"Cocoon" is a song by Icelandic singer Björk for her fourth studio album, Vespertine (2001). Written and produced by Björk and Thomas Knak, it was released as the album's third single on 11 March 2002 by One Little Indian Records. Inspired by her relationship with artist Matthew Barney, Björk wanted to create a record with a domestic mood.

Music critics received "Cocoon" with positive reviews, calling it one of the album's highlights.

It depicts Björk as a geisha whose makeup extends over her entire bleached nude body. The video was considered inappropriate and was banned from primetime MTV, following her music video for "Pagan Poetry". Björk promoted the song by performing it on the Vespertine World Tour and several television and radio shows. Background and development In 2000, Björk starred on her acting debut Dancer in the Dark.

She had to go to Denmark to work on the film and there was nothing going on. She was lying on the beach whilst looking at the ocean, with a ghetto blaster listening to producer Thomas Knak's music. When she realised he was from Copenhagen, she called him up". "Cocoon", produced by Knak, was one of the last songs to be written for the album; its melody came to Björk in a sudden rush and she contacted him. She made a long-distance, late-night phone call to Knak in Denmark, and woke him up. "I didn't have any track of time so she didn't really know that I was asleep. She was explaining that she had this melody in her head and maybe, if I had the time, she would still have
