Pain (typeset as PAIN) is a musical project from Sweden that mix heavy metal with influences from electronic music and techno. The project started out as a hobby project for front man Peter Tägtgren, whose idea was to fuse heavy metal with 1980s-inspired electro-industrial and techno influences. Tägtgren, who is also the vocalist/guitarist of Hypocrisy and producer of his own The Abyss studios, is the only current member.

Pain's self-titled debut was released in 1997, and since then Pain has released six more albums and a DVD. Starting with their second, all of Pain's albums have made the Swedish charts, thanks in large part to hit singles such as "End of the Line", "Shut Your Mouth", and "Same Old Song". In early February 2006, Blabbermouth.net reported that Pain had signed with Roadrunner Records. Currently, Pain is under the Nuclear Blast Records banner.
