Kalamata is the second most populous city of the Peloponnese peninsula, after Patras, in southern Greece and the largest city of the homonymous administrative region. As the capital and chief port of the Messenia regional unit, it lies along the Nedon River at the head of the Messenian Gulf.

The Peloponnese, Peloponnesus or Morea is a peninsula and geographic region in Southern Greece, and the southernmost region of the Balkans. It is connected to the central part of the country by the Isthmus of Corinth land bridge which separates the Gulf of Corinth from the Saronic Gulf. From the late Middle Ages until the 19th century, the peninsula was known as the Morea, a name still in colloquial use in its demotic form.
