Mommolin of Fleury was a 7th-century Benedictine monk who served as the second abbot of Fleury Abbey for three decades. Leading the monastery from 632 until his death in 663, he is primarily known for organizing the transfer of the relics of Saint Benedict and Saint Scholastica from Monte Cassino to France. His leadership and the acquisition of these holy remains significantly increased the prestige and influence of the Fleury monastery, which later became known as Saint-Benoît-sur-Loire.
