Andrea Doria (or D'Oria) (30 November 1466 – 25 November 1560) was an Italian condottiere and admiral from Genoa.
Doria was born at Oneglia from the ancient Genoese family, the Doria di Oneglia branch of the old Doria, de Oria or de Auria family. His parents were related: Ceva Doria, co-lord of Oneglia, and Caracosa Doria, of the Doria di Dolceacqua branch. Orphaned at an early age, he became a soldier of fortune, serving first in the papal guard and then under various Italian princes.
In 1503 he was fighting in Corsica in the service of Genoa, at that time under French vassalage, and he took part in the rising of Genoa against the French, whom he compelled to evacuate the city. From that time onwards, he became famous as a naval commander. For several years he scoured the Mediterranean in command of the Genoese fleet, waging war on the Turks and the Barbary pirates.
