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.
The story of this book is set in Kensington Gardens, one of the London Royal Parks, mostly after "Lock-Out Time", described by Barrie as the time at the end of the day when the park gates are closed to the public. After this time the fairies, and other magical inhabitants of the park, can move about more freely than during the daylight, when they must hide from ordinary people.
