Dumuzi-Abzu, in Mesopotamian religion, Sumerian deity, city goddess of Kinirsha near Lagash in the southeastern marshland region. She represented the power of fertility and new life in the marshes. Dumuzi-Abzu corresponded to the Sumerian god Dumuzi of the central Steppe area, and thus around Eridu she was viewed as male and as son of Enki (Akkadian: Ea, also called the Lord of Apsu).
