Eunomus (Ancient Greek: Εὔνομος) was an Athenian admiral during the Corinthian War.
[1] Eunomus encountered Gorgopas as he was sailing back to Aegina from Ephesus.
After unsuccessfully trying to bait Gorgopas to come out and fight, the Athenians sailed away at night fall.
He was able to surprise the Athenian fleet as it passed close to shore around Cape Zoster.
The Spartans captured four triremes and forced the rest of the Athenian ships to retreat to Piraeus.
