Hvarf/Heim is a compilation album by Sigur Rós. Its original CD release comprises two discs: Hvarf contains studio versions of previously unreleased songs, while Heim contains live acoustic versions of songs already released. The songs on Heim are the same recordings found in the documentary Heima. In 2008 EMI released a single-disc version in which Heim is simply tracklisted to follow Hvarf. In 2012, the albums were issued on vinyl for the first time to be sold on Record Store Day.

Sigur Rós is an Icelandic post-rock band that formed in 1994 in Reykjavík. It comprises lead vocalist and guitarist Jón Þór "Jónsi" Birgisson, bassist Georg Hólm and keyboardist Kjartan Sveinsson. Known for their ethereal sound, frontman Jónsi's falsetto vocals, and their use of bowed guitar, Sigur Rós incorporate classical and minimal aesthetic elements. Jónsi's vocals are sung in Icelandic and non-linguistic vocalisations the band terms Vonlenska. They have released eight studio albums, and attracted critical and commercial attention with their second album Ágætis byrjun.
