Gwynedd Maldwyn (Welsh for 'Gwynedd [and] Montgomeryshire'; ⓘ) is a six-member constituency of the Senedd (Welsh Parliament; Welsh: Senedd Cymru) used in the 2026 Senedd election. It is located in North and Mid Wales, and covers western and southern Gwynedd, southern Denbighshire, northern Powys, and the south-west of Wrexham County Borough.

It was proposed following the 2026 review of Senedd constituencies, and is a pairing of the two UK Parliament constituencies Dwyfor Meirionnydd and Montgomeryshire and Glyndŵr. It has a Welsh-only name.
Boundaries
The constituency includes Gwynedd with the exception of the area around Bangor and Bethesda in the north; the area around Corwen in southern Denbighshire; northern Powys, including Llanidloes and Newtown; and the south-west of Wrexham County Borough including Rhostyllen.
A Senedd constituency comprising the boundaries of the UK Parliament constituencies of Dwyfor Meirionnydd and Montgomeryshire and Glyndŵr, 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 Dwyfor Meirionnydd, Montgomeryshire and Glyndŵr in September 2024,[2] but was renamed to Gwynedd Maldwyn 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 "Dwyfor Meirionnydd, Montgomeryshire and Glyndŵr" instead, using the English names for the pair of UK Parliament constituencies that form it.[5]
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]
