Antisthenes of Sparta was a Spartan admiral in the Peloponnesian war, who was sent out in 412 BC, in command of a squadron, to the coast of Asia Minor, and was to have succeeded Astyochus, in case the Spartan commissioners thought it necessary to deprive that officer of his command. We hear of him again in 399 BC, when, with two other commissioners, he was sent out to inspect the state of affairs in Asia, and announce to Dercyllidas that his command was to be prolonged for another year. There was also an Athenian general called Antisthenes.
