The Battle of Nemea (394 BC) was a battle in the Corinthian War, between Sparta and the allied cities of Argos, Athens, Corinth, and Thebes. The battle was fought in Corinthian territory, at the dry bed of the Nemea River. The battle was a decisive Spartan victory, which, coupled with the Battle of Coronea later in the same year, gave Sparta the advantage in the early fighting on the Greek mainland.
