Kadašman-Enlil I, typically rendered mka-dáš-man-dEN.LÍL in contemporary inscriptions, was a Kassite King of Babylon from ca. 1374 BC to 1360 BC, perhaps the 18th of the dynasty. He is known to have been a contemporary of Amenhotep III of Egypt, with whom he corresponded. This places Kadašman-Enlil securely to the first half of the 14th century BC by most standard chronologies.

Amenhotep III, also known as Amenhotep the Magnificent or Amenhotep the Great and Hellenized as Amenophis III, was the ninth pharaoh of the Eighteenth Dynasty. According to different authors, he ruled Egypt from June 1386 to 1349 BC, or from June 1388 BC to December 1351 BC/1350 BC, after his father Thutmose IV died. Amenhotep was Thutmose's son by a minor wife, Mutemwiya.
