Agericus of Verdun was a 6th-century Catholic bishop who served as an influential advisor to the Austrasian kings, specifically Sigebert I and Childebert II. Born in 521 to a peasant family in Harville, he was baptized by King Thierry I, who acted as his godfather. After pursuing religious studies, he was ordained a priest and eventually succeeded his mentor as the tenth Bishop of Verdun. He is remembered for his commitment to education, his charitable efforts toward the poor, and his significant political presence at the royal court.
