Kalydon (Greek: Καλυδών) is an uninhabited island area near to and belonging to Elounda, Crete, Greece.

The term Kalydon is often applied to each of the Spinalonga islands as their alternate historic name that was further re-established in modern Greek naming, whilst Spinalonga is still the preferred naming in the public.

In 1834, a population of 81 Muslim families is attested in the area.

After the 1866 revolution a lot of other Cretan Muslims from other areas moved in.

When the island Spinalonga became a leper colony in 1903, the last Turks left the place.
