Myrkur is a solo black metal project by Danish singer Amalie Bruun. Initially, the real-life identity of the person behind the project was kept unknown. Her identity has since been made public. Myrkur has released four full-length studio albums to significant critical acclaim, as well as a live album and two EP. Her most recent album, Spine, was released on 20 October 2023 through Relapse Records.

The name of the project comes from an Icelandic word meaning "darkness." The musical influences of Myrkur range from traditional Scandinavian folk to the black metal genre. New releases from Myrkur have tended towards embracing folk music traditions, with Bruun's 2020 album Folkesange being overwhelming folk-inspired and lacking the black metal sound that characterized the artist's earlier releases. Folkesange contains narrative "story-songs" performed on instruments appropriate to the ancient pagan folk music that Bruun included within the album, alongside modern original compositions as well.
