Fat Albert is a 2004 American live-action/animated comedy film based on the 1972 Filmation animated television series Fat Albert and the Cosby Kids created by Bill Cosby. Kenan Thompson stars as the title character. Fat Albert transforms the cartoon characters into three-dimensional humans, who have to come to grips with the differences that exist between their world and the real world.

The film acts as a continuation of the series; Fat Albert and the gang leave their 1972-1985 cartoon world, and enter the 2000s real world to help a teenage girl, Doris Robertson (Kyla Pratt), deal with the challenges of being unpopular. The film was released on December 25, 2004, to generally negative reviews and grossed $48 million against a $45 million budget.
