Tamos (Ancient Greek: Ταμώς), was a mercenary Admiral from Memphis in Egypt, hired by Cyrus the Younger, during his campaign to claim the Persian Throne.
Tamos led a fleet of 25 triremes as a backup to Cyrus's mercenary Ten Thousand hoplites and Persian troops.
Tamos was Cyrus's secondary admiral, his first being Pythagoras the Spartan, who led the first fleet of 35 triremes.
Tamos mostly acted as a terror commander, sailing his fleet to hostile areas, quelling unrest by his mere presence.
Tamos first saw action when his fleet blockaded the city of Miletus when it allied itself with Artaxerxes II.
