Snelshall Priory was a Benedictine priory in Milton Keynes, the United Kingdom, built around 1200. The priory was started after Sybil d'Aungerville granted land at Tattenhoe to Lavendon Abbey, who most likely started a cell at Snelshall. Snelshall Priory paid 1 mark a year to Lavendon until 1232, at which point the Bishop of Lincoln decided that Snelshall owned its own lands and chapel.
