Erridupizir was a Gutian ruler in Sumer from ca. 2141 BC to 2138 BC (short chronology). His reign is attested by a royal inscription at Nippur where he calls himself "King of Guti, King of the Four Quarters." His inscriptions indicate that after the Akkadian Empire fell to the Gutians, the Lullubi rebelled against Erridupizir.
