Arthur Llewelyn Davies was an English barrister of Welsh origin, but is best known as the father of the boys who were the inspiration for the stories of Peter Pan by J. M. Barrie.

The Davies boys were the inspiration for the stories of Peter Pan by J. M. Barrie, in which several of the characters were named after them. They were the sons of Sylvia (1866–1910) and Arthur Llewelyn Davies (1863–1907). Their mother was a daughter of French-born cartoonist and writer George du Maurier and sister of actor Gerald du Maurier, whose daughter was author Daphne du Maurier. Their father was a son of preacher John Llewelyn Davies, and brother of suffragist Margaret Llewelyn Davies.
