The Flintstones: On the Rocks is an animated TV movie based on the popular animated franchise The Flintstones, which aired in 2001 on Cartoon Network. The film features the voices of Jeff Bergman as Fred, Tress MacNeille as Wilma, with additional voices by Bergman, MacNelle, Frank Welker (Dino), Zelda Rubinstein, Kevin Richardson (Barney), Grey DeLisle (Betty), Tom Kenny, and Jeff Glen Bennett.

In format, the movie was intended to emulate the original prime time seasons of the series, which were distinctly more mature and aimed at older audiences, and therefore chose to focus more on the relationships between the original core cast of Fred, Barney, Wilma, and Betty. It was animated by Chris Savino and David Smith.
