Thwaite Priory was a monastery at Welton le Marsh in Lincolnshire, England. It was a house of Augustinian Canons Regular, dependent on Thornton Abbey, founded before 1440 and thought to have been dissolved before 1536.
Part of the remains were incorporated into an 18th-century cottage named Thwaite Hall. It is now a Grade II listed building.[1]
