Hanno, fl. 250–200 BC, Carthaginian statesman, leader of the conservative land-owning party and consistent opponent of the Barca family. His refusal to pay the mercenaries of Hamilcar Barca brought on their great revolt (240–238 BC). He favored expansion in Africa (where he extended the Carthaginian conquests to Theveste) and opposed war with Rome. Hanno's unwillingness to send help overseas was a factor in Hannibal's final failure in Italy.
