Parliamentary constituencies in Hertfordshire

As of the 2024 general election, seven of Hertfordshire's MPs are from the Labour Party, three are Conservatives, and two are Liberal Democrats.

Eleven are designated as county constituencies (in which candidates can spend more per head than their borough counterparts).

[1] Conservative † Labour ‡ Liberal Democrat ¤ For the 2023 Periodic Review of Westminster constituencies, which redrew the constituency map ahead of the 2024 United Kingdom general election, the Boundary Commission for England opted to combine Hertfordshire with Bedfordshire as a sub-region of the East of England region, with the creation of the cross-county boundary constituency of Hitchin.

These changes had knock-on effects in the rest of the county, with most of the rest of the constituencies undergoing relatively minor boundary changes, the only exceptions being North East Hertfordshire and Stevenage, which remained effectively unchanged (save minor realignments with new ward boundaries).
