Illud Divinum Insanus is the eighth studio album by American death metal band Morbid Angel.

Illud Divinum Insanus is the band's only album featuring Norwegian guitarist Destructhor, the first with bassist/vocalist David Vincent since Domination (1995), and the first to not include longtime drummer Pete Sandoval, who had undergone back surgery when recording began.

[2] Vincent said that with the exception of "Omni Potens", which features a "march" programmed by him on a keyboard, all of the album's instrumentation was "played".

Work on the album began in 2006,[citation needed] and it was originally going to be released in 2007, but was pushed back several times while the band continued touring and writing new material.

[5][6] According to Vincent, the songwriting process for Illud Divinum Insanus differed from Morbid Angel's previous albums.

It was designed by Brazilian artist Gustavo Sazes, who commented: To create this cover we worked from several references, ideas, elements, and I would say a 'world' of options and paths.

After a long brainstorming period and some [good and bad] ideas left behind, we came up with the concept of this organic surreal insane being; a fallen God or a weird mirror image of our own madness.

Of all the remixes I've been asked to do I never expected one of the world's most notorious death metal bands to have an interest in hearing their music on the dance floor.

"[22] Sandoval was unable to contribute to the recording of Illud Divinum Insanus due to injuries, and later left the band entirely.
