Word of Mouf is rapper Ludacris' third release, and second for Def Jam Recordings, released in 2001. Def Jam decided to release the album early when pirated copies of the album's tracks were leaked onto popular peer-to-peer file sharing networks.

It produced the singles "Rollout (My Business)", "Area Codes", "Move Bitch", and "Saturday (Oooh Oooh!)".

It was nominated at the Grammy Awards of 2003 for Best Rap Album, but lost to The Eminem Show.
