Astros (Greek: Άστρος or Μεσόγειο Άστρος, "Inland Astros") is a town near the Argolic Gulf in the northeast Peloponnese in eastern Arcadia. Astros is the seat of North Kynouria municipality (Greek: Βόρεια Κυνουρία). The name of the town, built during the Greek War of Independence, is supposed to be taken from the ancient settlement Astron, mentioned in Ptolemy's Geography. Astros is accessible by the road connecting Tripoli and Argos and Tyros and Leonidio and Monemvasia to the south. Its port, Paralio Astros lies 4 km to the northeast of the inland town.
Astros was the site of the Second National Assembly of the Hellenes during the Greek War of Independence, under the presidency of Petros Mavromichalis. This assembly produced the first constitution of Modern Greece.
Astros has a school, a lyceum, a high school, a number of churches including one which is situated on a hilltop, banks, and a post office. There is a health clinic on the road to Leonidio. There are a number of squares (plateies), the most westerly of which contains a small amphitheater built into the hillside.
Much of the land is rocky and bushy and unsuitable for cultivation, but there are some farms and groves in low-lying areas near town.
