Hanno I the Great (Punic: 𐤇‬𐤍‬𐤀‬‬, ḤNʾ) was a Carthaginian politician and military leader of the 4th century BC. The Roman historian Justin calls him princeps Carthaginiensium, prince of the Carthaginians. The title almost certainly signifies "first among equals", rather than noble or royal status. His rival, Suniatus, was called the potentissimus Poenorum, or "the most powerful of the Carthaginians", in the year 368. Several years later, Suniatus was accused of high treason (for correspondence with Syracuse) and probably executed.
