Diodotus Tryphon (Greek: Διόδοτος Τρύφων) was king of the Hellenistic Seleucid Empire. As a general of the army he promoted the claims of Antiochus VI Dionysus the infant son of Alexander Balas in Antioch after Alexander’s death but then in 142 deposed the child and himself seized power in Coele-Syria where Demetrius II Nicator was unpopular for his oppressive treatment of the Jews.
