The Peloponnese, Peloponnesos, or Peloponnesus is a large peninsula, located in a region of southern Greece, forming the part of the country south of the Gulf of Corinth. During the late Middle Ages and the Ottoman era, the peninsula was known as the Morea (Greek: Μωρέας, colloq. Μωριάς), a name still in colloquial use. The peninsula is divided among three regions of Greece: most of it belongs to the Peloponnese region, and parts belong to the West Greece and Attica regions.
