The Chincha were a Native American people of the Andes. They are discussed by Maria Rostworowski de Diez Canseco in "History of the Inca Realm" (Cambridge University Press, 1999) and by Justo Caceres Macedo in "Prehispanic Cultures of Peru" (Peruvian Natural History Museum, 1985). Friedrich Ratzel in The History of Mankind[1] reported in 1896 that Francisco Pizarro met with the Chinchas who had traditions of a distant home across the sea.
They have given their name to the Chincha Islands, off the coast of Peru, as well as the animal known as the chinchilla (literally "Little Chincha"). The Chincha were eventually overrun by the Incas.
