Akalamdug (𒀀𒌦𒄭, A-KALAM-DUG) was an early ruler of the First Dynasty of Ur in the 26th century BCE. He does not appear in the Sumerian King List, but is known from his tomb (Tomb 1332) and an inscription at the Royal Cemetery at Ur. He may have been the father of Meskalamdug, as suggested by the similarity of their names and the chronological proximity of their graves. Alternatively, he may have been the son of Meskalamdug, and therefore brother of the great ruler Mesannepada.
