"Crack Addict" is a song by Limp Bizkit written and recorded in 2003.

The song was written while the group was still without a guitarist, so Fred Durst, and Brian Welch of Korn wrote the guitar for the song.

The song was named the official theme song for World Wrestling Entertainment's WrestleMania XIX Pay-Per-View. The song was performed live by Limp Bizkit at WrestleMania XIX. Limp Bizkit also performed "Rollin' (Air Raid Vehicle)" during The Undertaker's match. The song was never released on a CD by the band but it can be heard on the WrestleMania XIX DVD.

The song was also included in the Fight Club video game. But, as of October, 2007 it was released though their Myspace.
