The Etichonids were an important noble family, probably of Frankish or Burgundian origin, who rose to dominate the region of Alsace in the Early Middle Ages from the seventh to the tenth centuries.

Among the descendants of the Etichonids, in the female line were Hugh of Tours and his family, including his daughter Ermengard, who was wife to Lothair I and thus mother to three Carolingian kings.
