The Lenaia or Lenaea (Ancient Greek: Λήναια) was an annual Athenian festival with a dramatic competition. It was one of the lesser festivals of Athens and Ionia in ancient Greece. The Lenaia took place in Athens in Gamelion, roughly corresponding to January. The festival was in honour of Dionysus Lenaios. There is also evidence the festival also took place in Delphi. "Lenaia" probably comes from "lenos" 'winepress' or from "lenai", another name for the Maenads (the female worshippers of Dionysus).
