James St. James (born James Clark[1], August 1, 1966) was a Club Kid of the Manhattan club scene in the late 1980s/early 1990s and the author of Disco Bloodbath (now published under the title Party Monster). He was notorious for a lifestyle of excess that included heavy drug use, partying, and bizarre costumes.

Disco Bloodbath: A Fabulous but True Tale of Murder in Clubland is a 1999 memoir written by James St. James about his life as a Manhattan celebutante and club kid. The book specifically chronicles his friend Michael Alig's rise to fame and his subsequent murder of fellow club kid and drug dealer Angel Melendez. St. James was Alig's mentor in the scene, giving him a very personal view into the story, which comes through in the book. The memoir was later renamed Party Monster after the motion picture of that name was made based on the book starring Macaulay Culkin, Seth Green, Chloë Sevigny and Marilyn Manson.
