Hail Satanas We Are the Black Legions is the first studio recording by French black metal band Mütiilation.

The recording pays a direct homage to The Black Legions, which Mütiilation had recently joined at the time of the EP's release.

It was issued as a 7" vinyl EP (331⁄3-rpm).

[1] The EP was re-released by Nightmare Productions in 2006, with full permission of Meyhna'ch.

The album cover uses an engraving by Claude Gillot (1673 – 1722), depicting several nightmarish creatures.
