(Νῖνος), the eponymous founder of the city of Ninus or Nineveh, must be regarded as a mythical and not an historical personage. His exploits are so much mixed up with those of Semiramis, his wife, whose name was much more celebrated in antiquity, that we refer the account of Ninus to the article Semiramis. [SEMIRAMIS.]

There is also another Ninus, who is represented by some authorities as the last king of Nineveh, and the successor of Sardanapalus, who is usually described as the last king. See SARDANAPALUS.
