Nemea is an ancient site in the northeastern part of the Peloponnese, in Greece. Formerly part of the territory of Cleonae in ancient Argolis, it is today situated in the regional unit of Corinthia. The small village of Archaia Nemea is immediately southwest of the archaeological site, while the new town of Nemea lies to the west.
Here, in Greek mythology, Heracles overcame the Nemean Lion, and here, during Antiquity, the Nemean Games were held and were celebrated in the eleven Nemean odes of Pindar.
