Idalion (Greek Ιδάλιον) is an ancient city in Cyprus, famous for the temple of Aphrodite (one of the epithets of the goddess is Idalia). The inhabitants of the city revered Aphrodite as the main deity.

Idalion was located near the modern city of Dali in the Nicosia region. In ancient times, it was one of the ten city-states on the island, which are mentioned in the annals (tablets) of the Assyrian king Esarhaddon (680-669 BC).
