Vastum is an American death metal band, formed in 2009 in San Francisco, California. The current line-up of the band consists of guitarist and vocalist Leila Abdul-Rauf, vocalist Daniel Butler, drummer Adam Perry, guitarist Shelby Lermo, and bassist Colin Tarvin.

The band is noted for its lyrics, which deal with themes such as sexuality and eroticism, and are influenced by French writer Georges Bataille and psychoanalyst Jean Laplanche. Musically, the band's releases feature a death metal sound based on "slow to mid-tempo, grinding grooves, interspersed with up-tempo shifts, and a bellowing, enunciated growl."

The band's third studio album, Hole Below, was listed as number 19 on Pitchfork's list of "The Best Metal Albums of 2015."
