Κατά τον δαίμονα εαυτού (transliterated: Katá ton Daímona Eautoú) is the eleventh full-length album by Greek extreme metal band Rotting Christ.

The album incorporates diverse instrumentation, including bagpipes and horns, and delves into Incan, Persian, Babylonian, Mayan, Romanian, Slavic, and Greek mythology.

Rotting Christ frontman Sakis Tolis considered the album "a journey into the knowledge of ancient civilizations and into the occultism that is rising from the dark side of each one of them".

Sakis Tolis contended that the label's understanding of the phrase was "do what thou wilt", [verification needed] a quote associated with Aleister Crowley and Thelema.
