(Εὐθίας), an Athenian orator of the time of Demosthenes. He brought an accusation against Phryne, and as he filed in his attempt to bring about her condemnation, he abstained ever after from speaking in the courts of justice. (Athen. 13.590; Alciphr. Epiist. 1.10, &c.; Suidas. s. v. Εὐθίας; Schol. ad Hermog. p. 45.)
