Giovanni Andrea Doria, also Giannandrea Doria (1539–1606), was an Italian admiral from Genoa. He was the son of Giannettino Doria and the great-nephew of the famed Genoese admiral Andrea Doria, by whom he was later adopted. He became the Admiral of the Genoese Fleet in 1556, and commanded the combined Christian fleet of the Holy League at the Battle of Djerba in 1560, which was won by the Ottoman Turks under the command of Piyale Pasha. He also participated in the Battle of Lepanto (1571), which was won by the Christian forces and signaled the first ever defeat of the Ottoman Turks at sea.
He was the father of the cardinal Giovanni Doria.
