Bad Witch is the ninth studio album by the American industrial rock band Nine Inch Nails, released by The Null Corporation and Capitol Records on June 22, 2018. It is the last of a trilogy of releases, following their two previous EPs Not the Actual Events (2016) and Add Violence (2017). As with the previous releases in the trilogy, it was produced by frontman Trent Reznor and Atticus Ross, making it the band's first studio album since 2007's Year Zero to not be co-produced by the long-time collaborator Alan Moulder, who is credited with mixing the album.

Nine Inch Nails, commonly abbreviated as NIN, stylized as NIN, is an American industrial rock band formed in Cleveland in 1988. Singer, songwriter, multi-instrumentalist, and producer Trent Reznor was the only permanent member of the band until his frequent collaborator, Atticus Ross, joined in 2016. The band's debut album, Pretty Hate Machine (1989), was released via TVT Records. After disagreeing with TVT about how to promote the album, the band signed with Interscope Records and released the EP Broken (1992). The following albums, The Downward Spiral (1994) and The Fragile (1999), were released to critical acclaim and commercial success.
