 1997 by Sir Brian Mawhinney, former Conservative MP for Peterborough (which was gained at the same election by the Labour Party).

The seat changed hands to Labour's Sam Carling in the 2024 United Kingdom general election.

The constituency was formed primarily from northern, rural parts of the Huntingdon constituency, including Ramsey, together with parts of Peterborough, comprising residential areas to the south of the River Nene (wards of Fletton, Orton Longueville, Orton Waterville and Stanground).Following their review of parliamentary representation in Cambridgeshire in 2005, the Boundary Commission for England made minor alterations to the existing constituencies to deal with population changes, including a small further gain from Huntingdon.
