Milku was a god associated with the underworld who was worshiped in the kingdoms of Ugarit and Amurru in the late Bronze Age. It is possible that he originated further south, as Ugaritic texts indicate he was worshiped in cities located in the northern part of the Transjordan region. He was also incorporated into the Hurrian pantheon under the name Milkunni. There is also evidence that he was worshiped in Hittite religion. It is possible that a closely related deity is also known from Mesopotamia.
