St Benet's Abbey, also known as St Benet's at Holme or St Benet Hulme, was a medieval monastery of the Order of Saint Benedict situated at Cow Holm in Horning, Norfolk, England. It lay on the River Bure within the Broads. St Benet is a medieval English version of the name of St Benedict of Nursia, hailed as the founder of western monasticism. At the period of the Dissolution of the Monasteries the abbey's possessions were in effect seized by the crown and assigned to the diocese of Norwich. Though the monastery was supposed to continue as a community, within a few years at least the monks had dispersed. Today there remain only ruins.
