Sîn-kāšid, inscribed EN.ZU-kà-ši-id, was the king of the ancient Mesopotamian city of Uruk during the first half of the 18th century BC. His precise dating is uncertain, perhaps ca. 1803–1770 BC ( short chronology) corresponding to ca.1865–1833 BC ( middle chronology), but likely to have been fairly long due to the voluminous building inscriptions extant for which he is best known and contemporary with Nur-Adad of Larsa (1801–1785 BC) and Enlil-bāni of Isin (ca. 1798–1775 BC). His apparent lack of relationship with any of the preceding rulers of Uruk and his omission of mentioning his father in any of his inscriptions has led to the belief that he was the founder of a dynasty. He participated in a diplomatic marriage with Šallurtum, the daughter of Sūmû-la-Il (ca. 1817–1781 BC), the second king of the First Babylonian Dynasty, as her name and epithets appear in the seal impressions of three clay bullae recovered from the remains of his palace.
