Pen-y-bont Bro Morgannwg (Welsh for 'Bridgend [and] Vale of Glamorgan'; listenⓘ) 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 Bridgend and the Vale of Glamorgan.

It was proposed following the 2026 review of Senedd constituencies, and is a pairing of the two UK Parliament constituencies of Bridgend and Vale of Glamorgan. It has a Welsh-only name.

Boundaries

A Senedd constituency comprising the boundaries of the UK Parliament constituencies of Bridgend and Vale of Glamorgan, 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 Vale of Glamorgan and Bridgend in September 2024,[2] but was renamed to Pen-y-bont Bro Morgannwg in December proposals with most constituencies using Welsh-only names.[3] The Welsh-only name and boundaries were confirmed in the commission's final recommendations in March 2025.[4] When announcing their candidates, Reform UK used "Bridgend, Vale of Glamorgan" instead, using the English names for the pair of UK Parliament constituencies that form it.[5]

It encompasses parts of the principal areas (county boroughs) of Bridgend County Borough and the Vale of Glamorgan in South Wales. The constituency was established in 2026, following the passing of the Senedd Cymru (Members and Elections) Act 2024. The act legislates electoral reform of the Senedd to create 16 larger "super constituencies", pairing the 32 UK Parliament constituencies in Wales, and using a new fully proportional voting system, with each constituency electing six Members of the Senedd (MSs) rather than one previously.[2]
