Billy Bounce was a comic strip published erratically by noted illustrator W.W. Denslow (1901–1902; 1906) and later C.W. Kahles (1902–1905) between 1901 and 1906. The strip centers on the actions of the title character, a ball-shaped boy who is capable either of bouncing long distances or actual flight. It is noted as one of the earliest comic strips in which the protagonist has superpowers.
Like its contemporary, Little Nemo in Slumberland, which came shortly after Billy Bounce, the strip dealt with otherworldly situations and often had recurring characters, including the King of the Pollywogs, Fuzzy White and Prunes the Pieman.
In September 1906, Denslow published a single novel based on Billy's adventures, titled simply 'Billy Bounce'. Denslow provided illustrations and the text was written by Dudley A. Bragdon. It was published by G.W. Dillingham Co. in New York.
