Nagidos was an ancient city of Cilicia. In ancient times it was located between Anemurion to the west and Arsinoe to the east. Today its ruins are found on the hill named Paşabeleni at the mouth of the Sini Cay near Bozyazı in Mersin Province, Turkey. It lies at a distance of ca. 20 km to the east of Anamur. Like its eastern neighbor Kelenderis, it was a colony of Samos. The small island of Nagidoussa is opposite Nagidos; on it are the ruins of an Ottoman fortress.

Samos is a Greek island in the eastern Aegean Sea, south of Chios, north of Patmos and the Dodecanese archipelago, and off the coast of western Turkey, from which it is separated by the 1.6-kilometre-wide (1.0 mi) Mycale Strait. It is also a separate regional unit of the North Aegean region.
