Jupiter is the second full-length album by alternative metal band Cave In, released in summer 2000. It marked a change in the band's style, as this album saw the band move away from its previous hardcore sound by starting to experiment with more elements of space rock and psychedelic rock. "Big Riff" was the only song on the album to contain screamed vocals.

There are four different tints to the album cover: green (initial release), magenta (second press), blue (third press), and yellow (fourth press).

In December 2009, Decibel magazine named Jupiter the second-best metal album of the decade. In 2020, it was named one of the 20 best metal albums of 2000 by Metal Hammer magazine.

All tracks are written by Cave In.
