The Dark Sides is a compilation of King Diamond songs, released on 1 November 1988 through Roadrunner Records.

The album cover featured King Diamond with face paint that resembled KISS bassist Gene Simmons' "Demon".

Simmons claimed that King's face paint was copyright infringement and sued him.

The lawsuit was eventually dropped when King changed his design.
