Matt Stone is an American writer, producer, actor, voice artist, musician, and animator best known as co‑creator (with Trey Parker) of the long‑running animated series South Park and co‑creator of the Broadway musical The Book of Mormon. He was born May 26, 1971, in Houston, Texas, and raised in Littleton, Colorado; he met Parker at the University of Colorado at Boulder, where they collaborated on early projects that led to their professional partnership[1][2]. Stone and Parker launched South Park on Comedy Central in 1997; the series—noted for its crude animation, satirical edge, and willingness to lampoon religion, politics, and pop culture—made both creators the primary writers, directors and frequent voice performers for the show’s principal characters[1][2][3]. The duo expanded their work to feature films and other projects, including South Park: Bigger, Longer & Uncut (1999), Team America: World Police (2004), and the independent films Cannibal! The Musical and Orgazmo[2][3][5]. In theater, Stone and Parker collaborated with composer-lyricist Robert Lopez to create The Book of Mormon (2011), a satirical stage musical that won multiple Tony Awards, including Best Musical, and earned a Grammy for its original cast recording[1][2]. Stone has also been involved in producing South Park spinoffs, documentaries, and various television and film projects across his career[3][4]. Key achievements include creating one of television’s most influential and controversial animated comedies and co‑writing a Tony‑winning Broadway musical[1][2]. Stone continues to be credited as an executive producer, writer, and voice actor on South Park and remains an active figure in entertainment production[3][5]. Public biographical profiles list him as based in the Los Angeles area and note ongoing involvement in film and television projects[3][5].
