(Δικαιογένης), a Grecian tragic and dithyrambic poet, of whom nothing is known except a few titles of his dramas. One of these, the Cypria, is supposed by some to have been not a tragedy, but a cyclic epic poem. (Suid. s.v. Aristot. Poet. 16, with Ritter's note, p. 199; Fabric. Bibl. Graec. ii. p. 295.)
