Federico Cornaro or Corner (died 1382) was a 14th-century Venetian patrician, merchant and politician. In 1379, he was accounted the richest man in Venice, having become wealthy from his sugar plantations in Cyprus. He used this wealth to buy his son a marriage with the heiress of the Lordship of Argos and Nauplia in Greece, which he de facto ruled in their name until his death.
