"Dear Boss: I am down on whores and I shant quit ripping them till I do get buckled... My knife's so nice and sharp I want to get to work right away if I get a chance."One of the first, and likely still most famous serial killers. Not just a serial killer: The Serial Killer. The failure to conclusively discover the Ripper's identity has made a large contribution to the case's fame, and it is one of the main Stock Unsolved Mysteries used in fiction. The Ripper is commonly held to have killed at least five prostitutes in the Whitechapel area of London's East End during the fall of 1888:
- Mary Ann "Polly" Nichols (31 August)
- Annie Chapman (8 September)
- Elizabeth Stride (30 September)
- Catherine Eddowes (30 September)
- Mary Jane Kelly (9 November)
- Adaptational Attractiveness: Related to the below - a woman addicted to alcohol as at least some of the victims were, after leading the harsh life they did, isn't going to be as pretty when she reaches her forties as the actresses who are usually cast.
- Age Lift: All but one of the five canonical victims were in their forties when they were murdered, but you certainly wouldn't know this from most film or TV adaptations, which cast much younger actresses.
- Ambiguous Gender: A few theories claimed he may have not been a "he" at all, and may have been another prostitute or a woman who had some reason to hate them.
- Beethoven Was an Alien Spy / Epileptic Trees / Shrouded in Myth: The various theories as to Jack's identity, with the former particularly true for the conspiracy-theory ones which involve the royal family.
- The Conspiracy: Some theories maintain that the Ripper didn't work alone; how big the alleged conspiracy may have been is anybody's guess.
- Disposable Sex Worker: A curious aversion, considering how frequently this trope and serial killers are associated; despite the lowly social status of the victims, the killings so horrified Victorian society that they formed the impetus for numerous social reform movements, and the police's inability to locate the killer (and arguably inept handling of the investigation) spurred numerous reforms in the Metropolitan Police and its methods.
- The Dreaded: The mere mention of his name could produce panic in London during his rampage.
- Finger in the Mail: A kidney from the Ripper's fourth victim was mailed to the authorities.
- Flanderisation: After Mary Ann Nichols' murder, the police put out a request for a man seen walking down the street carrying a black bag at around the time of the murder to come forward, because they believed that he might have seen something and been a potential witness. As a result of this statement about someone who was not officially a suspect, practically every fictional depiction of the killer will show him carrying around his weapons and killer-trophies in a black Gladstone bag.
- A Foggy Day in London Town: Most adaptations take place in foggy weather, as was typical for the time period in the UK back then.
- Gaslamp Fantasy: Some stories depict Jack as having been some sort of supernatural creature like a demon or a ghost or a vampire.
- Gender Misdirection: There are those (including Sir Arthur Conan Doyle) who believe the killer may have been a woman, aka "Jill the Ripper." They base this theory on the fact that a woman would have been more easily able to gain the female victims' trust— and if she posed as a midwife, would not have attracted attention if she was spotted carrying bloody clothes.
- Gorn: The Ripper was a Serial Killer who mutilated his victims, so of course. Many details of the crimes are definitely not for those with weak stomachs. How much of this is reflected in works depicting him is left to the creators' discretion.
- Historical Villain Upgrade: The Ripper murders were undeniably gruesome, but he was hardly (as often portrayed) the very worst Serial Killer of all time, or even of Victorian Britain. note The case grabbed the popular imagination mostly due to being sensationalized and notably unsolved.
