Peter Pan is a character created by Scottish novelist and playwright J. M. Barrie (1860–1937). A mischievous boy who can fly and magically refuses to grow up, Peter Pan spends his never-ending childhood adventuring on the small island of Neverland as the leader of his gang the Lost Boys, interacting with mermaids, Indians, fairies and pirates, and from time to time meeting ordinary children from the world outside. In addition to two distinct works by Barrie, the character has been featured in a variety of media and merchandise, both adapting and expanding on Barrie's works.

Peter Pan first appeared in a section of The Little White Bird, a 1902 novel written for adults. Following the highly successful debut of the play about Peter Pan in 1904, Barrie's publishers, Hodder and Stoughton, extracted chapters 13-18 of The Little White Bird and republished them in 1906 under the title Peter Pan in Kensington Gardens, with the addition of illustrations by Arthur Rackham.

The character's best-known adventure debuted on 27 December 1904, in the stage play Peter Pan, or The Boy Who Wouldn't Grow Up. This story was adapted and expanded somewhat as a novel, published in 1911 as Peter and Wendy, later as Peter Pan and Wendy, and still later as simply Peter Pan.
