List of episodes

The fourth season of South Park, an American animated television series created by Trey Parker and Matt Stone, began airing on April 5, 2000. The fourth season concluded after airing 17 episodes on December 20, 2000.

The first four episodes in this season has the year 2000 at the end of their episode titles. As explained in the FAQ section on the official website: "When the year 2000 was coming up, everyone and their brother had '2000' in the titles of their products and TV shows. America was obsessed with 2000, so Trey Parker put '2000' in the titles to make fun of the ubiquity of the phrase."^[1][2]

This is the first season not to feature Mary Kay Bergman as a series regular, who provided many of the female voices on the show (Bergman committed suicide on November 11, 1999). It also marks the only whole season to be animated with their old software PowerAnimator before switching to Maya without her. Eliza Schneider and Mona Marshall replaced Mary Kay Bergman in season four after her death.^[3][4]
