"Geyser" is a song by American singer Mitski, released on May 14, 2018, as the lead single from her fifth studio album, Be the Cowboy.

It's gone through many iterations; probably people who went to school with me, who've been in seminars with me, are like "wait, I heard that somewhere..." And then I finally got to a point where I was like "you know what, I need to end this, I'm never gonna be happy with it so let me finish it."

"[4] Vice wrote that the song features "ominous organ sounds and Mitski's trademark sonic swell.

Mitski's lyrics – always gut-wrenching – echo the song's build, as she sings on the chorus 'Though I'm a geyser / Feel it bubbling from below'".

[7][8] The Fader wrote that the video takes place on "a gloomy and funereal beachside while Mitski strikes desperate movements that hit at the longing at the heart of the song.
