Afan Ogwr Rhondda ( Welsh for ' Afan , Ogmore , [and] Rhondda ') is a proposed six-member constituency of the Senedd (Welsh Parliament; Welsh : Senedd Cymru) to be used for the 2026 Senedd election.

It was proposed following the 2026 review of Senedd constituencies, and will be a pairing of the two UK Parliament constituencies of Aberafan Maesteg and Rhondda and Ogmore. It is to have a Welsh-only name.

Boundaries

A Senedd constituency comprising the boundaries of the UK Parliament constituencies of Aberafan Maesteg and Rhondda and Ogmore, 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 name Aberafan Maesteg, Rhondda and Ogmore in September 2024, ^[1] but was renamed to Afan Ogwr Rhondda in December proposals with most constituencies using Welsh-only names. ^[2] The Welsh-only name and boundaries were confirmed in the commission's final recommendations in March 2025. ^[3]

It encompasses parts of the principal areas (counties/county boroughs) of Bridgend County Borough, Neath Port Talbot and Rhondda Cynon Taf in South Wales. The constituency is to be established by 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. ^[1]
