What Broadway musical did South Park creators Trey Parker and Matt Stone co-create?

The Broadway musical co-created by South Park creators Trey Parker and Matt Stone is The Book of Mormon. They developed it with Robert Lopez, the composer and co-creator of Avenue Q, making the show a collaboration among three major figures in modern musical comedy.

The musical follows two young missionaries of The Church of Jesus Christ of Latter-day Saints who are sent to a village in Uganda. Its comedy satirizes missionary culture, religious storytelling, cultural assumptions, and the tension between literal belief and metaphorical meaning, while also giving its characters sincere emotional stakes.

Parker, Stone, and Lopez began developing the project in the mid-2000s. They wrote early songs and shaped the story around their shared interest in Mormon history and Joseph Smith. Workshops followed, and the show eventually premiered on Broadway at the Eugene O’Neill Theatre on March 24, 2011.

The Book of Mormon won major awards, including nine Tony Awards. Its creators are sometimes confused with the writers of Avenue Q because Lopez co-created that musical too, but Avenue Q is not the South Park duo’s Broadway show. Hamilton and Spamalot were created by different teams.
