The ArchAndroid is the debut studio album by American singer and songwriter Janelle Monáe, released on May 18, 2010, by Wondaland Arts Society, Bad Boy Records, and Atlantic Records. Production for the album took place at Wondaland Studios in Atlanta and was primarily handled by Monáe, Nate "Rocket" Wonder, and Chuck Lightning, with only one song without production by Monáe. She also collaborated for certain songs with Saul Williams, Big Boi, of Montreal, and Deep Cotton.

The album is composed of the second and third parts to Monáe's Metropolis concept album series. Incorporating conceptual elements of Afrofuturism and science fiction, The ArchAndroid continues the series' fictional tale of a messianic android and features lyrical themes of love, identity, and self-realization. Critical commentaries have compared the album to the works of David Bowie, Outkast, Prince and Michael Jackson.

The ArchAndroid debuted at number 17 on the US Billboard 200, selling 21,000 copies in its first week, while charting modestly in several other countries. Monáe promoted the album with the release of two singles – "Tightrope" and "Cold War" – and concert tours in 2010 and 2011. A widespread critical success, The ArchAndroid received praise for its thematic concepts and Monáe's eclectic musical range. It later ranked among 2010's best albums in many critics' lists and earned the singer a Grammy Award nomination for Best Contemporary R&B Album.
