Ballybeg Priory, also known as Ballybeg Abbey, the Abbey of St Thomas, and St Thomas's Priory, is a 13th-century priory of the Augustinian order near the town of Buttevant, County Cork, Ireland. It is home to one of the best preserved and most substantial dovecots in Ireland. The priory was founded in 1229 and dissolved in 1541, the land and buildings passing into private hands. Those parts of the buildings that have escaped from the stone being removed for use in other buildings are mostly late medieval.
