Ceredigion Penfro (Welsh for 'Ceredigion [and] Pembroke'; 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 Ceredigion Preseli and Mid and South Pembrokeshire. Like all constituencies resulting from the 2026 review, it is to have a Welsh-only name.
