Elis or Ilia (Greek: Ηλεία, Ileia) is a historic region in the western part of the Peloponnese peninsula of Greece. It is administered as a regional unit of the modern region of Western Greece. Its capital is Pyrgos. Until 2011 it was Elis Prefecture, covering the same territory.

The modern regional unit is nearly coterminous with the ancient Elis of the classical period. Here lie the ancient ruins of cities of Elis, Epitalion and Olympia, known for the ancient Olympic Games which started in 776 BC.
