St Dogmael’s Abbey is an abbey in Pembrokeshire, Wales. It was founded about 1115 for a prior and twelve monks of the Tironensian Order. The founders were Robert fitz Martin and his wife, Maud Peverel (sister of William Peverel the younger, d.1149). The buildings are now mostly ruins, though extensive walls and arches remain.
The abbey is close to Cardigan and Poppit Sands.
