Ἄντανδρος), brother of Agathocles, king of Syracuse, was a commander of the troops sent by the Syracusans to the relief of Cro tona when besieged by the Brutii in B. C. 317. During his brother's absence in Africa (B. C. 310), he was left together with Erymnon in command of Syracuse, and wished to surrender it to Hamilcar. He appears, however, to have still retained, or at least regained, the confidence of Agathocles, for he is mentioned afterwards as the instrument of his brother's cruelty. (Diod. 19.3, 20.16, 72.) Antander was the author of an historical work, which Diodorus quotes. (Exc. 21.12, p. 492, ed. Wess.)
