Aeaces (Ancient Greek: Αἰάκης, fl. 550 BC) was the father of Polycrates, the powerful tyrant of Samos. He was a prominent aristocrat in his own right, and may even have been the ruler of the island for a period in the mid-sixth century. He is sometimes referred to as Aeaces I to distinguish him from his grandson Aeaces II, who ruled Samos in the late sixth and early fifth centuries BC.
