Itūr-Mēr was a Mesopotamian god worshiped in the kingdom of Mari, and after its fall in the kingdom of Khana, especially in Terqa. His name is structured like a theophoric name rather than a typical theonym, which lead to the proposal that he was originally a deified hero or ancestral figure. An alternative theory considers him a hypostasis of the god Mēr, though unlike him he was not a weather deity.
