Kubaba, or Kug-Baba, is the name of the only Queen in the Sumerian king list.
Her reign as the only "king" of the 3rd Dynasty of Kish was one of peace and prosperity. Her reign is contemporary with the "Early Dynastic III" period of Sumer. Her reign is listed to have lasted for 100 years.

Kubaba was the tutelary goddess who protected the ancient Syrian city of Carchemish. Her cult spread, and her name was adapted for the main goddess of the Hittite successor-kingdoms in Anatolia, and later developed into Phrygian Cybele.

Phrygian inscriptions with her image in rock-cut sculptures identify her as matar ("mother") and, in one instance matar kubileya.
The Phrygian goddess otherwise bears little resemblance to Kubaba, who was a sovereign deity at Sardis, known to Greeks as Kybebe.

Shrines in her honour spread throughout Mesopotamia. In the Hurrian area she may be identified with Kebat, or Hepat, one title of the Hurrian Mother Goddess Hannahannah (from Hurrian hannah, "mother").

In the Aramaean period that followed, Heba became Hawah, the Syrian snake Goddess and mother of all living, who emerged in the Bible as Eve.
