Giraglia is a French island at the northern tip of Corsica in the Mediterranean Sea, known for its powerful lighthouse and for the Torra di Giraglia, a Genoese tower, both of which are official historical monuments of France.
The Giraglia Rolex Cup, an annual keelboat regatta, was named for the island. The race starts in St. Tropez, France, passes through the Îles d'Hyères near Giraglia, and then finishes off in Genoa, Italy, a total distance of .
The island is part of the commune of Ersa, although there are no settlements on the island. The closest are Tollare, Ersa commune, and Barcaggio, Rogliano commune, on the main island of Corsica.
The lighthouse was first constructed in 1573 by the Genovese, but has been rebuilt several times since.
