Hanun-Dagan (meaning "Dagan is merciful"; died 2008 BC), was the Shakkanakku and king (Lugal) of Mari, reigning c. 2016-2008 BC. He was the brother of his predecessor Hitlal-Erra, and is recorded as the son of Shakkanakku Puzur-Ishtar on a seal discovered in the city. Although the title of Shakkanakku designated a military governor, the title holders in Mari were independent monarchs, and nominally under the vassalage of the Ur III dynasty. Some Shakkanakkus used the royal title Lugal in their votive inscriptions, while using the title of Shakkanakku in their correspondence with the Ur's court
