Frithelstock Priory was founded in about 1220 at Frithelstock, Devon, England, by Sir Robert de Beauchamp for Augustinian Canons Regular, as an indulgence to ensure intercessions for the repose of his soul. Walter de Stapledon, Bishop of Exeter, is considered a co-founder, for increasing the priory's endowments.
The priory was dissolved in 1536 during the Dissolution of the Monasteries and only ruins remain.
