"Sleepwalker" is a song that Finnish symphonic power metal quintet Nightwish made and performed during the national Finnish Eurovision Song Contest tryouts in 2000. Although they placed first in the Finnish televote, the jury overruled them, selecting Nina Åström instead. A line from the song ("end of innocence, unending masquerade") was later reused as the title of the 2003 Nightwish DVD End of Innocence.
