Slaughter in the Vatican is the debut studio album by American thrash metal band Exhorder, released through Roadrunner Records in 1990. It was reissued by Roadrunner in 2003 in a double disc package with The Law, and reissued again in 2008. The album saw the band compared with Pantera, with Allmusic commenting on the album's "death metal-style double kick drums, chugging guitar riffs played at both slow and blistering tempos, and, to top it all off, the gruff but very expressive lead vocals of frontman Kyle Thomas".
