Gonzalo Méndez de Canço (or "de Cancio", or "de Canzo") y Donlebún (c. 1554 – March 31, 1622) was a Spanish admiral who served as the seventh governor of the Spanish province of La Florida (1596-1603). He fought in the Battle of San Juan (1595) against the English admiral Francis Drake. During his tenure as governor of Florida, he dealt severely with a rebellion known as Juanillo´s revolt among the Native Americans in Guale, forcing them, as well as other tribes in Florida, to submit to Spanish domination. De Canço was best known, however, for promoting the cultivation of maize in the province, and for introducing its cultivation to Asturias, Spain, where it eventually became an important crop.
