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 (The Adventures of Esplandián), written around 1510. The Californias, a region of North America encompassing the U.S. state of California and the Mexican states of Baja California and Baja California Sur, take their name from Calafia and her kingdom.
