The Priory of St Mary Magdalene in Barnstaple was a priory in Devon, England. It was founded in about 1107 by Juhel de Totnes, feudal baron of Barnstaple, who had earlier founded Totnes Priory in about 1087 at the caput of his former feudal barony of Totnes, from which he had been expelled. Barnstaple Priory was of the Cluniac order. It was dedicated to St Mary Magdalene. It was situated on land outside the town walls stretching from the North Gate to the East Gate with the River Yeo forming its northern boundary. Nearby to the north across the River Yeo was the Benedictine Pilton Priory of St Mary the Virgin, a cell of Malmesbury Abbey, founded slightly later, between 1107 and 1199.
