Demon Name Generator — 750+ Infernal, Sulfur-Breathed Demon Names

What Makes a Demon Name Sound Infernal?

Demon names carry the weight of the Ars Goetia — the medieval grimoire listing the 72 spirits of Solomon. They're ancient, harsh, and hierarchical, built from Latin and Greek roots with thunderous endings: -on, -ax, -oth, -ar. Names that sound like they were carved into obsidian by something that predates humanity.

Say it like a threat: Astaroth. Belial. Infernax. Mammon. These names don't just label a demon — they announce its rank, its domain, and its danger. In the grimoire tradition, a demon's true name is a key to commanding it; the name is power.

Demon Name Elements and Their Meanings

The pattern: demon names draw from hell, fire, night, rage, evil, and destruction — plus the theophoric structure of the Goetia (Baal-, -oth, -ael), which gives them the sound of ancient summoning texts.

The Goetia Tradition

The 72 spirits of Solomon are the gold standard of demon naming. Their names follow consistent patterns:

1. -oth / -oth endings — Astaroth, Dagon, Beleth. These read as ancient and formal.

2. Baal- compounds — Baalberith, Baalzebub. "Lord of ___" — a rank marker.

3. Rank titles — King, Duke, Earl, President. In the Goetia, every demon has a title, and the title matters as much as the name.

If you want an authentic-feeling demon, borrow the structure: a strong root (Infer-, Mort-, Umbr-) plus a Goetia-style ending (-oth, -ax, -ael), plus a rank title. Infernax, Duke of the Ninth — instantly credible.

A Note on Demon Culture

In the grimoire tradition, a demon's name is its contract — knowing it grants power over it, which is why demon names are treated as dangerous secrets. The name encodes rank, domain, and nature: Mammon is greed, Abaddon is destruction, Belial is lawlessness. When you name a demon, you're defining what it rules and what it represents — make the name carry the threat, and your players will treat it with the respect it demands.
