The Royal Abbey of Our Lady of Fontevraud or Fontevrault was a monastery in the village of Fontevraud-l'Abbaye, near Chinon, in the former French duchy of Anjou. It was founded in 1101 by the itinerant preacher Robert of Arbrissel. The foundation flourished and became the center of a new monastic Order, the Order of Fontevraud. This order was composed of double monasteries, in which the community consisted of both men and women — in separate quarters of the abbey — all of whom were subject to the authority of the Abbess of Fontevraud. The Abbey of Fontevraud itself consisted of four separate communities, all managed by the same abbess.

Robert of Arbrissel was an itinerant preacher, and founder of Fontevraud Abbey. He was born at Arbrissel and died at Orsan Priory in the present department of Cher.
