Francisco de Ulloa (pronounced [fɾanˈθisko ðe wˈʎoa]) (died 1540) was a Spanish explorer who explored the west coast of present-day Mexico and the Baja California Peninsula under the commission of Hernán Cortés. Ulloa's voyage was among the first to disprove the cartographic misconception of the existence of the Island of California.
