Peter Llewelyn Davies, English soldier and publisher (d. 1960)
Peter Llewelyn Davies MC (25 February 1897 – 5 April 1960) was the middle of five sons of Arthur and Sylvia Llewelyn Davies, one of the Llewelyn Davies boys befriended and later informally adopted by J. M. Barrie. Barrie publicly identified him as the source of the name for the title character in his 1904 play Peter Pan, or The Boy Who Wouldn't Grow Up. This public identification as "the original Peter Pan" plagued Davies throughout his life, which ended in suicide.

He was awarded the Military Cross after serving as an officer in World War I, and in 1926 founded the publishing house Peter Davies Ltd.

He was the first cousin of the English writer Daphne du Maurier.
