"Cosmogony" is a song by Icelandic artist Björk, released as the second single from her eighth album Biophilia. The song was released on iTunes on July 19, 2011. It was also released as an app, which served as the "mother app" for the Biophilia app. It was released as part of The Crystalline Series alongside the first single from the album "Crystalline" on CD and vinyl.

In January 2011, when the app Solar System by Touch Press was released, it was accompanied by an instrumental introduction written by Björk. This song was the instrumental version of "Cosmogony". In March 2011 it was announced that Björk would play at the Manchester International Festival with a new concept of concert. Several songs from the album debuted during a series of performances at the festival between June 27 and July 16, 2011. Björk called the performances a "meditation on the relationship between music, nature and technology"."Special" instruments were designed and constructed specifically for these concerts.

"Cosmogony" is a calm and warm song, marking the link between the previous Björk project, Volta and Biophilia, using distorted brass, but in a much more intimate soft way. The lyrics to "Cosmogony" are also far from the rest of the songs on the album, while those are focused on technic or metaphoric facts about a natural phenomenon, the "Cosmogony" lyrics turn into a philosophic view, based on several myths about the creation of the universe. Björk explained:

Björk also considers the song as some kind of joke, branding the Big Bang theory as a 20th-century creation myth:

Every song on Biophilia has an app for iPhone or iPad. The main app was released on July 19, 2011, coinciding with the release of "Cosmogony", and it integrates all the songs' apps.

"Cosmogony" is the "mother app" that consists of the main menu of all of the other apps connected to Biophilia. Visually, it is a 3D universe designed by M/M (Paris) that can be explored that includes shortcuts to the rest of the apps.
