Francisco Cortés Ojea (also spelled Hojea or Ojeda) was a 16th-century Spanish sailor and explorer who took part in the first expeditions sent from the General Captaincy of Chile to the Strait of Magellan. The times and places of his birth and death have not been documented. He was a map-maker with the expedition of Francisco de Ulloa sent in 1553 by the governor of Chile to survey the southern coast of the country and the Strait of Magellan. He later commanded the San Sebastián under the orders of captain Juan Ladrillero in the expedition sent in 1557 by governor García Hurtado de Mendoza.
