Erridupizir

Erridupizir (Erridu-pizir)  (fl. 2141–2138 BC (Short chronology)) was a Gutian ruler in Sumer. His reign was attested by a royal inscription at the archaeological site for the ancient city-state of Nippur where he called himself: "King of Guti, King of the Four Quarters" Thought to be the "king without a name" on the SKL. Imta then succeeded Erridupizir.

After the Akkadian Empire fell to the Gutians, the Lullubians rebelled against Erridupizir, according to the latter's inscriptions:

"Ka-Nisba, king of Simurrum, instigated the people of Simurrum and Lullubi to revolt. Amnili, general of [the enemy Lullubi]... made the land [rebel]... Erridu-pizir, the mighty, king of Gutium and of the four quarters hastened [to confront] him... In a single day he captured the pass of Urbillum at Mount Mummum. Further, he captured Nirishuha."

- Inscription R2:226-7 of Erridupizir.

In another inscription he said "the goddess Aštar had stationed troops in Agade".
