Ruhurater or Lahuratil was an Elamite deity.
Ruhurater's gender is uncertain, though some researchers refer to him as a male deity. It has been proposed that his name means "(the god who is the) creator (of) man" and that he was connected to various creator deities (collectively known as Napratep), but his role in Elamite beliefs remains uncertain. It is possible that he was regarded as a creator deity in a specific area of Elam, but not in the entire region.
Many documents mentioning Ruhurater are legal texts which cast him in the role of a divine witness, alongside the Mesopotamian Shamash. He is also described as capable of bestowing kiten, an Elamite religious concept which can be translated as "divine protection." Wouter Henkelman notes that his role in them can be compared to that played by Inshushinak in similar texts from Susa.
The oldest attestion of Ruhutater comes from, possibly to be identified with the ancient Elamite city of Huhnur. The text in mention, an inscription of Amar-Sin, a Mesopotamian king from the Third Dynasty of Ur, states that Huhnur was the cult center of this god. Amar-Sin apparently rebuilt Ruhurater's temple located there and returned a statue of the god to it. Association between him and Huhnur is also attested in two texts from the Sukkalmah period. Another temple of Ruhurater, shared with Hishmitik, was located at Chogha Zanbil. It has been proposed that Hishmitik was his spouse, but this remains unproven.
Two Elamite kings bore the theophoric name Tan-Ruhurater, "obedient to Ruhurater." Tan-Ruhurater I was the eighth ruler from the Shimashki dynasty, while Tan-Ruhurater II belonged to the Kidinuid dynasty.
Ruhurater is mentioned on a stele of the neo-Elamite king Atta-hamiti-Insushinak, who reigned in the sixth century BCE. While Ruhurater is not directly mentioned in the Persepolis Administrative Archives, it is possible that offerings to unspecified gods made in Huhnur mentioned in it constituted an Achaemenid continuation of his cult.
In Mesopotamian scholarly texts, Ruhurater was considered to be an equivalent of Ninurta.
An Elamite bearing a theophoric name invoking Ruhurater, Kutir-Ruhurater, is also mentioned in records from archives of the Mesopotamian First Sealand dynasty.
