I Am Weasel is an American animated television series created by David Feiss for Cartoon Network. It is the fourth of the network's Cartoon Cartoons and the final to be produced solely by Hanna-Barbera. The series centers on I.M. Weasel (voiced by Michael Dorn), a smart, noble and successful weasel, I.R. Baboon (voiced by Charlie Adler), an unintelligent and rude baboon who is envious of Weasel and acts as both his rival and friend, and the mischievous Red Guy (also voiced by Adler), returns from Cow and Chicken to antagonize the duo.

I Am Weasel originally aired as a segment of Cow and Chicken from 1997 to 1999, often airing as the third of three segments in an episode, and eventually became a spin off into its own series. A fifth season with 27 new episodes aired from June 10, 1999, to 2000 and joined the original 52 which were previously part of Cow and Chicken. The entire series includes 79 episodes overall.
