Chaosphere is the third album by Swedish metal band Meshuggah. It was released on November 10, 1998, by Nuclear Blast. Chaosphere's sound is largely a combination of the thrash style of the band's previous releases and the technicality that they would further explore on subsequent albums. A video was made for "New Millennium Cyanide Christ".
The Japanese version of the album contains a bonus song, titled "Unanything", as track 9. This song was also included on the promotional card-sleeve CD as track 6. At the end of the track 8, all the songs from the album are played at once.
