South Cambridgeshire is a constituency[n 1] represented in the House of Commons of the UK Parliament since the 2024 general election by Pippa Heylings of the Liberal Democrats.

The previous MP Anthony Browne opted to fight the newly formed St Neots and Mid Cambridgeshire seat which contains part of his old constituency.

Before this, much of the region had been part of the now abolished South West Cambridgeshire constituency represented by Sir Anthony Grant from 1983 to 1997,[3] while the wards of Bar Hill, Coton, Elsworth, Girton, Longstanton and Swavesey were transferred from South East Cambridgeshire.

Following the 2007 review of parliamentary representation in Cambridgeshire, the Boundary Commission made minor alterations to the existing constituencies to deal with population changes.

To partly compensate, it gained the Cherry Hinton ward in the City of Cambridge and southern parts of the abolished constituency of South East Cambridgeshire, including the villages of Fulbourn and Linton.
