Frequently, when a character enters an evil or cursed area, they'll find that it smells really, overpoweringly bad. It usually smells of rotten flesh (or just "death") and grows more powerful as the investigator gets closer to the threat. Another variant is an evil being carrying a bad stench with it when it appears. Frequently one of the Horror Tropes.
This trope stems from the fact that dead and unclean things smell bad, so if somewhere or something smells bad, it's probably dangerous. The belief that demons smell of sulfur is also a contributing factor.
Compare with Uncleanliness Is Next to Ungodliness, where the stench is just a character's poor hygiene. Can cross with Stink Snub should a character comment snarkily on the villain's odour. Please note that the smell of evil isn't always proportionate to its taste.

- Watanuki from ×××HOLiC came across some situations like this, but he's the only one who can sense it. One example is at Himawari's friend's school where the game, Angel, is taking place.

- Gyo lives off this trope, since the monsters in question are undead fish corpses. Even living fish doesnt exactly smell good. As it turns out, the corpses are just a delivery system, the true evil is a form of semi-sentient bacteria that propogates itself using the gasses released by decay. It's even worse for infected humans since they aren't technically DEAD.
- Lupin III (Red Jacket)': in the episode Killing is the Smell of Wine, professional and amoral Psycho for Hire Hangman has both the ghoulish looks and the smell of a corpse.

Captain Jack Sparrow: Not that bad, really.
- The Three Mothers Trilogy (which consists of Suspiria, Inferno and Mother of Tears) more specifically invoke this, by mentioning that the earth that witches' houses are built upon becomes so deadly and pestilent by the evil and death that emanates from there, that the entire neighborhood has a sweetish, nauseating smell.

- In Gary Jennings's Aztec, the Spanish conquistadors rarely bathed, according to the European customs of the time (mid-to-late 1400s).

- In Dracula, the eponymous villain has foul breath, almost certainly due to his diet, and areas where he stays are, well, to quote the book:

- In Shadows of the Empire, Prince Xizor notices something.
He imagined he could smell the decay in the Emperor's worn body. Likely that was just a trick of the recycled air, run through dozens of filters to ensure that there was no chance of any poison gas being introduced into it. Filtered the life out of it, perhaps, giving it that dead smell.

- In Re:Zero, the Witch of Envy and the people favored by or connected to her have a distinctive foul scent, though (outside of the dense miasma produced by the Witch herself) only a small number of characters can smell it. Since Subaru's ability to return to life comes from the Witch, he reeks more and more of her scent on each revival, which makes other characters have a hard time trusting him. Because monsters were created by the Witch of Gluttony, who was betrayed and killed by the Witch of Envy during her rise to power, they also have a special hatred of this scent and seek out its holders to attack them.

- The Elder Scrolls
- This is said to be the case for Scamps, the weakest and smallest known form of lesser Daedra who have a rancid smell.

While Scamps are generally in the service of Mehrunes Dagon, the staff was created by Sheogorath, the Daedric Prince of Madness and a morbid practical joker.
- The Sload are a race of "slugmen" native to Thras, an archipelago to the southwest of Tamriel. While they themselves operate on a Blue-and-Orange Morality, the denizens of Tamriel instead see them as Always Chaotic Evil.

- Coldharbour is the Daedric plane of Molag Bal, Daedric Prince of Domination and Corruption. The ground is sludge, the sky is on fire, and the air is freezing. It resembles a ruined and desecrated copy of Nirn that is filled with suffering and "spattered" with blood and excrement. It contains charnel houses full of the dead and slave pens beyond count. If that weren't all horrifying enough, it is said that the smell alone is enough to break most mortals. It is said that no mortals willingly visit this place except in error.
- Moshi Monsters: Played with. None of the evil locations smell bad and most of the villains don't, but the Glumps, an Always Chaotic Evil Servant Race created by the villains, and by extension the goo they secrete, smell like rotten fish and sweat.

- Reasoning has the Venator, a monstrous rat-like creature that smells like garbage and carrion.
- A few shorts of the Japanese horror anthology "Tales of Terror From Tokyo" dealt with this trope, including "The Smell", where a young girl comes upon a kneeling woman who always faces her back and stinks of rotting meat (for some reason, the smell prompts her to try to call the police right before the ghost woman does her wacky hijinks on her ), and "The Smell of Animal", where the visiting niece is the only character who finds her aunt's husband has a horribly repulsive smell. Through flashbacks, it's revealed that, in his youth, the husband enjoyed killing animals as a hobby and the smell latched onto him .
- The Legatum series zig-zags this trope constantly. A lot of characters are noted for not bathing at all—villains and heroes alike.

Even King Chorn Torgash, one of the cleaner villains, has bad breath and smelly feet.
- The Grim Adventures of Billy & Mandy: A sleepless Billy imagines his own bed time story where there was a town so happy that it Tastes Like Diabetes watched over by an evil wizard.

- In Peppermint Rose, Bugoonya as a whole smells nasty, but the queen's smell is so bad anyone who comes near breaks out in sneezes.
- In the Masters of the Universe franchise, there's the villainous Stinkor, pictured above. In the 2002 cartoon, Stinkor was actually one of Skeletor's more effective minions, his constantly produced stench gas so powerful it could cripple even He-Man. At one point, it was used to cause a stampede, the herd animals desperately trying to escape his stench.
- The Plutarkians from Biker Mice from Mars were a race of fish-like aliens who stole resources from other planets and also tended to smell horrible.

- David Sedaris says that crickets don't just smell bad, they smell evil.
- According to veteran stories, battlefields stink. Burnt wood, metal and rubber, rotting dead bodies, burning oil and fuel, decay and mud. Burying the dead and removing the debris from the fields is a foremost task in the aftermath of a battle, before diseases set in. Obviously, the Western Front of World War I is the worst with a years long stalemate allowing all these problems to pile up to a degree and scale no-one imagined possible before.
- Pirates, like most sailors at the time, would sometimes go for days or weeks without bathing due to the lack of clean freshwater on board their ships.
- A few of Derek Lowe's "Things I Won't Work With" are chemicals which, when not being Explodium, are overpoweringly smelly as well as toxic. Worse, some of them aren't even that toxic, but are simply so utterly, overwhelmingly stinky that chemists who allow it in their labs are rare. The fact some of them can be smelled half a mile away when you spill a single droplet doesn't help, either. Selenium compounds seem to be particularly common offenders.
- Reportedly, you could always tell when a slave ship came to port; they stunk to high heaven with the combination of human waste, blood and other substances resulting from their chained cargo and their crews were often the worst paid and behaved of any kind on the sea.
- Serial Killer, Richard Ramirez, would invoke this on purposenote by never bathing nor brushing his teeth. He ate a lot of candy and other sweet stuff and his teeth were a mess. Surviving victims would describe him as smelling like wet leather with breath like liquid feces.
- An inversion would be the saying "cleanliness is next godliness" i.e being clean and smelling nice is associated with goodness and virtue.
