Cynon Valley (Welsh: Cwm Cynon) was a constituency[n 1] in Wales, of the House of Commons of the UK Parliament from 1983 to 2024. Its last MP from 2019 to 2024 was Beth Winter of the Labour Party.[n 2]

The Cynon Valley Senedd constituency was created with the same boundaries in 1999 (as an Assembly constituency).

The constituency was abolished as part of the 2023 periodic review of Westminster constituencies and under the June 2023 final recommendations of the Boundary Commission for Wales. Its wards were split between Merthyr Tydfil and Aberdare, and Pontypridd.[3]
