Monks Kirby Priory was a priory, at first Benedictine and later Carthusian, in Monks Kirby, Warwickshire, England. It was founded in 1077 at what was then known as Kirkbury, by the Breton, Geoffrey de Wirche (or Guerche), who had been granted lands in the area as a reward for his support of William of Normandy. He granted some of his land and tithes, together with the church of Kirkbury and two priests, to establish a cell or priory of Benedictine monks subject to the Abbey of St. Nicholas at Angers.
