Peter Pan; or, the Boy Who Wouldn't Grow Up, often known simply as Peter Pan, is a work by J. M. Barrie, in the form of a 1904 play and a 1911 novel titled Peter and Wendy, often extended in Peter Pan and Wendy. Both versions tell the story of Peter Pan, a mischievous little boy who can fly, and has many adventures on the island of Neverland that is inhabited by mermaids, fairies, Native Americans, and pirates. The Peter Pan stories also involve the characters Wendy Darling and her two brothers John and Michael, Peter's fairy Tinker Bell, the Lost Boys, and the pirate Captain Hook. The play and novel were inspired by Barrie's friendship with the Llewelyn Davies family.

Sir James Matthew Barrie, 1st Baronet, was a Scottish novelist and playwright, best remembered as the creator of Peter Pan. He was born and educated in Scotland and then moved to London, where he wrote several successful novels and plays. There he met the Llewelyn Davies boys, who inspired him to write about a baby boy who has magical adventures in Kensington Gardens, then to write Peter Pan, or The Boy Who Wouldn't Grow Up, a 1904 West End "fairy play" about an ageless boy and an ordinary girl named Wendy who have adventures in the fantasy setting of Neverland.
