"Náttúra" is a song written and recorded by Icelandic singer Björk. The track was released as a single promoting the protection of the Icelandic environment. All proceeds from the single will be donated to the Náttúra Foundation, the environmental preservation campaign after which the song is named. The single was initially discovered by Björk's French language fan website and was later confirmed by the singer's representatives. It was released on October 20, 2008 as an iTunes Exclusive, and had a wide digital release on October 27. The song was given a physical release on April 20, 2009 with a white label vinyl released by One Little Indian's web shop.
This is Björk's first solo single to be released entirely in Icelandic. It is also the first not to have a corresponding album or video. However, it is bundled with the digital download and included on the digipak edition of Björk's 2011 album Biophilia.
