In Greek mythology, Adrastus or Adrestus (Ancient Greek: Ἄδραστος or Ἄδρηστος, perhaps meaning "the inescapable") was a king of Argos, and leader of the Seven against Thebes. He was the son of the Argive king Talaus, but was forced out of Argos by his dynastic rival Amphiaraus. He fled to Sicyon, where he became king. Later, he reconciled with Amphiaraus and returned to Argos as its king.
