Amiina (formerly Amína and Aníma) is an Icelandic band composed of Hildur Ársælsdóttir (born January 31, 1980), Edda Rún Ólafsdóttir (born February 3, 1978), Maria Huld Markan Sigfúsdóttir (born September 29, 1980), and Sólrún Sumarliðadóttir (born August 10, 1977). They frequently perform live and in the studio along with Sigur Rós. Back in 2001 violinist Ólöf Júlía was part of the band but has since been replaced by Hildur Ársælsdóttir.

The music is made with a great number of instruments. It contains elements of minimalistic style, contemporary classical, ambient, and electronic loops. In their performances, each of them plays from the large range of instruments, moving from one instrument—and side of the stage—to another mid-song, often after sampling.

When Sigur Rós ceased touring in July 2006, Amiina followed with their first solo tours of Europe and America.