- I'm a Humanitarian: If the letter about the kidney is authentic.
- Jack the Ripoff: Had quite a few copycats, most notably Peter Sutcliffe aka "The Yorkshire Ripper", as well as Jack The Stripper, who unfortunately was never identified.
- Jurisdiction Friction: Given the location of the killings, there were two competing agencies investigating the murders: The Metropolitan Police and the City of London force. They didn't do a good job of sharing information and had pursued different leads. Also, there were multiple Inspectors and Commissioners overseeing the case, which lead to interpersonal conflicts that hindered the investigation.
- Karma Houdini: In theory and the general conclusion. Some suggest that the fact the murders stopped rather suddenly may mean that the perpetrator could have died or maybe been imprisoned for unrelated crimes, but there's absolutely no way to know for sure.
- The Killer Was Left-Handed: Actually, he wasn't, but the persistent claim that he was shows just how pernicious this trope is. Investigators at the time believed this to be the case—an assumption that may have hurt their investigation.
- Monster Misogyny: The real one's known victims were all women, and that's usually the case in fiction too.
- Murderers Are Rapists: As far as we know, a notable aversion. Of course, the victims were prostitutes and they were mutilated so badly it can't be known what was forced and what was not. He may have subjected his victims to something called Piquerism though.
- The Profiler: In 1988, the FBI published a psychological profile of the Ripper murders; it can be read here. (Of course, since the profile was written a hundred years after the crimes, at best it's an interesting thought experiment.)
- Riddle for the Ages: We'll never fully confirm the identity of Jack: too much evidence has been lost and too much time between then and now makes solving this mystery next to impossible. And yet the allure of the mystery keeps drawing more Gull-Catchers to the dance.
- Serial Killer: The Trope Codifier.
- Serial Killings, Specific Target: Some theories and fictional depictions show one of the victims as more intentional than the others, who are killed as a distraction.
- Significant Anagram: Some of the theories of the Ripper's identity depend on obscure ciphers and anagrams from Victorian writings. One of the more farfetched maintains that some sentences in Lewis Carroll's writings can be anagrammed into confessions to the crimes. (Most serious Ripperologists scoff at this notion, some pointing out that the same twisting could be done with sentences from Winnie-the-Pooh!)
- Technology Marches On: The murders occurred when forensic investigation was in its infancy at best, meaning that much crucial evidence from the crime scenes was overlooked or lost. Attempts to test it with modern techniques have been inconclusive since the evidence has degraded, lost, or been improperly handled over time.
- The End... Or Is It?: While the killings supposedly stopped with Mary Kelly's gruesome death, the lack of a captured suspect and a series of other slasher-like murders in the following years led to fears that Jack had or would "come back". Additional killings elsewhere - notably a similar murder in New York - stoked fears that Jack had moved on to other urban hellholes.
- The Unreveal: The Ripper's identity was never confirmed and probably never will be. New suspects are proposed from time to time, but the evidence is far from definitive and always offers just as many problems as solutions.
- The Unsolved Mystery: The definitive example in modern pop culture.
- Stock Unsolved Mysteries: Making speculation of the killer's identity a very common pastime.
- Victorian London: More precisely late Victorian London, in the final months of the year 1888, but somehow the Ripper murders became one of the defining images and enduring cultural memories from that time. Later artists, such as Alan Moore point out the Ripper murders totally obliterated the optimistic certainty that characterized the era at its height.

