Odilo of Cluny (c. 962 – 1 January 1049) was the fifth Benedictine Abbot of Cluny, holding the post for around 54 years. During his tenure Cluny became the most important monastery in western Europe. Odilo actively worked to reform the monastic practices not only at Cluny, but at other Benedictine houses. He also promoted the Truce of God whereby military hostilities were temporarily suspended at certain times for ostensibly religious reasons.

As a child, he developed a great devotion to the Virgin Mary. While still quite young, he entered the seminary of St. Julien in Brioude, where he became a specialist in canon law. William of Dijon persuaded him to enter the monastery of Cluny. In 991, at the age of twenty-nine, he entered Cluny and before the end of his year of probation was made coadjutor to Abbot Mayeul, and shortly before the latter's death (994) was made abbot and received Holy orders.
