Shu-turul (Shu-durul, , shu-tur2-ul3 also à  u-Turul; died 2154 BC) was the last king of Akkad, ruling for 15 years according to the Sumerian king list. It indicates that he succeeded his father Dudu. A few artifacts, seal impressions etc. attest that he held sway over a greatly reduced Akkadian territory that included Kish, Tutub, Nippur, and Eshnunna. The Diyala River also bore the name "Shu-durul" at the time.
The king list asserts that Akkad was then conquered, and the hegemony returned to Uruk following his reign. It further lists six names of an Uruk dynasty; however only two of these six rulers, Ur-nigin and Ur-gigir, have been confirmed through archaeology. With Akkad's collapse, the Gutians, who had established their capital at Adab, became the regional power, though several of the southern city-states such as Uruk, Ur, and Lagash also declared independence around this time.
A few inscriptions in his name are known. One, on an administrative clay sealing found at Kish reads:
A clay sealing of Shu-turl was found at Nippur. Another reading "[S]u-Turul, the [m]ighty, [ki]ng of [Aga]de: ... [(is) his servant]." was found at Tell Asmar.
A votive mace, made of dark green marble, is also known with an inscription mentioning Shu-turul and the dedication of a temple to Nergal:
A 17 centimeter long copper axe, acquired on the antiquities market, reads "Su-Turul, the mighty, king of Agade".
A tablet found at Adab contains the year name "year when Shu-Durul assumed the kingdom".
A one manna weight (in the shape of a duck), now held at the Urfa Museum, is inscribed with the name of an official of Akkadian ruler Shu-durul was recovered from a looted context in Titris Hoyuk.
