Night in the Ruts is the sixth studio album by American hard rock band Aerosmith.

Joe Perry left the band midway through the recording of the album. The album was not produced by Jack Douglas who had produced Aerosmith's previous four albums. Instead, Columbia Records brought in Gary Lyons as a producer. About halfway through the recording of the album, the record label and management set Aerosmith out on another tour without extra time to finish the album, which pushed the album to being released later in the year. Joe Perry left the band mid-way through the tour, after a violent feud involving the band members and their wives. Prior to his departure, Perry had completed guitar parts for "No Surprize", "Chiquita", "Cheesecake", "Bone to Bone (Coney Island Whitefish Boy)", and "Three Mile Smile". The guitar parts for the remaining songs were recorded by Brad Whitford, Richie Supa, Neil Thompson, and Jimmy Crespo (who later became Perry's official replacement from 1979 to 1984).

Despite some critical acclaim and early success, the album quickly fell down the charts. The album has since achieved platinum status. Promo videos for "No Surprize" and "Chiquita" were filmed (featuring Perry's replacement Jimmy Crespo); however, these videos received little television airplay.

The title is an intentional spoonerism of the phrase "right in the nuts", which was subsequently the title of the tour.
