Demon Entrails is a compilation album that comprises three demos by the Swiss extreme metal band Hellhammer. The demos – Death Fiend, Triumph of Death and Satanic Rites – were all recorded during 1983 and were properly remastered for this compilation.

The music on Demon Entrails is considered to be primitive, drawing influence from Venom. According to Phil Freeman of AllMusic: "Hellhammer's riffs could be played by a chimp wearing boxing gloves, but they've got the same crunching power as songs by Motörhead, Discharge, and the Melvins, other groups with a keen understanding of unsubtlety." Tape hiss is audible on the album. The album's equalization and mix is considered to be "bass-heavy". Freeman said: "This music is a runaway bulldozer, the sound of three pissed-off young men cranking the amps and releasing all their frustration and misanthropy as fast as possible." The album's lyrics explore themes such as gore, damnation, and demonology.

There exists a deluxe release of the album that includes "full lyrics and a booklet full of rare photos," according to Phil Freeman of AllMusic.

Phil Freeman of AllMusic gave the album a score of four stars out of five. He wrote: "It's no wonder Hellhammer's demos have been cited as an influence on pretty much the entire Scandinavian black metal scene, not to mention the young ladies of Japan's Gallhammer. Over 25 years later, this is still extremely powerful stuff, and the lavish packaging gives it the respect it deserves."
