Calafia, or Califia, is the fictional queen of the Island of California, first introduced by 16th century poet Garci Rodríguez de Montalvo in his epic novel of chivalry, Las sergas de Esplandián, written around 1510. Rodríguez's fictional Californie is most likely the namesake of the California region encompassing the U.S. state of California and the Mexican states of Baja California and Baja California Sur.