- Ghost Sweeper Mikami posits that Jack the Ripper wasn't a single person, but rather a possessed shaving razor that could possess those cut by it, meaning that it was being wielded by the previous victims as it slew the women.
- An early-twentieth-century flashback story in The Kurosagi Corpse Delivery Service has Jack the Ripper's ghost haunting a telescope and possessing voyeurs who use it. The story is notable for its explicit acceptance of the theory that the Duke of Clarence (not actually named, but instantly recognisable from the manga's inclusion of a much-reproduced photograph) was the killer.
- Cain of the Count Cain series investigates Jack after his fiance was murdered. One of the more unusual interpretations of the murders, what with the Magic from Technology raising of the dead among other things.
- In the first chapter of Time Eliminator, the main character is hired to erase these killings from history by a descendant of the detective that worked on the case.
- In Nobunagun the Ripper is reincarnated in the present day as a man named Adam Muirhead. While Adam is a good guy, he's still a rather scary, Ax-Crazy Knife Nut. The finale reveals that the original Ripper was, of all people, Florence Nightingale. She was reluctantly killing women who were unknowingly infected with a deadly man-made biological weapon to prevent the disease from spreading to the rest of the population. Since the ordinary folk would have never believed her, she kept to the shadows and allowed the legend of the Ripper to spread.
- The DCU's first Else Worlds graphic novel, Gotham by Gaslight, features a Victorian era Batman tracking the Ripper to Gotham City. Surprisingly enough, no attempt was made to link him to any of Batman's usual villains. His identity is revealed to be Jacob Packer, an American doctor-turned-lawyer and former friend of the Wayne family.
- The Else World Wonder Woman: Amazonia is set in a world where Jack has become King, and the British Empire is a misogynistic dystopia.
- In the mainstream DCU, Jack the Ripper was Red Jack (a Star Trek Shout-Out), a godlike being who claimed to be both Jack the Ripper and God Himself while fighting the Doom Patrol. Or he was Mary Kelly's boyfriend, encouraged by the demon Buzz from Peter David's Supergirl. Or he was possessed by a different demon, Calibraxis from Hellblazer. Or, just possibly, he was Vandal Savage, and was stopped by Resurrection Man.
- In an early 1970s Superman story, the ghost of the Ripper fell in love with Lois Lane while she and Clark Kent were doing an extended visit with one of his descendants; the ghost arranged a form of mystical time travel to send Lois back to Whitechapel to be murdered by his earlier self so she could join him in the afterlife, only to be foiled by his own obsessions — the earlier Ripper refused to harm Lois because she "was not like the others".
- The Madame Xanadu series also involves the Ripper, but rather than reveal his identity his actions are described by the Phantom Stranger to be the universe's "balancing act" response to actions undertaken by Madame Xanadu centuries ago. As it goes, Jason Blood / Etrigan fathered a child on one of the Ripper's victims, and had she carried the child to term, it would have been the greatest horror that could ever walk the Earth. The Ripper murders were a byproduct of the universe attempting to prevent this from happening, and ultimately succeeded. Afterwards, Stranger, while not actively interfering, does take matters into his own hands, and arranges for the Ripper to fall and break his neck rather than continue, because while he "only observes" what takes place, he was as repulsed as any by the murders, even though he accepted the necessity of them.
- A story in the Justice League of America series fused with H. G. Wells' The Island of Dr Moreau and features Jack the Ripper as an orangutan.
- Alan Moore's From Hell is a deconstructive and metafictional examination of the Ripper murders. The title is a reference to the letter to the Whitechapel Vigilance Committee that contained what was claimed to be Catherine Eddowes' kidney. The graphic novel is considered one of the most detailed and accurate portrayals of the period and setting. It uses a widely discredited theory by Steven Knight as its base, but Moore explicitly states that he doesn't actually believe it. In the Appendix, "Dance of the Gull-Catchers" he states clearly (see the quotes page) that the crime is unsolvable and ultimately people should focus on improving the treatment and protection of sex workers and women in general.
- In The League of Extraordinary Gentlemen, Macheath is Jack the Ripper — he fled to Buenos Aires after the last Whitechapel murder, and returned to London in 1910. Naturally, he never stopped killing. As a sidenote, he claims to have committed the original murders when he was only 19.
- Paul Cornell's Wisdom has the eponymous hero battling hundreds of Jack the Rippers.

