Inzak was a Mesopotamian god worshipped by the people of Dilmun.[1] The ancient Sumerians regarded him as the chief god of the Dilmunite pantheon,[1] but the Dilmunites themselves regarded him as a god of Agaru, a land in eastern Arabia.[1] His main cult center was on Failaka Island,[1] where a temple was dedicated to him.[1] During the Neo-Babylonian Period, Inzak was identified with Nabu.[1]
