Herakles Rallis (died 431 BC) was a Cephalonian bandit during the 5th century BC. In 431 BC, after Iraklis Mangas and Yiorgos Contos fled to the Cyclops of Kephallonia and told him that Kassandra had beaten them and not paid back Markos of Kephallonia's debts, the Cylops sent Herakles, Tolis Kontos, Minoas Leos, and a few other bandits to attack Kassandra on the road to Mount Ainos. Kassandra succeeded in slaying all the bandits.
