Charibert (also spelled Caribert and Heribert), Count of Laon, was the maternal grandfather of Charlemagne. He was the father of Charles's mother, Bertrada of Laon. Only his mother, Bertrada of Prüm, is known from contemporary records as the two signed the foundation act of the Abbey of Prüm in 721. The same year, also with his mother, he made a donation to the Abbey of Echternach. Charibert's father possibly was Martin of Laon. Charibert married Gisela d'Aquitaine by whom he had at least two daughters: Charibert died before 762, as stated in an act of his daughter and son-in-law.
