Leudinus of Toul, also known as Bodo, was a seventh-century Benedictine monk who served as the Bishop of Toul. Born around 625 to an Austrasian noble family, he was the brother of Sadalberga, the founder of a monastery in Laon. Throughout his religious life, he established several important monastic sites, including the Abbey of Étival in 663 and the Abbey of Othonville. He is remembered as a significant figure in the early medieval church and is recognized as a saint.
