Leudwinus (St. Leudwinus, Leutwinus, Lievin, Liutwin) (about 660 - 722), was Count and bishop of Trier, 697-715 or 685-704. His parents were Warinus, Count of Poitiers (638-677) and Kunza, perhaps daughter of Clodoule, Bishop of Metz. He was buried at Mettlach.
Rotrude of Treves who married Charles Martel, has been suggested to have been his daughter, and given the Chrod- element in her name (Chrodtrudis), it has been suggested that her mother, the wife of Leudwinus, may have been daughter or kinswoman of count Chrodobertus.
