"Green Machine" is a song by Kyuss from their 1992 album Blues for the Red Sun. Written by drummer Brant Bjork, it was released as a single that same year.

The back of the CD case contains the following review:

The skyscraping amp inside the CD slick of Blues for the Red Sun - the second meisterwork by Palm Springs, USA natives, Kyuss - just looks loud. It's an image that recalls another era. A time when the battle wasn't to get into the pit but to put your head into one of the bass bins of the PA system. It used to be called fun though it played hell with the pressure in your ears. Maybe the gents in Kyuss used to get up to similar tricks and have set out reproducing those same sounds that pushed them to the brink of passing out. They certainly look like something straight out of a worn promo shot of crazed sixties decibel barbarians, Blue Cheer and sound that almost unbelieveably [sic] at times like a street punk version of the original Black Sabbath. Now let's face it - who doesn't need that. Yep, Kyuss are out to move your head and bowel and make the earth beneath your feet shudder. Mighty noble ideas if you ask me.

The video for Green Machine features bassist Scott Reeder instead of Nick Oliveri, who left the band shortly after the release of Blues for the Red Sun.

The Japanese doom metal/stoner rock band Greenmachine named themselves after the song.

Dutch breakcore musician Bong-Ra sampled Green Machine on his track "Suicide Speed Machine Girl" from his 2006 album, Stereohype Heroin Hooker.

In 2006, the alternative metal band Emil Bulls covered Green Machine on their acoustic album The Life Acoustic.

In May 2008, post-metal group Pelican debuted their first music video, "Dead Between the Walls." With "sand, fast cars, blistering colors, and just a focus on rockin’," the video was intended as an homage to the "Green Machine" video.
