Disease Name Generator
Our Disease Name Generator creates names for fictional plagues, fevers and curses, from “Greywither” to “The Weeping Bone Fever.” It suits D&D campaigns, novels and games where an outbreak drives the plot.
Click for five names, click again for more, and copy any name with the icon beside it. Every name is invented for fiction, so none refer to real illnesses on purpose.
How diseases get their names
In history, most names came from what people could see, because a visible symptom was all anyone had to go on. The Black Death, the sweating sickness and the Great Pox all describe a symptom, and a name like that spreads faster than any medical term.
Names also came from places and blame. Today the World Health Organization advises against naming a new disease after a place, a person or a group of people, because the label can cause harm. Your world may not follow that rule, and a town that names its plague after a rival city has a story ready to go.

A plague in three lines
Pick one name and write three sentences. Take Greywither.
Greywither turns the skin the color of ash over about a week, and the sick stop sweating before they stop walking. Healers in the harbor quarter blame the salt trade, while the salt guild blames the healers. The party arrives the day the quarantine bell rings.
The name does the work because it holds the symptom, the speed and the mood. Each of the three sentences follows from it.
Why people use two names
A single disease usually has a scholar’s name and a street name. The healers call it Morbosis, and the market calls it Widow’s Lung.
Use that split at the table, because a player who asks a healer gets one name, a player who asks a ferryman gets another, and the gap tells them who knows more.
Building an outbreak
A good outbreak has a source, a symptom, a cost and a cure. The name should hint at one of them. “Moonrot of the Low Marsh” points to a place, and “Salt Lung” points to the work that causes it.
Give the cause a face with the Necromancer Name Generator or the Villain Name Generator. For the places the sickness reaches, try the Town Name Generator and Tavern Name Generator.
For something stranger than a fever, such as a curse that turns people into something else, the Undead Name Generator and Witch Name Generator are good partners.
Check your plague before you name it
A name feels right when the disease behind it makes sense. Before you commit, answer three questions: how does it spread, who gets it first and what can the party do about it?
If the answer to the first is bad water, the name might mention a well or a river. If it spreads among miners, a name like Salt Lung ties it to the work, so the people most at risk will recognize it.
Cures give you more hooks. A disease with a rare cure, such as a flower that blooms once a year, turns the name into a quest, and the cure needs a name too.
Different cultures can call the same illness by different names. A port city might say Harbor Fever, while the inland farms say the Grey Cough, and the party can work out where it started by comparing the two. For a settlement to quarantine, try the Village Name Generator.
Disease Name Generator FAQs
What is a good name for a fantasy disease?
Name the most visible symptom and add a simple word, such as Greywither or Ashlung. A name people could whisper in a market works best.
Are these names real diseases?
No. They are made up for fiction, though a rare name may resemble a real term by chance.
Why do diseases in stories need two names?
A scholar’s name and a street name show who knows what. The gap between them gives you an instant source of rumor and mistakes.
Can I use these names in D&D?
Yes. They work for plague hooks, cursed regions and healer NPCs in any tabletop setting.
