Juana Enriquez (1425-13 February, 1468), was the second wife of John II of Aragon. She was a Castilian noblewoman. She was a daughter of Fadrique Enríquez, Count of Melba and Rueda and Mariana de Córdoba. Juana Enriquez gave birth to Fernando II of Aragon who was chosen over his half-brother, Carlos of Viana to rule Aragon. Fernando married Isabella of Castile who inherited the throne from her half-brother, Henry IV of Castile. Henry's first wife was Fernando's half-sister by John's first wife, Blanca of Navarre (1420-1464). Juana then gave birth to Infanta Juana of Aragon who married Ferdinand I of Naples. By Fernando II of Aragon, Juana Enriquez was a forebearer of most of European royalty.
