Dur-Kurigalzu was a city in southern Mesopotamia, near the confluence of the Tigris and Diyala rivers, about 30 kilometres (19 mi) west of the center of Baghdad. It was founded by a Kassite king of Babylon, Kurigalzu I and was abandoned after the fall of the Kassite dynasty. The city was of such importance that it appeared on toponym lists in the funerary temple of the Egyptian pharaoh, Amenophis III at Kom el-Hettan". The prefix Dur is an Akkadian term meaning "fortress of", while the Kassite royal name Kurigalzu is believed to have meant "shepherd of the Kassites". The tradition of naming new towns Dur dates back to the Old Babylonian period with an example being Dūr-Ammī-ditāna. The city contained a ziggurat and temples dedicated to Mesopotamian gods, as well as a royal palace which covered 420,000 square meters.

Kurigalzu I, usually inscribed ku-ri-gal-zu but also sometimes with the m or d determinative, the 17th king of the Kassite or 3rd dynasty that ruled over Babylon, was responsible for one of the most extensive and widespread building programs for which evidence has survived in Babylonia. The autobiography of Kurigalzu is one of the inscriptions which record that he was the son of Kadašman-Ḫarbe. Galzu, whose possible native pronunciation was gal-du or gal-šu, was the name by which the Kassites called themselves and Kurigalzu may mean Shepherd of the Kassites.