- The Buffy the Vampire Slayer comic spin-off "Tales of the Vampires" included a story in which the Ripper was a vampire, the twist being that the policeman investigating turned out to be a vampire as well, who eventually killed the Ripper for being too splashy and risking exposing the existence of vampires to the public.
- A Hellraiser comic reveals that Ripper became a Cenobite.

- In the French Darker and Edgier Prequel to Peter Pan by Regis Loisel, Jack murders Peter's abusive prostitute mother apparently out of pity for him, but still clearly traumatizing the poor boy. Furthermore, it's implied that this event in fact launched the Ripper murders, as it apparently made Jack loathe all prostitutes as abusive monsters.
- The Marvel Universe offers several contradictory explanations of who Jack the Ripper was.
- An issue of Doctor Strange had it that he was possessed by a servant of the Dimension Lord Dormammu.

- Issue #100 of Marvel Comics Master of Kung Fu (1981) featured a story titled "Red of Fang and Claw, All Love Lost". In it, the Ripper was an experiment of Fu Manchu's, who escaped and hid in London. The hero fought him at the end of the story.
- In the Strangers in Paradise arc "Molly & Pooh", a pair of high society killers believe they've discovered the identity of the Ripper and dispatch him in his old age. This story has virtually nothing to do with the rest of the series, and never connects back with it in any appreciable way.

Later still, the origin of the knife turns out to be even darker than that, as the "knife" is actually the remains of Lucifer's sword that broke when he fell from Heaven, and Malus has given it to any number of profoundly evil people to wield over the years.
- In The Strange Talent of Luther Strode, Jack The Ripper was a devotee of the Hercules Method. "Was" not because he died, but was ritually bound and trapped in a very small box. He get lets out.

Paige cries out in horror at this, while Jason comments to himself: "Didn't Jack The Ripper study biology?"
- Sherlock Homes Vs Jack The Ripper: Complete with werewolves and a zombified Albert Einstein.
- Ultimate Sleepwalker: The New Dreams depicts Jack the Ripper as the illegitimate son of an Italian count who fled to Great Britain and conceived Jack through an affair with a prostitute. The embittered Jack grew up hating his lowborn origins and the mistreatment he received from his family, and studied the occult. A Deal with the Devil turned him into a malevolent supernatural demon that possessed different people and compelled them to commit the murders, which explains why the police never managed to catch him. It's only after Sleepwalker confronts and imprisons Jack in the Mindscape that the murders finally stop.
- Profesor Layton Vs Jack The Raper has the killer resurrected into present day, and the mystery is pursued by Professor Layton, as well as crossed over Death Note characters, and King Shakespeer, not to mention Jams Bound. With Rouge Angles of Satin and a romantic subplot along the way. Almost certainly inspired by the before mentioned Sherlock Homes Vs Jack The Ripper.
- In Say It Thrice, Sanduleak is revealed to have been the Ripper in life. And, ironically, met his end when one of his would-be victims managed to turn the tables on him.

- Bloch later wrote another story about Jack the Ripper, titled "A Toy for Juliette". Harlan Ellison wrote a sequel to that story, "The Prowler in the City at the End of the World". Both stories were first printed in the Dangerous Visions anthology.
- Bloch also wrote two novels about the Ripper: The Will to Kill (1954) and Night of the Ripper (1984).
- There is an entire cottage industry built around non-fiction "true crime" books identifying the Ripper. Over 200 such books have been published, and most of them identify wildly different people as the Ripper.
- One of the more notable was The Diary of Jack the Ripper, supposedly written by one James Maybrick, a middle-class merchant type, and later 'discovered' under some floorboards in the early 1990s. Now largely discredited, it nevertheless caused a huge sensation at the time. (Although Maybrick was a real person, as it happens, who may have been picked for the hoax as he was the victim in another mysterious and controversial Victorian murder case, when his wife Florence was convicted of poisoning him: the prosecution evidence for murder as opposed to suicide or accident was weak and it was believed by her supporters that she had been convicted solely because of her admitted adultery.)
- Jack turns up as the Big Bad of Alex Grecian's Scotland Yard Murder Squad series from the third book onwards. In the series, his crimes stopped because he was captured by the Karstphanomen, a vigilante cult dedicated to catching vicious criminals and making them suffer what their victims did. When he's accidentally freed after years of this torture, he becomes even more ruthless than before.
- In Shadowrun: Streets of Blood, the main characters encounter a crazed serial killer who is actually a clone of Jack the Ripper. Over the course of the story the characters solve the mystery of who the original ripper was.
- That's what the antagonists want them to think. In reality, the Killer's psychosis was the result of severe conditioning. And the people who cloned him had no idea who the real Ripper was, they just cloned the person that would fit into their schemes to discredit the monarchy.
- Also referenced in the Shadowrun short story "Whitechapel Rose", whose eccentric decker protagonist patterns his online persona on Jack the Ripper.
- Bertolt Brecht's Author Tract Threepenny Novel identifies the Villain Protagonist Macheath with Jack the Ripper.

