The Sisters of Mercy are an English rock band that formed in 1977. After achieving early underground fame in UK, the band had their commercial breakthrough in mid-1980s and sustained it until the early 1990s, when they stopped releasing new recorded output in protest against their record company. Currently, the band is a touring outfit only.

The group has released three original studio albums, of which the last was released in 1990. Each album was recorded by a different line-up; singer and songwriter Andrew Eldritch and the drum machine called Doktor Avalanche are the only points of continuity among the line-ups. Eldritch and Avalanche were also involved in The Sisterhood, a side-project connected with Eldritch's dispute with former members.
