John Kendrick Bangs (1862-1922) was an American humorist chiefly remembered for two things:
- The creation of the genre of "Bangsian Fantasy", in which various familiar characters from different periods of history meet in an afterlife scenario, in his book A Houseboat on the Styx and sequels. The series was an obvious influence on Philip José Farmer's Riverworld novels.
- copious affectionate Sherlock Holmes parodies.
He was a personal friend of Arthur Conan Doyle, and (as Bangs revealed in an 1899 New York Times interview) visited him at Undershaw in 1898.
