# Parliamentary constituencies in South Yorkshire

The ceremonial county of South Yorkshire is divided into 14 parliamentary constituencies – 5 borough constituencies and 9 county constituencies, one of which is partly in the District of North Lincolnshire.
Sheffield Hallam was the only non-Labour South Yorkshire seat for many years, and was held by Nick Clegg for 12 years, until Labour gained the seat in 2017. For a 22-year period spanning 1997–2019, the Conservatives had no seats in South Yorkshire, until the 2019 election, when they gained three. In the 1980s, the region's socialist activity (particularly in local government) led to it being referred to as the "People's Republic of South Yorkshire", it being dominated by Labour, a party with a strong socialist tradition. However, it was not until 2017 that every seat in South Yorkshire was won by Labour, a feat which was not repeated at the subsequent 2019 election. At the 2024 general election Labour regained all South Yorkshire constituencies.

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 South Yorkshire with the four unitary authorities which make up the former county of Humberside as a sub-region of the Yorkshire and the Humber Region, resulting in the creation of a new cross-county boundary constituency named Doncaster East and the Isle of Axholme, largely replacing Don Valley. Barnsley Central and Barnsley East were realigned to form Barnsley North and Barnsley South. Changes to Wentworth and Dearne resulted in it being renamed Rawmarsh and Conisbrough.
The following constituencies were proposed:
Containing electoral wards from Barnsley
* Barnsley North
* Barnsley South
* Penistone and Stocksbridge (part)
Containing electoral wards from Doncaster
* Doncaster East and the Isle of Axholme (part also in North Lincolnshire)
* Doncaster North
* Doncaster Central
* Rawmarsh and Conisbrough (part)
Containing electoral wards from Rotherham
* Rawmarsh and Conisbrough (part)
* Rother Valley
* Rotherham
Containing electoral wards from Sheffield
* Penistone and Stocksbridge (part)
* Sheffield Brightside and Hillsborough
* Sheffield Central
* Sheffield Hallam
* Sheffield Heeley
* Sheffield South East

### 2010

Under the Fifth Periodic Review of Westminster constituencies, the Boundary Commission for England decided to reduce the number of seats in South Yorkshire from 15 to 14, leading to significant changes. Barnsley East and Mexborough, Barnsley West and Penistone, Sheffield, Brightside, and Sheffield, Hillsborough were abolished and replaced by Barnsley East, Penistone and Stocksbridge, and Sheffield, Brightside and Hillsborough. Sheffield, Attercliffe was renamed Sheffield South East, and Wentworth was renamed Wentworth and Dearne.
