Ansbert (Latin: Ansbertus) was a Frankish Austrasian noble, as well as a Gallo-Roman Senator. He is thought to be the son of Ferreolus, Senator of Narbonne and his wife, Dode. This would make him the great-grandson of Tonantius Ferreolus, Praetorian Prefect of Gaul and his wife Papianilla. Little of his actual life is known. His wife Billihild was reputed to be a daughter of Charibert I (reigned 561–567), Merovingian King of Paris, and granddaughter of Chlothar I.
