Myus (Ancient Greek: Μυοuς), sometimes Myous or Myos, was an ancient Greek city in Caria. It was one of twelve major settlements of the Ionian League. The city was said to have been founded by Cyaretus (sometimes called Cydrelus), a son of Codrus. Myus was located on a small peninsula at the coast of the Aegean Sea, but it now lies inland due the sediment deposited by the Maeander River over many centuries.
