Insane Clown Posse is an American hip hop duo from Detroit, Michigan. The group is composed of Joseph Bruce and Joseph Utsler, who perform under the respective personas of the wicked clowns Violent J and Shaggy 2 Dope. Insane Clown Posse performs a style of hardcore hip hop known as horrorcore and is known for its elaborate live performances. The duo has earned two platinum and three gold albums. According to Nielsen SoundScan, the entire catalog of the group has sold 6.5 million units in the United States and Canada as of April 2007.

Originally known as Inner City Posse, the group introduced supernatural- and horror-themed lyrics as a means of distinguishing itself stylistically. The duo founded the independent record label Psychopathic Records with Alex Abbiss as manager, and produced and starred in the feature films Big Money Hustlas and Big Money Rustlas. They formed their own professional wrestling federation, Juggalo Championship Wrestling, and later collaborated with many famous hip hop and rock musicians.

The themes of Insane Clown Posse and other acts on Psychopathic Records center on the mythology of the Dark Carnival, which the duo claim is a spiritual force that has revealed a series of stories known as Joker's Cards. These stories each offer a specific lesson designed to change the "evil ways" of listeners before "the end consumes us all." Insane Clown Posse has a dedicated following, often referred to by the group as Juggalos and Juggalettes.
