Salina is an island in the Aeolian Islands (Italian: Isole Eolie, Sicilian: Ìsuli Eoli) north of Sicily, southern Italy. It is the second largest island in the archipelago.
Salina is divided between three comuni: Santa Marina on the eastern coast, Malfa to the north, and Leni to the south-west. From Leni down towards the sea is the village of Rinella, Sicily. Above the village of Leni is Valdichiesa in the center of the island. The other smaller villages are Capo Faro, Pollara and Lingua.
A Greek settlement, from the fourth century BC through to the times of Imperial Rome, once lay on the modern-day site of the small town of Santa Marina. A number of tombs from this era have been discovered further inland. Several traces of Greek and Roman culture have been found on the island.
In the Hellenic Age the island was named "Didyme" (Δίδυμη), a Greek name which refers to the two mountains as "twins". The island was inhabited as far back as the Bronze Age and has been developed and then abandoned many times over the subsequent millennia.
Areas on the island, including the two mountain peaks, were designated as a natural reserve in 1981.
