Leopold "Butters" Stotch is a fiction character in the animated television series South Park. He is voiced by series co-creator Matt Stone and loosely based on co-producer Eric Stough. He is a fourth-grade student who commonly has extraordinary experiences not typical of conventional small-town life in his fictional hometown of South Park, Colorado. Butters is cheerful, naive, optimistic, and more passive relative to the show's other child characters, and can become increasingly anxious, especially when faced with the likelihood of his parents' punishments.

Butters debuted as a background character when South Park first aired on August 13, 1997, and his role gradually increased as the series progressed, beginning with the show's sixth season (2002). The scenes involving his exploitation at the hands of antagonist Eric Cartman are ones that the show's creators have most enjoyed writing, and have become one of the show's more recent recurring staples.

Butters attends South Park Elementary as part of Mr. Garrison's 4th grade class. During the show's first 58 episodes (1997 through the season four episode "4th Grade" in 2000), Butters and the other main child characters were in the third grade. He lives in South Park as the only child of Stephen and Linda Stotch, by whom he perpetually faces the looming prospect of getting grounded. Everything seems to go wrong for Butters as bad luck and punishment seem to follow him. For instance, the end of many episodes end with him being grounded. It is revealed in the Episode Awesom-O that his birthday is September 11. When the character of Kenny McCormick was temporarily written off the show near the end of the fifth season (2001), Stan Marsh, Kyle Broflovski, and Cartman allow Butters into their group as the "fourth friend", a role he continued to fill until midway through season six. During this period, the boys would often take advantage of Butters's mild temperament by making him a stooge in their own personal schemes. The three eventually ousted him in favor of Tweek Tweak.

As a result, Butters vengefully adopted the mean alter ego of Professor Chaos. Intending to be a supervillain, Professor Chaos wears a green cape, and a helmet and gauntlets constructed out of cardboard and aluminum foil. Butters as Professor Chaos received much focus during the back-to-back episodes "Professor Chaos" and "Simpsons Already Did It", where he took on his younger friend Dougie as his sidekick General Disarray and ultimately failed at their several ill-prepared attempts to create "worldwide chaos". Professor Chaos has occasionally made a few appearances since, appearing to be a known supervillain to South Park's police force. Despite being displaced from both his role as the "fourth friend" and from the eventual return of Kenny, Butters has continued to be a major character in recent seasons. Still the social outcast, he has nevertheless been seen spending considerable amount of time with the other children, and continues to be a frequent source of help to Cartman, while also being the main victim of Cartman's pranks and manipulation.

Butters Stotch has not been a contender in any CBUB matches.
