Enmebaragesi (Sumerian: 𒂗𒈨𒁈𒄄𒋛 Enmebárgisi [EN-ME-BARA2-GI4-SE]) originally Mebarasi (𒈨𒁈𒋛) was the penultimate king of the first dynasty of Kish and is recorded as having reigned 900 years in the Sumerian King List. Like his son and successor Aga he reigned during a period when Kish had hegemony over Sumer.a Enmebaragesi signals a momentous documentary leap from mytho-history to history, since he is the earliest ruler on the king list whose name is attested directly from archaeology.

Kish is an important archaeological site in Babil Governorate (Iraq), located 80 km (50 mi) south of Baghdad and 12 km (7.5 mi) east of the ancient city of Babylon. The Ubaid period site of Ras al-Amiyah is 8 km (5.0 mi) away. It was occupied from the Ubaid period to the Hellenistic period. In Early Dynastic times the city's patron deity was Ishtar with her consort Ea. Her temple, at Tell Ingharra, was (E)-hursag-kalama. By Old Babylonian times the patron deities had become Zababa, along with his consort, the goddess Bau and Istar. His temple Emeteursag was at Uhaimir.
