James Bigglesworth, nicknamed "Biggles", is a fictional pilot and adventurer, the title character and hero of the Biggles series of adventure books, written for young readers by W. E. Johns (1893–1968). Biggles made his first appearance in the story The White Fokker, published in the first issue of Popular Flying magazine and again as part of the first collection of Biggles stories, The Camels Are Coming. Johns continued to write "Biggles books" until his death in 1968. The series eventually included nearly a hundred volumes – novels as well as short story collections – most of the latter with a common setting and time.

William Earl Johns was an English First World War pilot, and writer of adventure stories, usually written under the pen name Capt. W. E. Johns: best known for creating the fictional air-adventurer Biggles.
