Slevesholm Priory was a Cluniac priory in the civil parish of Methwold, Norfolk, England, that was dedicated to St. Mary and St. Giles. A cell of the Castle Acre Priory, Slevesholm Priory was either granted by William de Warenne, 5th Earl of Surrey between 1222-6 or established during the reign of king Stephen (1135–1154), and dissolved in 1537 during the dissolution of the monasteries. There are no extant remains of the priory; Historic England undertook field research in 1976 and remarked: "There are no physical remains of this [priory] at the formerly published site which is now under plough; farm workers questioned had no knowledge of early finds or foundations. [There is] impression of early quarrying [while] no recognisable pattern is evident and there is no surface trace of building material."
