Matt Stone (Kyle Broflovski, Kenny McCormick, etc.)

As a showrunner of South ParkMatt Stone is also one of the main voice actors bringing the animated characters to life. He portrays major players like Kyle Broflovski, Kenny McCormick (while muffled), and Butter Stotch, plus variations of their parents and a slew of other South Park residents.

While South Park and its movie installments have made up the bulk of Stone’s work, he also co-created the Broadway sensation The Book of Mormonhelmed the raunchy sports comedy BASEketball (1998), and wrote and starred in Team America: World Police (2004). In addition to five Emmy wins for South Park, he netted a Grammy and three Tonys for The Book of Mormon.

Stone has been married to Comedy Central executive Angela Howard since 2008. They share two children.

Trey Parker (Stan Marsh, Eric Cartman, etc.)

Carrying the rest of the core friend group, Parker voices would-be hero Stan Marsh and the potty-mouthed Eric Cartman, along with Jimmy, Stan’s father Randy, Mr. Garrison, and many more characters across the show’s run.

Working with Stone, Parker was the second brain behind The Book of Mormon and their subsequent Grammy and Tony wins. His filmography also mirrors Stone’s with collaborations on projects like BASEketball and Team America: World Policeas well as many South Park spinoff movies.

Parker was married to Emma Sugiyama from 2006 to 2008. He has one daughter with Boogie Tillmon, whom he married in 2014, and a stepson from Tillmon’s previous relationship. They divorced in 2019.

Mona Marshall (Sheila Broflovski, Linda Stotch, etc.)

Mona Marshall joined South Park in 1999 after the death of original cast member Mary Kay Bergmanwho voiced Kyle’s mom Sheila Broflovski, Butters’ mother Linda Stotch, and various celebrity bit parts like Hillary Clinton.

A stage-trained actress, Marshall has done voice acting in animated shows like Fraggle Rock: The Animated Series. She’s also found a particular niche in anime, including hack//Sign (2003), Digimon Adventure (1999–2001), NARUTO (2005–2009), Doraemon (2014), and Uzumaki (2024).

Marshall also works as a voice and stage acting coach.

April Stewart (Sharon Marsh, Liane Cartman, Wendy Testaburger, etc.)

Isaac Hayes (Chef)

Isaac Hayes’ buttery smooth voice wasn’t the only thing that set him apart in the South Park universe. He also notably only played one role: a highly inappropriate school cook known only as Chef.

Before Hayes died in 2008, he was an American musical icon as a singer, songwriter, producer, and all-around creative force. Hayes was a major player in the Memphis label Stax Records and co-wrote the Sam & Dave song “Soul Man.”

In addition to three Grammy Awards and an induction into the Rock and Roll Hall of Fame, his work as a film composer earned him an Oscar for Best Song for the film Shaft (1971). As for acting, he appeared in Escape From New York (1981) and starred as Gandolf “Gandy” Fitch in The Rockford Files (1974–1980).

Hayes, a Scientologist, had a controversial exit from South Park in 2006 after their Scientology-critical episode “Trapped in the Closet” aired. Speaking to The Hollywood Reporter for the show’s 20th anniversary, his son Isaac Hayes III explained, “At the time, everybody around my father was involved in Scientology — his assistants, the core group of people. So someone quit South Park on Isaac Hayes’ behalf. We don’t know who.”

His son clarified that at that point, Hayes was unable to speak after suffering a stroke in 2006. He also noted that “(South Park) really gave (Hayes) a huge second act as an artist, and he was very thankful and proud of that.”

Adrien Beard (Token/Tolkien Black, etc.)

In a show known for pushing social and cultural buttons, one character especially captures South Park’s commentary on race relations in the U.S.: Token Black, later known as Tolkien Black, voiced by South Park storyboard artist, producer, and art director Adrien Beard.

Beard’s other roles include Token Williams, Mr. Williams, Steve Black, Mr. Black, and Squirrely the Squirrel, all of whom highlight problematic racial stereotypes and caricatures in South Park’s signature style.

Beard’s work has solely focused on South Park and its variety of offshoots, winning him three Emmys Awards and two additional nominations.

Eliza Schneider (Liane Cartman, Sharon Marsh, etc.)

Eliza Schneider joined the South Park cast along with Mona Marshall after Mary Kay Bergman died in 1999. She remained a regular cast member until 2003, voicing folks like Liane Cartman, Sharon and Shelley Marsh, Principal Victoria, Mayor McDaniels, Wendy Testaburger, Carol McCormick, and Ms. Crabtree, among others. April Stewart was hired to replace her in 2004.

Schneider’s voice appears on TV shows like The Zeta Project (2002), Invader Zim (2003), Squirrel Boy (2007), Popzilla (2009), Batman: The Brave and the Bold (2011), Sanjay and Craig (2015–2016), and Rise of the Teenage Mutant Ninja Turtles (2018). She was also part of Honey Pig, an all-women country music group.

Schneider has a son with her partner, Roger Ray, and works as a violin instructor alongside her voice acting career.

Jennifer Howell (Bebe Stevens)

Another voice from behind the scenes is supervising producer Jennifer Howell as Bebe Stevens, who is often a love interest in the series.

As Howell continued voicing Bebe, she also became the executive vice president of Stone and Parker’s Important Films production company in 2006 before transitioning to senior vice president of 20th Century Fox Television’s animation department in 2008. According to LinkedIn, she is currently the chief creative officer of Deep VooDoo, an AI entertainment startup founded by Stone and Parker.

Jessica Makinson (Strong Woman, Gigi Hadid)

Unlike The Simpsons, South Park doesn’t rely on actual celebrity cameos for special episodes. Instead, voice actor Jessica Makinson tackles many female celebs — either accurately or badly on purpose (this is South Parkafter all). Beyond voicing pop culture icons like Gigi Hadid and Paris HiltonMakinson also portrays recurring characters like Strong Woman, Henrietta Biggle, and more.

She was no stranger to working with Parker and Stone, appearing in their political sitcom That’s My Bush (2001). Makinson has also acted in sketches for Jimmy Kimmel Live, The Late Late Show With Craig Fergusonand Showtime’s The Underground. Her other on-screen work includes roles in Comedy Central’s Trigger Happy TV (2003), The Joe Schmo Show (2004) on Spike, and Nickelodeon’s iCarly (2008).
