Kaštiliašu III, phonetically inscribed incuneiform as^mKaš-til-ia-šu, was a possibleKassite king ofBabylonia in the 15th century BC (Short Chronology). He is known only from the Assyrian Synchronistic King List,^{[i 1]} a copy of a monumental inscription,^{[i 2]} his genealogy, and references in theChronicle of Early Kings.^{[i 3]}

Evidence of Kaštiliašu's kingship is circumstantial. He may be the individual indicated on line 21^{[nb 1]} of the Synchronistic King List^{[i 1][1]} where he is placed opposite Assyrian kingAššur-nārāri I and is preceded by a lacuna and succeeded by a poorly preserved name not thought to beUlam-Buriaš.^[2] Two passages in theChronicle of Early Kings mention Kaštiliašu: "Ulam-Buriaš, brother of Kaštiliašu, the Kassite" and "Agum, the son of Kaštiliašu".^{[i 3][3]} Ulam-Buriaš conquered and ruled the Sealand—at the southern end of Babylonia—and perhaps ruled as king of Babylonia, while Agum III was king of Babylonia. Kaštiliašu has no royal title in those passages, a feature of this chronicle shared by others, such asSamsu-Ditana, who, despite lacking monarchical epithets, proved to be kings.^[1]

A recently published copy of a monumental inscription^{[i 2]} celebrates his excavation of the Sumundar Canal and confirms his genealogy as the son ofBurnaburiaš I,^{[nb 2]} and grandson ofAgum II. It describes his ritual use of a silver spade and basket, which were subsequently displayed in the temple ofEnlil, and his conscription of the people and land ofYamutbal for the excavation. Although he is designated asšakkanak Enlil, “governor of Enlil”, the title and subsequent elaborate curse formula against those who might later efface the inscription implies his regnal status.^[4]
