Friday, or, The Other Island

Friday, or, The Other Island (French: Vendredi ou les Limbes du Pacifique) is a 1967 novel by French writer Michel Tournier. It retells Daniel Defoe's Robinson Crusoe.

The first edition of the book was published 15 March 1967. It won that year's Grand Prix du roman de l'Académie française. The book ranks 55th on Le Monde's 100 Books of the Century, a list of the one hundred most memorable books of the 20th century, a poll performed during the spring of 1999 by the French retailer Fnac and the Paris newspaper Le Monde.

In 1971, Tournier rewrote the book, adapting it for younger readers, under the title Vendredi ou la Vie sauvage.
