Cunibert was a seventh-century Frankish prelate who served as the ninth bishop of Cologne from 623 until his death in 663. Born into the Ripuarian Frankish aristocracy along the Moselle, he received his education at the court of Chlothar II in Metz. Before ascending to the episcopacy, he held the position of archdeacon in Trier. During his leadership, he acted as a significant political figure, serving as a tutor to King Sigebert III and acting as a co-regent for the kingdom of Austrasia.
