Ninus (Greek: Νίνος), according to Greek historians writing in the Hellenistic period and later, was the founder of Nineveh (also called Νίνου πόλις "city of Ninus" in Greek), ancient capital of Assyria. What figure or figures he may have been based on is uncertain; an identification with Shamshi-Adad I, Shamshi-Adad V, and/or a conflation of the two has been suggested.
