Nemea (nē´mēə, nĬmē´ə), city of ancient Greece, in N Argolis. At the temple of Zeus were held the Nemean games, which from 573 BC were one of the four Panhellenic festivals; the games were held in the second and fourth years of each Olympiad. Of Pindar's odes, 11 celebrate Nemean victories. The temple and palaestra have been excavated. Nemea is also the name of a river that formed the boundary of Corinth and Sicyon (near modern Sikión).
