Alduin (Langobardic: Aldwin or Hildwin, Latin: Audoinus; also called Auduin or Audoin) was king of the Lombards from 546 to 560. Under him the Lombards became fœderati of the Byzantines (541), signing a treaty with Justinian I which gave them power in Pannonia and the north. Beginning in 551, Audoin was obliged to send troops to serve Narses in Italy in the Gothic War against the Ostrogoths. The next year (552), he sent over 5,000 men to defeat the Goths on the slopes of Vesuvius. That same year Audoin had been able to inflict a heavy defeat on the Gepids with the help of his brother-in-law Amalafrid: the Gepid king Thurisind lost his eldest son, Turismod, in the Battle of Asfeld during which the prince was killed by Alboin, son of Audoin.
He died in 563 or 565 and was succeeded by his son, Alboin, who brought the Lombards into Italia.
