Arna (Greek: Άρνα) is a village on the eastern slopes of the Taygetus mountain range, at an altitude of 700 to 850 m (2,300 to 2,790 ft).

Located in Laconia, in the Peloponnese, it used to form part of the municipal unit of Faris until 31 December 2010.

These findings support the conclusion that the site has been, since ancient times, a stop on the road connecting Sparta and Messenia.

Folk tradition has it that Constantine Kolokotronis (father of famed hero Theodoros Kolokotronis) sought refuge in this cave after being wounded defending the tower of the nearby village of Kastania, at the side of fellow revolutionary Panagiotaros Venetsanakos, a Maniot from Mesa Mani.

There are, however, positive signs of increased activity: the number of visits from emigrant Arniotes is on the rise year-round.
