Castiel: This is a den of iniquity. I should not be here.
Dean: Dude, you full-on rebelled against Heaven. Iniquity is one of the perks!
Also known as a "house of ill repute", a Den of Iniquity is typically a room, auditorium, or stadium in the Evil Overlord's Evil Tower of Ominousness or Island Base where all sorts of sin and wrongdoing takes place. Although towers are in short supply nowadays, if the Big Bad happens to make and/or enforce the laws they might have one in their mansion (but explaining them to less debauched guests might be tricky).
The level of debauchery will vary according to the setting in question; family-friendly stories might make it a lounge for the Mooks to gamble, get drunk, and brawl (not necessarily in that order), while Darker and Edgier works might go for rape, torture, and blood sports.
The Den of Iniquity is often a hangout for the Mooks or Faceless Goons who need something to keep them entertained when they're off-duty. On the other hand, whether the Big Bad or The Dragon indulges in the debauchery depends on where they stand on the Sliding Scale of Antagonist Vileness.
Often populated with the Paid Harem and Bodyguard Babes. The Den of Iniquity isn't restricted to "evil" characters (as Miss Kitty can usually attest), but most heroes will simply find it beneath them.
Specific underground locations are the Torture Cellar and Locked in the Dungeon. Compare Opium Den. Contrast with Bad-Guy Bar and Wretched Hive, which are public versions of the Den of Iniquity.
Examples:
- Babel Tower from the beginning of the second season of Code Geass. Gambling, blood-sports, waitresses in bunny-girl outfit... and particularly rich and influential guests could indulge in 'rabbit-hunts'. It's never specified exactly what that means for the caught 'bunnies', but one can make reasonable guesses. Unfortunately for one mafia-boss, however, he happened to catch a Killer Rabbit...
- The Amazon Trio of Sailor Moon Super S has a more subdued example in the form of a bar with a lone saxophone playing to lounge in-between missions.
- The late chapters of Genocyber feature the political elite hanging out in a secret, luxurious and decadent bar with drugs, prostitutes, gambling and torture shows. It serves to drive home the stark Orwellian dystopia the world has turned into, with the powerful people carrying on lives of luxury and excesses while the proletariat is constantly watched, exploited, killed and made miserable.
- Hellblazer: In "Mortification of the Flesh", we learn that the Vatican has one, specifically, a room enchanted to be hidden from the eyes of God so that whatever is done in there isn't a sin. Built by Pope Alexander VI, who you may know better as Rodrigo Borgia. And the room certainly lives up to its reputation, having seen theft, fornication, murder, demon summoning... in that chapter alone.
- In L'épée de cistal, there is one that is also a "stock exchange of sins": the minions shout the name of one of the Seven Deadly Sins, and by that means influence people all around the would to commit those sins.
- Old Town in Sin City is an entire city district of iniquity, what a Red Light District would be if it was openly owned by the ones providing the "entertainment".

- The symposium that it's shown in the third chapter of Democracy takes place in a room full of gorgeous courtesans and crazy jugglers.
- In the Empath: The Luckiest Smurf story "Smurfed Behind: The Other Side Of The Mirror", Tapper's Tavern in the Mirror Universe version of the Smurf Village is pretty much this, with gambling, smoking, fighting, lots of obscene language, and immoral affections going on between the Smurfs. Not that the village itself is any better by comparison.
- The opening song in Aladdin (yes, the Disney version) has the protagonist in a place with some scantily clad harem girls, who clearly know who he is.
- In Toy Story 3, there is a humorous example of a bunch of 'bad' toys hanging around in a vending machine, betting with Monopoly money and triple A batteries. They use a "Speak-And-Say" toy instead of a roulette table.
- The Thief and the Cobbler has the two main villains meet in one of these. Mighty One-Eye keeps a harem of scantily-clad women in his camp, some of which he uses as a throne (or a couch), while others belly-dance for his entertainment. Grand Vizier Zigzag approaches the Mighty One-Eye while this harem is on full display.
- The Best Little Whorehouse in Texas trope codifier.

She discovers the fake clients set up for her cannot be relied upon and when faced with real tricks decides to sew her "Wild oats" and enjoy a sexual adventure as a real prostitute, transforming from tomboy into Fair Cop via a Girliness Upgrade, essentially Becoming the Mask. Also played with when she does a roleplay as a (dominatrix-y) cop for one of her unwitting clients and indulges in A Three Some Is Hot with an attractive married couple.

As Harry recognizes, you can find anything you want in Club Zero...except fulfillment or meaning or love.

- In Caliphate, Castle Noisvastei is a bordello operating under a fundamentalist Islamist state. Even though prostitution is punishable by death in states like Taliban, it's tolerated under Islamist-controlled Germany where female Christians are kept as sex slaves, but Muslims can also be sent there if their husbands divorce them. It gets much worse when there are also women brainwashed with mind-control devices to be used as cheap pleasure for the customers.
- Appears in The Eye of Argon as part of its massive collection of stock fantasy cliches.
- The Handmaid's Tale has Jezebel's, one of the few establishments left in Gilead where prostitution is permitted, but only to entertain the men. It passes itself off as a Smoky Gentlemen's Club to make it seem respectable in the face of the country's own moral hypocrisy as a supposedly "God-fearing" theocratic state.
- In Kim Newman's The Hound of the D'Urbervilles, Professor Moriarty has his apartment and criminal base in a building which has as its first floor a brothel, and his number two, Colonel Moran, often indulges himself with the "other employees." Moriarty himself seems to have no sex drive.
- The term "Den Of Iniquity" first appears in Robert E. Howard's story "Texas John Alden".
- In Being a Green Mother, we find that Satan runs Mock Hell, where all types of sin can be indulged in, for "merely" a percentage of evil on your soul.

