Unholy Passion is the first EP and second overall release by American deathrock band Samhain, Glenn Danzig's band after the disbanding of the Misfits. According to bassist Eerie Von in his photographic book Misery Obscura, the album was "a departure from our first release: more underground, more tribal. A step back further into the darkness". The song "All Hell" is a re-recorded version of the Misfits' "All Hell Breaks Loose".
