Claros was an ancient Greek sanctuary on the coast of Ionia. It contained a temple and oracle of Apollo, honored here as Apollo Clarius. It was located on the territory of Colophon, one of the twelve Ionic cities, twelve kilometers to the north. The coastal city Notion lay two kilometers to the south. The ruins of the sanctuary are now found north of the modern town Ahmetbeyli in the Menderes district of Izmir Province, Turkey.
The Temple of Apollo at Claros was a very important center of prophecy as in Delphi and Didyma. The oldest information about this sacred site goes back to the sixth and seventh centuries BC. through the Homeric Hymns. A sacred cave near the Temple of Apollo, which was an important place both in the Hellenistic and Roman eras, points to the existence of a Cybele cult in earlier periods here. Games called the Claria were held at Claros every fifth year in honor of Apollo.
