Isola del Giglio is an Italian island in the Tyrrhenian Sea (one of seven that form the Tuscan Archipelago, lying within the Arcipelago Toscano National Park), and is part of the province of Grosseto. The island is separated by a 16 km of sea from the nearest point of the mainland, the promontory of Monte Argentario. Mainly mountainous, it consists almost entirely of granite, culminating in the Poggio della Pagana (496 m).
On 13 January 2012, the cruise liner Costa Concordia ran aground just off the island shore. Most of the more than 4,200 passengers and crew were rescued and taken to the island, as well as to the mainland. At least 30 people died.
Three principal settlements are located on the island:
- Giglio Porto is located on the eastern coastal side and hosts the port.
- Giglio Castello is located upon a hill between the two other localities and is characterised by the majestic walls of a fortress
- Giglio Campese is located on the north-western coastal side and is a modern sea resort
