Fatu-Hiva - Back to Nature is a book published in 1974 by archaeologist and explorer Thor Heyerdahl detailing his experiences and reflections during a 15-month stay on the Marquesan island of Fatu Hiva in 1937–38. The book was based on Heyerdahl's original report På Jakt efter Paradiset (In Search of Paradise), which was published in Norway in 1938, but because of the outbreak of World War II was never translated and rather forgotten.
