Eric Theodore Cartman, usually referred to as just Cartman, is the main character of the South Park franchise. He is the main character of South Park, and one of the two main characters (alongside Kyle Broflovski) of South Park: Bigger, Longer & Uncut.

He is often thought to be the show's main protagonist because he used to have more screen time than Stan. But that's not true because Stan always been more important than him so that makes Stan the true show's main protagonist.
