Whitland Abbey (Welsh: Abaty Hendy-gwyn ar Daf or simply Y Tŷ Gwyn ar Daf; Latin, Albalanda) was a country house and Cistercian abbey in the parish of Llangan, in what was the hundred of Narbeth, Carmarthenshire, Wales. The town which grew up nearby is now named Whitland after it. It was widely known as Ty Gwyn ar Daf, meaning White House on the Taf, in reference to the country house originally built here before it became a monastic settlement which was known under that name.
