Which South Park character's full name is Leopold Stotch?

Leopold Stotch is the full name of Butters, the optimistic, anxious fourth-grader from South Park. He is usually called simply “Butters,” a nickname that became his defining identity in the series.

Butters was introduced as a minor classmate but gradually became one of South Park’s most prominent characters. His sheltered upbringing, strict parents, and relentlessly cheerful personality make him an easy target for Cartman and the other boys. Despite frequent mistreatment, Butters often remains unusually trusting and polite.

A common mix-up is confusing Butters with other members of the boys’ circle. Jimmy Valmer is the aspiring comedian, Tweek Tweak is the highly nervous coffee-loving student, and Token Black is a wealthy classmate. None of those characters is Leopold Stotch. Butters’ surname is also sometimes remembered incorrectly because “Stotch” is more commonly heard than his first name.
