Juana Enriquez de Córdoba, 5th Lady of Casarrubios del Monte (1425 – 13 February 1468, Tarragona), a Castilian noblewoman, was styled Queen of Navarre from her marriage in April 1444 to John II of Aragon and Navarre and was Queen consort of the Kingdoms of the Crown of Aragon from the death of her brother-in-law, King Alfonso V of Aragon, in 1458, until her own death. She married John three years after the death of his first wife, Queen Blanche I of Navarre.


She was a daughter of Fadrique Enríquez de Mendoza and Mariana Fernández de Córdoba y Ayala, 4th Lady of Casarrubios del Monte, and succeeded her mother in 1431. Born in Torrelobatón, she was a great-great granddaughter of Alfonso XI of Castile.

Coat of Arms

Although John ceased to be de jure uxoris monarch of Navarre on his wife's death, he never ceded power to his son, Charles, Prince of Viana, and daughter, de jure Blanche II of Navarre, a decision which Juana supported. Such breaking of the law of succession led to a confrontation with the Crown of Aragon and a conflict between farmers and nobles, the outbreak of Navarrese Civil War. Accused of having ordered the poisoning of Carlos, her stepson, who died in 1461, Juana fled to Girona, seeking the protection of the bishop.
