Great Bricett Priory was a medieval monastic house in Suffolk, England, now in use as a Church of England parish church. Ralph FitzBrian and Emma his wife, about the year 1110, founded a priory for Austin canons at Bricett, which was dedicated to the honour of St. Leonard. The foundation charter endowed the priory with the tithes of Bricett and of 'Losa' with its chapel, a moiety of the church of 'Stepla,' and the church of Stangate, Essex, in addition to various plots of land in the vicinity.
