The Aegadian Islands (Italian: Isole Egadi; Sicilian: Ìsuli Ègadi; Latin: Aegates Insulae; Greek: Αιγάδες Νήσοι; lit. 'the islands of goats') are a group of five small mountainous islands in the Mediterranean Sea off the northwest coast of Sicily, Italy, near the cities of Trapani and Marsala, with a total area of 37.45 square kilometres (14.46 sq mi).
The island of Favignana (Aegusa), the largest, lies 16 kilometres (9.9 mi) southwest of Trapani; Levanzo (Phorbantia) lies 13 kilometres (8.1 mi) west; and Marettimo, the ancient Hiera Nesos, 24 kilometres (15 mi) west of Trapani, is now reckoned as a part of the group. There are also two minor islands, Formica (which hosts the Isolotto Formica Lighthouse) and Maraone, lying between Levanzo and Sicily. For administrative purposes the archipelago constitutes the comune of Favignana in the province of Trapani.
