The Battle of the Great plains (also known as Battle of Campi Magni, Battle of Bagrades) is a battle fought between Scipio Africanus of Rome and a combined Carthaginian and Numidian army late in the Second Punic War, designed as diversionary tactic by Rome to disrupt Hannibal's attack on Italy.

By defeating the Carthaginians, Scipio Africanus causes Hannibal to leave Italy and return to Africa, where he is later defeated at the battle of Zama.
