Peter Pan is a fictional character created by British novelist and playwright J. M. Barrie. First appearing in a subplot of the novel The Little White Bird (1902), the character's role was expanded for the West End stage play Peter Pan; or, the Boy Who Wouldn't Grow Up (1904), which was novelised as Peter and Wendy (1911). A free-spirited and mischievous young boy who can fly and never grows up, Peter Pan spends his never-ending childhood having adventures on the mythical island of Neverland as the leader of the Lost Boys, interacting with fairies, pirates, mermaids, Amerindians, and occasionally ordinary children from the world outside Neverland. Peter Pan has become a cultural icon symbolising youthful innocence and escapism.

Peter Pan is a frequent protagonist in Crossover Oz fiction, second only to Alice of Wonderland in the number of times the character has met Oz-related characters.
