Haddu, was an ancient kingdom in northern Syria, identified with the modern Tell Malhat ed-Deru (تل مليحة الدور) in Deir ez-Zor Governorate. The kingdom flourished in the middle of the third millennium BC and controlled the middle Khabur valley. It was ruled by its own monarch who was a vassal of Ebla, and fought against the kingdom of Mari. The king of Haddu declared to Mari's ambassador that he "I and Ebla have a pact of peace. And the oath of the pact is before Kura (the main Eblaite god) and before Hadda".
