A juggalo (feminine juggalette, or juggala in Spanish) is a fan of the group Insane Clown Posse or any other Psychopathic Records hip hop group.

Juggalos have developed their own idioms, slang, and characteristics. Welcome to The Gathering of the Juggalos, alternatively known as just "The Gathering"

The term originated during a 1994 live performance by Insane Clown Posse. During the song "The Juggla," Violent J addressed the audience as Juggalos, and the positive response resulted in Violent J and Shaggy 2 Dope using the word thereafter to refer to themselves and their fans.

According to Shaggy 2 Dope, "Juggalos come from all walks of life – from poverty, from rich, from all religions, all colors. It doesn't matter if you're born with a silver spoon in your mouth or a crack rock in your mouth."

Common characteristics of identifying a member of the Juggalo subculture are as follows: Drinking and spraying the inexpensive soft drink Faygo. Listening to horrorcore and other types of underground rap music. Wearing face paint. Wearing HatchetGear. Having the Hatchet man logo applied on personal effects and, worn as jewelry. Making and responding to "whoop, whoop" calls. Expressing a (generally) tongue-in-cheek obsession with murder. Juggalos view the lyrics of Psychopathic Records artists, which are often violent in nature, as a catharsis for aggression.

The Insane Clown Posse filed a lawsuit against the FBI about the gang-listing. In December 2012, ICP agreed to withdraw their involvement as plaintiffs.
