; ) is a six-member constituency of the Senedd (Welsh Parliament; ) used in the 2026 Senedd election. It covers eastern Flintshire and the north and east of Wrexham County Borough, both in North Wales.
It was proposed following the 2026 review of Senedd constituencies, and is a pairing of the two UK Parliament constituencies of Alyn and Deeside and Wrexham. It has a Welsh-only name.
Boundaries The constituency covers eastern Flintshire, including Flint and Connah's Quay. It also includes the north and east of Wrexham County Borough, including Wrexham itself.
A Senedd constituency comprising the boundaries of the UK Parliament constituencies of Alyn and Deeside and Wrexham, has been proposed by the Democracy and Boundary Commission Cymru for the 2026 election to the Senedd (Welsh Parliament; ). It was initially proposed using the English name Alyn, Deeside and Wrexham in September 2024, but was renamed to in December proposals with most constituencies using Welsh-only names. The Welsh-only name and boundaries were confirmed in the commission's final recommendations in March 2025. When announcing their candidates, Reform UK used "Alyn and Deeside, Wrexham" instead, using the English names for the pair of UK Parliament constituencies that form it.
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.
