Hugh de Vivonne (died 1249) was a French knight from Vivonne in the County of Poitou. He was loyal to the Plantagenet family and supported their right to vast lands in France. From 1215 onward he made his home in England, where he was constable of Bristol Castle (1216–21, 1236–41) and later High Sheriff of Somerset and Dorset (1241–49). He married an English lady and became lord of Chewton and Curry Mallet. He received further English estates in compensation for the loss of his lands in France. Yet, as a foreign soldier in the king's pay, he has been described as merely a "Poitevin mercenary captain".
