"Switch" is a song recorded by Australian rapper Iggy Azalea featuring Brazilian singer Anitta, from her upcoming second studio album, Digital Distortion. It was released on 19 May 2017, by Def Jam as the third single from the album. "Switch" was written by Azalea with Maurice "Verse" Simmonds. It was produced by The Family and Eric Weaver. "Switch" is a pop song, with a tropical vibe and Latin flavor, having in its instrumentation bass, plucky strings, bongos, and hand claps.

Azalea's sophomore studio album, Digital Distortion, was initially set to be released on 24 June 2016, with its lead-single "Team", being released in March 2016. However, the album was postponed several times in 2016, with Azalea initially addressing the delay due to her stint as a judge on the eighth season of The X Factor Australia, and later adding that she also delayed the album to include a collaboration with Russian-German DJ Zedd. Eventually, the album was postponed to 2017, since Azelea claimed she experienced both personal and creative changes. In March 2017, she released the song "Mo Bounce" as a single, however the song was a commercial lackluster.

Quickly afterwards, Azalea teased a snippet of a song in an Instagram video with the caption: "IGGY X ANITTA" in early April, indicating that she was collaborating with Brazilian recording artist Anitta. Later in the same month, they were seen together in the studio to finish the track. Eventually, Azalea revealed that the track was called "Switch" by posting its cover art on 2 May 2017. In the cover art, she is "staring into the camera while wearing a one-piece maroon bathing suit," as described by Billboard's Gil Kaufman. It was released digitally on 19 May 2017 by Def Jam Recordings, and was sent to both contemporary hit radio and rhythmic contemporary radio on 23 May 2017.
