What is the name of the South Park boys' school?

The South Park boys attend South Park Elementary. It is the fictional public elementary school in the Colorado town of South Park and serves as the main school setting for much of the series.

Stan Marsh, Kyle Broflovski, Eric Cartman, and Kenny McCormick regularly meet there, attend classes, interact with teachers, and become involved in the show’s increasingly bizarre conflicts. Mr. Garrison is one of the most recognizable teachers associated with the school, while Principal Victoria and later Principal PC Principal also play important roles.

The boys were initially depicted as third-graders during the show’s first 58 episodes. After that, they moved to fourth grade, although the series uses a famously elastic timeline in which the characters remain roughly the same age for many years.

The name can be confused with real schools called South Park Elementary School, including schools in British Columbia and Kansas. In trivia about the animated series, however, the canonical answer is the fictional South Park Elementary, not Colorado Elementary or another invented variation.
