Saint Ivo of Chartres (also Ives, Yves, or Yvo; Latin: Ivonis Carnutensis) (c. 1040 – 23 December 1115) was the Bishop of Chartres, France from 1090 until his death, and an important canonist during the Investiture Crisis.

Ivo is claimed to have studied at the Abbey of Bec in Normandy under Lanfranc of Canterbury, where he would have met St. Anselm of Canterbury, the great scholastic theologian. In 1067 or not much later, he became, at the desire of his bishop, prior of the canons of Saint-Quentin at Beauvais. As Bishop of Chartres and a canonist he contended strongly against simony and opposed King Philip I of France's repudiation of his wife Bertha of Holland in order to marry Bertrade of Anjou in 1092. Ivo was briefly imprisoned for this opposition.

Three extensive canonical works, namely Tripartita, Decretum, and Panormia, are attributed to him. He corresponded extensively. His liturgical feast is observed on 23 May. It is not known whether or when he was canonized.

Ivo of Chartres was born in Beauvais, France to a family in or near Chartres circa 1040. He is claimed to have studied first in Paris, then in Abbey of Bec in Normandy where, according to the often unreliable Robert of Torigni, he studied under Lanfranc along with St. Anselm of Canterbury.
