; ) is a six-member constituency of the Senedd (Welsh Parliament; ) used in the 2026 Senedd election. It covers most of the principal area of Swansea.
It was proposed following the 2026 review of Senedd constituencies, and is a pairing of the two UK Parliament constituencies of Gower and Swansea West. It has a Welsh-only name.
Boundaries The constituency covers most the principal area of Swansea, including Swansea city centre, the Gower Peninsula, Loughor and Pontarddulais. It does not include Clydach or the areas east of the River Tawe, such as St Thomas and Port Tennant.
A Senedd constituency comprising the boundaries of the UK Parliament constituencies of Gower and Swansea West, 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 Swansea West and Gower in September 2024, but was shortened to Swansea West Gower and its Welsh name being , in December proposals, despite most other constituencies using Welsh-only names. It was later given the Welsh-only name and its boundaries were confirmed in the commission's final recommendations in March 2025. When announcing their candidates, Reform UK used "Gower, Swansea West" 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.
