'Book of the Marvels of the World' (French: Livre des Merveilles du Monde) or 'Description of the World' (Devisement du Monde), in Italian Il Milione ('The Million') or Oriente Poliano and in English commonly called 'The Travels of Marco Polo', is a 13th-century travelogue.

It was recorded by Rustichello da Pisa from stories told by Marco Polo, describing Polo's travels through Asia between 1276 and 1291, and his experiences at the court of Kublai Khan.
