The Treaty of Ribemont was a dynastic treaty concluded in the city of Ribemont in February 880, between the East Frankish king Louis the Younger, and his cousins, West Frankish kings Louis III and Carloman II. The treaty secured concord between two branches of the Carolingian dynasty, and also confirmed previously agreed (879) transfer of the western half of Lotharingia from the West Frankish jurisdiction to the East Frankish king, who already ruled over eastern Lotharingian regions.
