Koko the Clown is an animated character created by Max Fleischer's cartoon studios. He was the first star character of this New York City based animation studio, from the silent film era, staring in the Out of the Inkwell series of cartoons in the 1920s. The Fleischer Studios were pioneers in experimenting with combining animation and live action characters in a way that prefigured Who Framed Roger Rabbit.

Koko later appeared with Betty Boop in the 1930s. After Fleischer was bought out by Paramount Studios, Koko continued to be revived periodically for made for television cartoons into the early 1960s.
