Brycheiniog Tawe Nedd (Welsh for 'Brycheiniog, Tawe, [and] Neath'; listen) 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 Brecon, Radnor and Cwm Tawe and Neath and Swansea East. It is to have a Welsh-only name.