- Terry Moore's Molly and Poo short stories feature the Ripper.
- A Study in Terror (see above) had a novelisation by Ellery Queen that included Ellery himself as a character in the framing story.
- Many novels have Sherlock Holmes going up against the Ripper mystery. One, Michael Dibdin's The Last Sherlock Holmes Story, is notable for the Ripper being Holmes himself, when he's subsumed by his alternate personality, Professor Moriarty.
- One of Boris Akunin's Erast Fandorin detective stories is about the titular nineteenth century sleuth catching Jack the Ripper. This particular version of Jack the Ripper is a Russian who came to Britain and then left back home (he's caught in Moscow).
- The Michael Slade novel Ripper describes a series of occult-themed murders in 1990s Vancouver (investigated by Slade's fictional elite task force Special X) which are revealed over the course of the novel to be directly inspired by/copied from the Ripper murders by way of Aleister Crowley (!), thus advancing an occult-motivated theory of the original crimes (and postulating an identity for the Ripper himself).
- Note that it doesn't conclusively state who the Ripper was, only who Crowley's followers and the novel's own killers think he was. The "Ripper's Trunk" could've been yet another example of Crowley's theatrics.
- Anno Dracula by Kim Newman follows the investigation of the Ripper murders in an alternate history where Count Dracula married Queen Victoria and became ruler of England.
- The Warhammer spin-off novel Beasts in Velvet by Jack Yeovil (actually Kim Newman again) features the Warhammer universe's version of the Ripper murders, investigated by the Warhammer universe's version of Dirty Harry. (It's better than it sounds.)

This creates an Alternate Universe where the Matrix becomes the "Spirit of Jack the Ripper" and exerts a baleful influence over Britain into the 20th century.
- The Haunting of Alaizabel Cray has a character named Stitch-Face. He's a serial killer who has murdered several women, before removing their tongues, eyes and kidneys, and in cases where he's interrupted he kills again shortly after in the same place- although some of the cases are the work of a copycat and part of something darker. Did I mention that this guy aids the protagonist and is ultimately instrumental in stopping the return of the local malevolent evil?
- Jack the Ripper shows up in the 1888 segments of Final Destination: Destination Zero. Turns out he died when Death caused him to be crushed and ground up in the mechanisms of a bridge.
- Paul West's novel The Women of Whitechapel and Jack the Ripper focuses on the Ripper's targets.
- Dacre Stoker's and Ian Holt's Dracula the Un-dead proposes that the Ripper was not just a vampire, but a lesbian vampire—specifically, Countess Elizabeth Bathory, quite undead. In order to do this, they push Jack's spree four years into the future from when it actually happened, which is honestly just the start of how many times the authors fail history class.
- The Peculiar Mating Habits of Wasps is a story in which Watson notices that Sherlock Holmes has no alibi for the nights of the Ripper murders, and begins to suspect foul play. As evidence mounts, Watson finally follows Sherlock only to find out that Holmes has indeed been behind the slayings and the prostitutes had all been approached by the same client: a man infected by an alien creature which was controlling him, using the prostitutes as incubators for its eggs. Holmes had been following it and killing the larvae, explaining the mutilations. The story ends with the whole affair taken care of, with an obligatory title drop.
- The Monstrumologist: Dr. John Kearns is actually the Ripper.
- Neil Gaiman's The Graveyard Book features a self-fulfilling prophecy set in motion by the murder of a family by one of the "Jacks-of-all-trades." While the murders maintain no similarity to the actual Ripper slayings, canonical or apocryphal, the name is a shout out, since in every conversation among them the killers refer to one another as "Jack."
- One of the Jakub Wędrowycz stories shows that the protagonist was Jack the Ripper. He accidentally travelled back in time to the nineteenth-century London, and the key to the time machine fell into a bowl of soup in a house inhabited by Time Police androids masquerading as prostitutes, seconds before dinner time.
- In the Secret Histories series by Simon R. Green, Mr. Stab performed several gruesome human sacrifices in Victorian Whitechapel in order to obtain immortality. It worked, but this form of immortality had consequences for which he was not prepared.
- A central character in the later books of Time Scout.
- Fate/Apocrypha, a spin-off Light Novel of Fate/stay night, features Jack the Ripper as an Assassin-class Servant whose master is a prostitute. Jack the Ripper is also a skimpily-dressed teenaged girl◊* . It's explained she was an wraith, evil spirit born from the resentment of London orphans abandoned by their prostitute mothers.
- Another Fate spin-off, Fate/strange fake, features Jack the Ripper as a Berserker-class Servant. This Jack isn't a person, but rather an incarnation of the Ripper legend itself. Because of this, he has no true form and no idea who the real Jack the Ripper was. He'd like to find out though. Also, he's completely calm and rational despite being summoned as a Berserker...or maybe it's because he was summoned as a Berserker].
- Gordon Korman's kids' trilogy about the Titanic has the Ripper stowing away aboard the ill-fated ship. He dies after the ship sinks.

