Bosko is an animated cartoon character created by animators Hugh Harman and Rudolf Ising. Bosko was the first recurring character in Leon Schlesinger's cartoon series and was the star of thirty-nine Looney Tunes shorts released by Warner Bros. He was voiced by Carman Maxwell, Johnny Murray, and Billie "Buckwheat" Thomas during the 1920s and 1930s and once by Don Messick during the 1990s.

Leon Schlesinger was an American film producer who founded Leon Schlesinger Productions, which later became the Warner Bros. Cartoons studio, during the Golden Age of American animation. He was a distant relative of the Warner Brothers. As head of his own studio, Schlesinger served as the producer of Warner's Looney Tunes and Merrie Melodies cartoons from 1930, when Schlesinger assumed production from his subcontractors, Harman and Ising, to 1944, when Warner acquired the studio.
