Heliaia or Heliaea (; Doric: Ἁλία "Halia") was the supreme court of ancient Athens. The view generally held among scholars is that the court drew its name from the ancient Greek verb , which means , namely "congregate". Another version is that the court took its name from the fact that the hearings were taking place outdoors, under the sun. Initially, this was the name of the place where the hearings were convoked, but later this appellation included the court as well.
