R. Crumb (born August 30, 1943, in Philadelphia, Pennsylvania) is a U.S. artist and illustrator recognised for the distinctive style of his drawings and his critical, satirical, subversive view of the American mainstream. He currently lives in France.

Crumb was a founder of the underground comix movement and is regarded as its most prominent figure. In the pages of the many comix and counterculture publications, Crumb created characters that became counterculture icons. The best known of these, are Mr. Natural and Fritz the Cat. Crumb's work was suddenly in great demand, and Crumb himself became an anti-establishment icon, a figure that genuinely resisted "selling out."
