(died 944) was the Count of Verdun
by inheritance and Duke of Lorraine
by appointment of Otto I, Holy Roman Emperor
. He was the son of Count Ricwin
and the count's first wife, who was probably a Liudolfing
. Thus, he was related to Otto, which simultaneously explains his name and his appointment to such high office.
Sometime between 940 and 942, he was appointed duke and given the guardianship over Henry, the son of Gilbert, the first duke of Lorraine. He died not long after and only shortly before Henry his ward. He is sometimes numbered Otto I because another Otto later ruled over Lower Lorraine.
