"All I Can Think About Is You" is a song by British rock band Coldplay from their EP Kaleidoscope (2017). It was released ahead of the EP on 15 June 2017, following "Hypnotised" and preceding "Aliens". The track was composed by all four members of the band and produced by Dan Green along with Rik Simpson. An animated lyric video directed by I Saw John First came out on the same day.
Colin Stutz of Billboard magazine wrote: "The understated song rides on a rolling bassline and steady rhythm with light guitar licks that mesmerize as they build to a soaring climax." He also noted that the lyric video is "equally trippy" as the track. Anna Gaca of Spin magazine called the song "unusually shoegaze-y". Andrew Pollard of Redbrick said that the song "feels like a celebration of their [Coldplay] distinct sound and musical past rather than a lazy rehash". Ben Kaye of Consequence of Sound said that the song has "a psychedelic dream of jammy guitars and gentle percussion".
