Antipsara (Greek: Αντίψαρα) is a small, Greek island in the Aegean Sea. Antipsara had 4 inhabitants according to the 2011 census. It lies about 3 km (2 mi) west of the larger island Psara, from which its name is derived. Geographic conditions make it inaccessible from the north and west side. Evidence exists of settlement in ancient Greek and Roman times. During the Ottoman rule the island served as port. Nowadays, tourist trips to the island originate from Psara in the summer months.
