Nightwish is a Finnish symphonic metal band from Kitee. The band was formed in 1996 by lead songwriter and keyboardist Tuomas Holopainen, guitarist Emppu Vuorinen, and former lead singer Tarja Turunen. The band soon picked up drummer Jukka Nevalainen, and then bassist Sami Vänskä after the release of their debut album, Angels Fall First (1997). In 2001, Vänskä was replaced by Marko Hietala, who also took over the male vocalist role previously filled by Holopainen or guest singers.

Nightwish is the third-best-selling band and musical entity in Finland with certified sales of nearly 900,000 certified copies. The group is also the most successful Finnish band worldwide, selling more than 10 million records and receiving more than 60 gold and platinum awards, having released six Number 1 albums and thirteen Number 1 singles. On October 26, 2018, Nightwish was inducted into the Finnish Music Hall of Fame, becoming the honorary gallery's 11th member.
