Treasure Island (French: L'île au trésor) is a 1986 fabulist metafiction film directed by Chilean filmmaker Raúl Ruiz, which was screened in the Un Certain Regard section of the 1991 Cannes Film Festival. French, British and American companies funded Ruiz's obscure and complex adaptation of the classic 1883 coming-of-age adventure novel by Robert Louis Stevenson. Treasure Island stars a young Melvil Poupaud, a familiar face in Ruiz's filmography, alongside popular veteran actors such as Martin Landau, Anna Karina and Jean-Pierre Léaud.

The film's play on the traditional narrative of an iconic and frequently dramatized story is very representative of Ruiz' oneiric approach and style. Ruiz takes his fondness for cartography to a new level with Stevenson's narrative, making the book into a map to the treasure in this rendition.