- Stephen Hunter's I, Ripper, told from the point-of-views of both Jack and the intrepid reporter on his trail, who turns out to be George Bernard Shaw.
- The mystique of the Ripper in fantasy is deconstructed in Roz Kaveney's Rhapsody of Blood Urban Fantasy series. The Ripper turns out to be a rather incompetent and pathetic black magician who is hunted down and executed by one of the heroes as a minor incident in the story, with very little difficulty.
- In the President's Vampire series, it's offhandedly mentioned that Jack was a "starchild" created by Aleister Crowley in the same sort of ritual later used by the Order to create the Boogeyman.
- Star Trek: The Original Series — In the episode "Wolf in the Fold", which postulates that the Ripper was (and is and will be) actually an immortal Energy Being that feeds on the biological signatures of human fear (especially fear from women) called Redjac. Adapted by Robert (Psycho) Bloch from his short story, noted above.
- Kolchak: The Night Stalker — In the original series episode "The Ripper".
- Babylon 5 — In the episode "Comes the Inquisitor", the inquisitor Sebastian is revealed to be Jack the Ripper, cryogenically preserved by the Vorlons and revived when needed. An earlyish hint that the Vorlons might not be as good as they want the younger races to think.
Sebastian: In the pursuit of my holy cause, I... did things. Terrible things. Unspeakable things. The world condemned me... but it didn't matter, because I believed I was right and the world was wrong! I believed I was the divine messenger! I believed I was-Sheridan: Chosen?Sebastian: I was found by the Vorlons. They showed me the terrible depth of my mistake. My crimes. My presumption. I have done four hundred years of penance in their service; a job for which they said I was ideally suited. Now... perhaps... they will finally let me die.Sheridan: I think that might be wise.Sebastian: Good luck to you in your holy cause, Captain Sheridan. May your choices have better results than mine. Remembered not as a messenger, remembered not as a reformer, not as a prophet, not as a hero, not even as Sebastian... Remembered only... as Jack."
- A typo in the script led to Sheridan saying that Jack the Ripper was active in the West End rather than the East End; unfortunately, as the camera was focused on his face at the time, the subsequent dub to have him say East rather than West was extremely obvious.
- The Outer Limits (1995): In the Revival episode "Ripper". Although Jack is never the Ripper, he's just framed for it by the entity due to stumbling upon one of the murders and then trying to unravel the mystery. Double points by having "the Ripper" entity taking over David Warner's character. Warner played Jack the Ripper in Time After Time.
- Special Unit 2 — Jack turns out to be an ogre, but one entirely unlike Shrek.
- Sanctuary — Jack the Ripper is given the name John Druitt (after Montague Druitt, one of the real-life leading suspects for the murders), is the villain of the pilot and Sanctuary head Helen Magnus' former fiancée. He later reappears as an ally, minus the insanity that caused him to murder...Maybe.
- And it was later revealed that the insanity was not, as first thought, caused by brain damage from his teleporting ability, but rather was the result of his body being invaded by a malicious energy creature in a Shout-Out to the above Star Trek episode. His teleportation was what made him vulnerable to the energy creature, so the initial theory wasn't wrong, just incomplete.
- A 2009 ITV drama called Whitechapel has someone re-creating the Ripper murders in 2008 London. More or less, as location filming problems and the changing geography of the city (most of the relevant streets have now gone in slum clearances) has meant some murders have moved location slightly, something noted by the characters. The first episode does have someone stabbed 39 times in line with the Martha Tabram murder (one of the non-canonical ones before the five), but survives when the one aimed for her heart glances off a rib.
- For extra points, many of the characters have very similar names to the real life figures- although the lead detective's first name is changed as it was the same as a serving police officer, which is not allowed.

