Francesco Erizzo (Venice, February 18, 1566 – Venice, January 3, 1646) was the 98th Doge of Venice, reigning from his election on April 10, 1631 until his death fifteen years later. His reign is particularly notable because the last year of his reign saw the beginning of a war with the Ottoman Empire for control of Crete that would last for 24 years (1645–1669) and dominate the geopolitics of the Mediterranean.
