Matthew Richard Stone (born May 26, 1971) is an American actor, animator, writer, producer, and composer. He is known for co-creating South Park (1997–present) and co-developing The Book of Mormon (2011) with his creative partner Trey Parker. Stone was interested in film and music as a child and at high school, and attended the University of Colorado, Boulder, where he met Parker. The two collaborated on various short films, and starred in the feature-length musical Cannibal! The Musical (1993).

Stone and Parker moved to Los Angeles and wrote their second film, Orgazmo (1997). Before the premiere of the film, South Park premiered on Comedy Central in August 1997. The duo possess full creative control of the show, and have produced music and video games based on it. A film based on the series, South Park: Bigger, Longer & Uncut (1999), received good reviews from both critics and fans. Stone went on to write, produce, and star in the satirical action film Team America: World Police (2004), and, after several years of development, The Book of Mormon premiered on Broadway to good reviews. In 2013, Stone and Parker established their own production studio, Important Studios.

Stone has been the recipient of various awards over the course of his career, including five Primetime Emmy Awards for his work on South Park, as well as three Tony Awards and one Grammy Award for The Book of Mormon.

In 2021, Stone and Parker signed a $900 million deal with ViacomCBS to make six additional seasons of South Park and 14 movies in the South Park universe for streaming.
