Peter Pan in Kensington Gardens is a novel by J. M. Barrie, illustrated by Arthur Rackham, and published by Hodder & Stoughton in late November or early December 1906; it is one of four major literary works by Barrie featuring the widely known literary character he created, Peter Pan. Most of the text originally appeared as chapters 13–18 of Barrie's 1902 novel The Little White Bird.

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.
