Adalgis (died 788) was the son of Desiderius and the prince of the Langobards or Lombardia in Italy. After his father was defeated by Charlemagne in Pavia in 774, Adalgis took refuge in Byzantium. He hoped to recapture Lombardia with the aid of Empress Irene, but when finally given a chance in 787, he was defeated by a coalition consisting of the Franks and the new prince of Benevento, Grimoald III, a vassal loyal to Charlemagne. Adalgis fled to Constantinople, where he died in 788.
