Pontypridd Cynon Merthyr
constituency of the Senedd
Pontypridd Cynon Merthyr (Welsh for 'Pontypridd, Cynon, [and] Merthyr (Tydfil)'; ) is a six-member constituency of the Senedd (Welsh Parliament; Welsh: Senedd Cymru) used in the 2026 Senedd election. It covers areas in the south-east of Wales, particularly parts of Merthyr Tydfil and Rhondda Cynon Taf.
It was proposed following the 2026 review of Senedd constituencies, and was a pairing of the two UK Parliament constituencies of Merthyr Tydfil and Aberdare and Pontypridd. It has a Welsh-only name.
Boundaries
A Senedd constituency comprising the boundaries of the UK Parliament constituencies of Merthyr Tydfil and Aberdare and Pontypridd, has been proposed by the Democracy and Boundary Commission Cymru for the 2026 election to the Senedd (Welsh Parliament; Senedd Cymru). It was initially proposed using the English name Merthyr Tydfil, Aberdare and Pontypridd in September 2024, but was renamed to Merthyr Cynon Taf in December proposals with most constituencies using Welsh-only names. It was then given the Welsh-only name Pontypridd Cynon Merthyr and its boundaries were confirmed in the commission's final recommendations in March 2025. When announcing their candidates, Reform UK used "Merthyr Tydfil and Aberdare, Pontypridd" instead, using the English names for the pair of UK Parliament constituencies that form it.
It encompasses parts of the principal areas (county boroughs) of Merthyr Tydfil County Borough and Rhondda Cynon Taf in South Wales. The constituency was established in 2026, following the passing of the Senedd Cymru (Members and Elections) Act 2024.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Pontypridd Cynon Merthyr”, the useful work is to connect “constituency of the Senedd” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 14, 2026. The linked authority identifier is Q133539773. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2026, 2024 and 2025.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