It emerges that Jack the Ripper was also a time traveller, and simply hid from the police in a different time. His disappearance is explained when he pursues Gary to the 1990s and is promptly run over by a bus.

He is eventually killed in a fire after attempting to attack Natalie in a car.

- The centenary of the murders in 1988 led to the production of a big-budget CBS/Thames Television International Coproduction Mini Series simply titled Jack The Ripper, starring Michael Caine as Abberline. The series aroused some critical hostility for claiming to be highly historically accurate while actually engaging in heavy Very Loosely Based on a True Story. It fingered Sir William Gull for the killer, but dropped the royal-conspiracy elements to show Gull as simply a spontaneous homicidal maniac, with the conspiracy being solely to cover up his actions after he was caught.

The seventh and eighth episodes see the department's medical examiner, Captain Homer Jackson, being framed for a new Ripper murder, but the team are able to prove his innocence.
- The pilot of NBC's Dracula offhandedly mentions that the Ripper was a myth.

- Forever: During an episode featuring a Serial Killer copying various other famous serial killers, including Jack, flashbacks show that Henry was the doctor who examined the bodies of Jack's victims. Likewise, Adam also claims to have been in London at that time, implying that he was the Ripper, though this is never actually confirmed.
- Jack himself never appeared in Friday the 13th: The Series, though a few of his possessions show up as cursed antiques. (A scalpel in "Doctor Jack", and a medical syringe in "Better off Dead")
- On "Grimm" Jack the Ripper's spirit gets to work in modern Portland by possessing Captain Reynard. Turns out all his victims were Wesen prostitutes, leading to him appearing in the Grimm journals...almost a century earlier in Luxembourg. No one knows when or where his first spree was, but given his London accent and tendency to sing creepy Irish folk songs with Killarney changed to Whitechapel, either that was his most recent, he's originally from there, or it's just his favorite.
- The short-lived series The Others had a psychic empath called Mark meet a woman called Mary Jane in their shared dreams, and for the two of them to fall in love over the course of the episode.

- Wynonna Earp: Just before Wynonna sends him back to Hell, the revenant who calls himself Jack of Knives claims that he was the Ripper when he was human. While this is treated with skepticism in-universe, his MO certainly matches that of the other Jack.
- Referenced in Penny Dreadful when Season 1's grisly werewolf killings lead to speculation that the Ripper had resumed his murders. This ends as of Season 2, presumably because the historical Jack, however evil, never committed any crime on the scale of the Mariners' Inn massacre.
- Screaming Lord Sutch's "Jack The Ripper", which has been covered by many other artists, including the Gruesomes, The White Stripes, the Fuzztones, and The Horrors.

- And the domain of Invidia (at least in 2nd Edition) had the Midnight Slasher stalking the streets killing women who was actually female herself.

