Eurybiades () was the Spartan commander in charge of the Greek navy during the Second Persian invasion of Greece (480-479 BC). He was the son of Eurycleides, and was chosen as commander in 480 BC because the Peloponnesian city-states led by Sparta, worried about the growing power of Athens, did not want to serve under an Athenian despite the Athenians' superior naval skill. Despite the enmity between the two, Eurybiades was assisted by the Athenian naval commander Themistocles.
