The Great Milenko is the fourth studio album by American hip hop group Insane Clown Posse, released on June 24, 1997, by Hollywood Records in association with Psychopathic Records. As the fourth Joker's Card in the group's Dark Carnival mythology, the album's lyrics focus on the titular Great Milenko, who is a necromancer.

The album was recorded and initially released by the Disney-owned record label Hollywood Records. The album was taken off shelves by Hollywood hours after its release, in response to criticism from the Southern Baptist Church of decisions that the church believed did not reflect Disney's family-friendly image, although Disney claimed that the album was released due to an oversight by its review board. After Hollywood terminated the group's contract, Insane Clown Posse signed a new contract with Island Records (whose parent at the time, PolyGram, distributed Hollywood releases in North America), which agreed to release the album as it was originally intended. Island then re-released the album on August 12, 1997.

The music of The Great Milenko features a rap metal sound and features guest appearances by popular rock stars Alice Cooper, Steve Jones and Slash. Although the album was poorly received by critics, it debuted at number 63 on the Billboard charts, and was later certified platinum by the Recording Industry Association of America (RIAA).
