Altars of Madness is the debut studio album by Florida death metal band Morbid Angel, released on May 12, 1989, by Combat Records/Earache Records.

Considered a groundbreaking and important release in extreme metal, Altars set a new precedent for heaviness and extremity in both lyrics and instrumentation. It is one of the most celebrated albums in death metal, and one of the most influential heavy metal albums of all time.

The album features a number of tracks that were originally recorded for what was supposed to be their debut album Abominations of Desolation, originally recorded in 1986 but which was only released in 1991.
