Untash-Napirisha was king of Elam (in present-day southwest Iran) during the Middle Elamite period. He was the son of the previous Elamite king, Humban-Numena. He was named after Napir, the Elamite god of the moon.
He founded and built extensively a new city, Dur-Untash, 40 km SE of Susa, modern Chogha Zanbil. He built extensively in this city, and its main temple, the famous Ziggurat still stands there. Although construction in this religious city complex abruptly ended after Untash-Napirisha's death, the site was not abandoned, but continued to be occupied until it was destroyed by the Assyrian king Ashurbanipal in 640 BC.
A later Elamite letter from Berlin Pergamon Museum (VAT17020) mentions that he married to “the daughter of Burna-buriash (a Babylonian king) and she bore him a son (and the future Elamite king) Kidin-hudurdish (Hutran)". If this was the Babylonian king Burna-Buriash II, then the reign of Untash-Napirisha could be dated ca 1340 - 1300 BC. However, some scholars consider a different model for the synchronism between Kassite dynasty in Babylone and the Elamite kings, and suggest that the mentioned Burna-buriash was a later prince, and that the reign of Untash-Naprisha could be dated ca. 1275 - 1240 BC, see, for example
