Utto was an 8th-century Benedictine monk who served as the inaugural abbot of Metten Abbey in Bavaria. Born in Milan, he likely lived as a monk at Reichenau before being sent to help establish the Bavarian settlement. Tradition suggests he was the godson of Gamelbert, the landowner who founded the abbey around 766. Historical records from the late 8th century confirm his leadership role within the Benedictine order during this formative period of the monastery.
