List of Parliamentary constituencies in Hertfordshire
The county of Hertfordshire in England is divided into eleven Parliamentary constituencies. Each of the eleven elects a Member of Parliament (MP) to represent it at the United Kingdom (UK) Parliament in Westminster. As of the 2019 general election, ten of Hertfordshire's eleven MPs are Conservatives. The county currently has two urban borough constituencies (BC) – Broxbourne and Watford – while the other nine are classed as more rural county constituencies (CC).
Limits of the seats were amended by the Fifth Periodic Review of Westminster constituencies carried out by the Boundary Commission for England for future elections which have included 2010, 2015, 2017 and 2019. Each constituency is made up of whole or partial local government wards, which elect councillors at English local elections. Nine are designated as county constituencies (in which candidates can spend more per head than their borough counterparts). Two are borough constituencies.

2010 boundary changes
The Boundary Commission for England decided not to change Hertfordshire's representation in Parliament for the 2010 election. It did however suggest slight boundary changes to reduce electoral disparity. The recommendations, which became law with the Parliamentary Constituencies (England) Order 2007, also ensured that local government wards in Hertfordshire would no longer be split between two Parliamentary constituencies.
|Name||Boundaries 1997-2010||Boundaries 2010-present|
|2||Hemel Hempstead CC|
|3||Hertford and Stortford CC|
|5||Hitchin and Harpenden CC|
|6||North East Hertfordshire CC|
|7||South West Hertfordshire CC|
|8||St Albans CC|
|11||Welwyn Hatfield CC|
Proposed boundary changes
See 2023 Periodic Review of Westminster constituencies for further details.
Following the abandonment of the Sixth Periodic Review (the 2018 review), the Boundary Commission for England formally launched the 2023 Review on 5 January 2021 and published their initial proposals on 8 June 2021.
The Commission has proposed that Hertfordshire be combined with Bedfordshire as a sub-region of the Eastern Region, with the creation of the cross-county boundary constituency of Hitchin. As a result of the changes, Hitchin and Harpenden, and South West Hertfordshire would be abolished, and new constituencies named Harpenden and Berkhamsted, and Three Rivers would be created.The following seats are proposed:
Containing electoral wards in Broxbourne
- Broxbourne (part)
Containing electoral wards in Dacorum
- Harpenden and Berkhamsted (part)
- Three Rivers (part)
Containing electoral wards in East Hertfordshire
Containing electoral wards in Hertsmere
Containing electoral wards in North Hertfordshire
Containing electoral wards in St Albans
- Harpenden and Berkhamsted (part)
- St Albans
Containing electoral wards in Stevenage
- Stevenage (part)
Containing electoral wards in Three Rivers
- Three Rivers (part)
Containing electoral wards in Watford
- Watford (part)
Containing electoral wards in Welwyn Hatfield
- Hertsmere (part)
- Welwyn Hatfield
Revised proposals will be published in late 2022 and the final report will be submitted in June 2023.
