The Dirt is a 2019 American biographical comedy-drama film directed by Jeff Tremaine from a screenplay by Rich Wilkes and Amanda Adelson, about heavy metal/glam metal band Mötley Crüe. The film stars Douglas Booth, Colson Baker, Daniel Webber and Iwan Rheon.

Talks of a Mötley Crüe biopic began as early as 2006, when Paramount Pictures and MTV Films purchased the rights to the book The Dirt: Confessions of the World's Most Notorious Rock Band by the band and Neil Strauss; however, the project then languished in development hell for over a decade, going through numerous directors and cast members before Netflix purchased the rights in March 2017. Filming began around New Orleans in February 2018.

The Dirt was released digitally on Netflix on March 22, 2019. It received generally negative reviews from critics, who said the film would please fans but that it hesitated "in handling the more troubling aspects of the band's history."
