"Mr. Roboto" is a song by American rock band Styx, released as the lead single from their eleventh studio album, Kilroy Was Here (1983).

Stan Winston, who would become well-known through his work on The Terminator, Aliens, Iron Man, and Jurassic Park, designed the Roboto costume and mask, which are displayed prominently on the cover of the album Kilroy Was Here.

The track was released as the first single from the album at the last minute instead of "Don't Let It End" and turned out to be the band's last Top 5 US hit for eight years.

[10] In addition, many have cited this song and the album as potentially having alienated older fans, some calling it "jumping the shark" for the band.

"[13] Billboard called it "a mesh of bouncy melody, electronically distorted vocals and a refrain in Japanese," saying that "the group bemoans the plight of 'modern man' oppressed by technology".

[14] The song's video, directed by Brian Gibson, depicts Jonathan Chance (played by guitarist Tommy Shaw) walking into the Rock Museum to meet Kilroy, and a robot approaches.

[15] Shortly thereafter, the robots transform into the members of Styx, including a clean-shaven Dennis DeYoung (he shaved his trademark moustache off at the conclusion of the Paradise Theater tour in 1982).
