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.

[2] In 1987, Danzig re-recorded the guitar and some vocal tracks for the songs, removing the original work done by Pete "Damien" Marshall.

The recordings were given new mixes and, with the addition of "Misery Tomb", were released as part of Final Descent in 1990.

The remixed versions were released as a standalone CD for the first time as part of the Samhain box set in 2000 and as an individual CD in 2001.
