Antipsara (Greek, Modern (1453-);: Αντίψαρα) is a small Greek island in the Aegean Sea. Antipsara had no permanent inhabitants, according to the 2021 census.[1] It lies about 3km (02miles) west of the larger Psara island, from which its name is derived. Geographic conditions make it inaccessible from the north and west sides. Evidence exists of settlement in ancient Greek and Roman times. During Ottoman rule the island served as a port. Nowadays, tourist trips to the island originate from Psara in the summer months. The small church of St John (Άγιος Ιωάννης) on the eastern side is visited in August by pilgrims.
The island is a nesting site of the European shag (Phalacrocorax aristotelis), Eleonora's falcon (Falco eleonorae), Cory's shearwater (Calonectris diomedea), and the yelkouan shearwater (Puffinus yelkouan).
