Butley Priory, sometimes called Butley Abbey, was a religious house of Canons regular (Augustinians, Black canons) in Butley, Suffolk, dedicated to The Blessed Virgin Mary. It was founded in 1171 by Ranulf de Glanville (c. 1112-1190), Chief Justiciar to King Henry II (1180-1189), and was the sister foundation to Ranulf's house of White canons (Premonstratensians) at Leiston Abbey, a few miles to the north, founded c. 1183. Butley Priory was suppressed in 1538.