- Beverly Hills Bordello, an anthology series set in an exclusive whorehouse.
- In the Buffy the Vampire Slayer episode 'Into the Woods' Buffy raids and destroys a vampire brothel she has caught her boyfriend Reilly cheating on her in. In this case it's portrayed more like a crack den, with the Kiss of the Vampire being used as a drug metaphor.
- Whilst it has numerous other attributes the eponymous Dollhouse is the ultimate fantasy brothel where they "Make better hookers".
- In Eagleheart, a bizarre bylaw makes it legal to do anything in the sky. Everything goes, up to and including murder. Naturally, a crime baron sets up a blimp as his base of operations where every type of crime is indulged and encouraged (except smoking, because of the hydrogen)
Chris Monsanto: So what you're saying is that everything is legal in the sky, and there's a huge crime blimp floating around? I wonder how I missed that.
- Joked about on an episode of Empty Nest, where Harry (a man in his 60s) begins a May–December Romance with a woman in her 30s. When the woman's parents, who are around the same age as Harry, decide to visit, her father angrily glares around the room upon arrival:
Her father: So this is the den of iniquity!

- Hercules: The Legendary Journeys: Salmoneus is shown in "Under the Broken Sky" managing what's described as a pleasure palace, much to his displeasure. He insists to Hercules that he didn't know it was this kind of establishment, saying his brother-in-law (the owner) lied about it being a nightclub and stuck him with overseeing things while away on business. As to be expected, Hercules doesn't much care for the place, either, calling it a pit. The episode's conflict stems from one of the workers, Lucina, who fled home out of guilt after her children died of sickness. Her husband, Atticus, has tracked her down to implore to return home, but she's also caught the eye of the local gang leader. After Hercules takes down the gang and husband and wife reconcile, the locals decide to improve the town's seedy image by turning the den into a senior citizens' center.
- Tiberius' mansion in I, Claudius has one of these. The historical Tiberius, on the other hand, did not want and did not need one of these: an antisocial prick but able administrator, he preferred to spend his time mostly alone in his pleasure palace on the island of Capri, and according to Roman historian Suetonius, "indulging his pedophilic predilections" in private. Although later research showed that Tiberius went to Capri mostly because he wanted to hide from assassins and read in peace.

- Supernatural sees Dean haul the angel Castiel to a brothel the night before said angel expects to perish in a confrontation with the archangel Raphael. The incredibly strait-laced Castiel reacts predictably.
Castiel: This is a den of iniquity. I should not be here.
Dean: Dude, you full-on rebelled against Heaven. Iniquity is one of the perks.- It takes a hilarious turn when Castiel gets invited into a backroom with one of the girls. Moments later she runs out of the room shouting obscenities at him. Cas apparently read her mind, and casually told her it wasn't her fault her dad left her family when she was little. Dean and Cas are forced to leave post-haste when the bouncers show up.

- On each studio-album-proper, Joy Division had a song describing one: "Day of the Lords" on Unknown Pleasures, and "Atrocity Exhibition" on Closer (the latter's title is a Shout-Out to JG Ballard).
- In the Book of Jeremiah (of The Bible), God condemns the Jews for treating His Temple like "a den of robbers" by breaking all the commandments except for "keeping the Sabbath holy" (by implication), declaring that "we are delivered" so that they can continue doing their abominations. (The same description is used by Jesus in the Gospels when He goes into the Temple to clean it out of the marketers and money-changers violating her sanctity — an image made much more vivid in the theatrical and stage productions of Jesus Christ Superstar.) In the apocryphal book of 2nd Maccabees, the Temple is actually reduced to this with the introduction of pagan revelry by Antiochus Epiphanes, including sex workers and roasting abominable meats.
- Dungeons & Dragons:
- Compared to the other layers of the Abyss, Shendilavri seems like a paradise, a picturesque land of gardens and marble cities beneath an eternal sunset, where the locals welcome visitors into a life of luxury, passion and indulgence. Unfortunately it's also the capital of Malcanthet, Queen of the Succubi, so its demonic citizens tempt mortals into increasing depravity until their souls are utterly corrupted, and beneath the beautiful facade are hidden dungeons and torture rooms.
- The Nine Hells of Baator are for the most part grimly dedicated to the business of combating the demonic hordes and processing damned souls, but on the layer of Maladomini is a place where devils can unwind. Baatezu can exchange harvested souls for a stay in the Carnival Eternal, where they can enjoy a reprieve from their usual duties ranging from one day for 9 souls to two millennia for 999 souls. "The tortures and debauchery engaged by vacationing devils are best described in vague terms to players."

- Girl Genius: In a quick flashback Gil is shown someplace Tarvek seems to have considered to be Gil's Den of Iniquity in Paris, though it's implied to have been at some kind of bar, brothel or Opium Den so it wasn't in reality, surrounded by scantly clad women with something rather bong looking mostly cut off at the edge of the panel.

- Looney Tunes: The Kit Kat Club in "Tin Pan Alley Cats" (1943) is deemed a den of iniquity by the pastor of Uncle Tomcat's mission. He pleads with the cartoon's protagonist not to go in "or you will be tempted by wine, women and song." The little guy's response: "What's de mattah wit' dat?!"
- The Venture Bros. showed a low-key example of this in the fourth season, a room inside the Monarch's cocoon where his minions would quietly gather for drinks on their downtime.
