Newbo Abbey was a Premonstratensian house of canons regular in Lincolnshire, England, dedicated to the Assumption of Mary. In the Middle Ages, Lincolnshire was one of the most densely populated parts of England. Within the historical county there were no less than nine Premonstratensian houses. Other than Newbo Abbey, these were: Barlings Abbey, Cammeringham Priory, Hagnaby Abbey, Newsham Abbey, Orford Priory (women), Stixwould Priory, Tupholme Abbey and West Ravendale Priory.