- Hunter: The Vigil has it that Jack the Ripper stopped killing (in a manner the public would notice) because he became a member of The Ashwood Abbey, who felt they could direct his darker impulses in more constructive directions (or rather, destruction directed towards the supernatural). This proved ineffective, as he repeatedly relapsed into killing innocents, though the Abbey tried to cover it up. They finally decided to do away with him, since even depraved, hedonistic, wealthy thrill-seekers have standards. They gave him the concession of not eating him, something he apparently did.

- The adventure game by Frogwares, Sherlock Holmes Versus Jack the Ripper. Perhaps notable in that the player character collects evidence that positively identifies one (historical) person as the murderer (but he isn't arrested for it since the real killer was never caught). Many genuine suspects questioned by the police of the day are encountered along the way, and the game's designers incorporate real documents, physical evidence, and maps of the area from the actual Whitechapel investigation into the mystery.
The in-game culprit is a vengeful Jewish butcher who'd contracted syphilis from a prostitute and passed it on to his family, leaving one of his sons disfigured. Rather than report him to the police and risk kicking off huge anti-Semitic riots, Holmes arranges for the Jewish community to quietly apprehend the man and keep him imprisoned until the disease finishes him off.
- In World Heroes 2 Jet and Perfect, there's one character simply called "Jack". The game's based around Time Travel, so of course it's the Jack.

Also he glows red and laughs psychotically.

Every so often, someone commits a Jack murder or two and is either killed or detained. The player may investigate this, and eventually discover that Jack is the knives. Knives made in a specific workshop in Polythreme occasionally possess people holding them, turning them into Jacks, at least until they drop the knife. The player is then given the choice of destroying the workshop, ending Jack forever or learning the truth of who created it: The Masters, naturally, as part of a failed experiment that they'd prefer ended but were too lazy to deal with. The player may also (if they pay Fate) temporarily BECOME Jack.

It's also said that the professor who visits him performed autopsies on his female victims, as well as the strong hint that Mandus experimented on him or made him one of his manpigs. However, he's only briefly mentioned, and is practically irrelevant to the story itself.
I am to have a visitor, the distinguished Professor A. He is come to ascertain my mental well-being after my prolonged absence from the club. But I am not stupid. He is here to spy for them. When they stalked The Ripper, he was often called to pontificate upon lacerations and missing organs. And now he comes to me, to doff and wheedle and 'my dear sir' and 'but you must still grieve' and 'perhaps just a quick look at your engines, the triumph of the age'. He knows nothing of loss, nothing of sacrifice. But to refuse? That would simply poke the hornet's nest, invite a swarm of interlopers and thieves. I must entertain this buffoon and submit to his intrusion. Perhaps I should show him the tripery. See whether his stomach, so trained by rummaging in the innards of clumsily vivisected whores, is strong enough to stare into the real engines of his golden age. I may even introduce him to Jack, or his sons at least. We have stronger locks on the windows now, and we bring their toys to them.

- In Van Helsing's route of Code:Realize, Jack the Ripper is identified as a man named Jack Blackman and has been apprehended once, but escaped from custody and set up shop in the sewers, wearing a harlequin mask to hide his face as he stalks and butchers women. Jack was one of the subjects of Hidden Strength, a program which tried to create Super Soldiers by torturing them physically and emotionally until their minds broke and unlocked Power Born of Madness; unfortunately, the process also left them uncontrollably deranged. Jack's insane ramblings suggest that he focuses his homicidal impulses on women he sees as "impure" because his mother abused him when he was a child and Hidden Strength has irrevocably locked him into that trauma.
- Everyman HYBRID gives us the villainous HABIT, an entity capable of Demonic Possession. He boasts a rather long Historical Rap Sheet, which includes being Jack the Ripper. A bit of (perhaps unintended) Fridge Brilliance arises from this: Jack the Ripper was never caught because HABIT possessed a different person for each kill.
