| Micajah and Wiley Harpe | United States | 1797–1803 | 40 | Highwaymen and river pirates known as "Big" and "Little" Harpe, or the Harpe Brothers, who often killed people of all types for the thrill or minor slights without actual monetary gain, even babies. "Big" Harpe bashed his own infant daughter's head against a tree because her crying annoyed him; this was the only murder he claimed to feel sorry about. "Big" Harpe was shot and beheaded in 1799 by people who sought vengeance for the murder of a woman, while "Little" Harpe was arrested when he took fellow outlaw Samuel Mason's head to the authorities and tried to collect a bounty put on him in 1803, but was recognized, tried and hanged in 1804. |
| Samuel Mason | United States Spanish Louisiana | 1797–1803 | 20+ | Highwayman and river pirate sometimes associated with the Harpe Brothers and other outlaws. After being arrested in Louisiana and turned over to American authorities, Mason overpowered his guards and escaped, but was shot in the process.

Cannon died in prison while awaiting trial, under unclear circumstances. |
| Mary Bateman | United Kingdom | 1803–1808 | 1–4 | "The Yorkshire Witch." Leeds career con woman and thief, hanged in 1809 for the arsenic poisoning of a married couple she had been scamming (the husband survived). Suspect in three more deaths. |
| "Red Inn" murderers | French Empire Kingdom of France | 1805–1830 | 1?–50+? | The owners, Pierre and Marie Martin, and a valet, Jean Rochette, were believed at the time to have murdered up to 50 or more travellers that stayed in their inn in Lanarce, Ardèche to rob them, but were tried for only one murder that has been questioned since by historians. All three were guillotined in front of the inn in 1833. |
| Hiroemon (last name unknown) | Tokugawa shogunate | 1806? | 7 | Samurai serial killer from the Edo period who stabbed seven disabled and homeless people to death and seriously injured seven others between January and March in order to hone his spear skills.

| Andreas Bichel | Bavaria | 1806?–1808 | 2–50+ | "The Bavarian Ripper." Invited young women into his house under the pretense of showing them a "magic mirror" where they could see their future husbands. He blindfolded them and bound their hands behind their backs, which he said was necessary for the ritual, and then hit them in the head, stabbed them in the neck and hacked them to pieces with an axe while they were still alive, burying their bodies in the mountains or under the woodshed in his own home. He kept his victims' clothing, which ended up incriminating him. Sentenced to break at the wheel, later changed to decapitation, and executed in 1809. |
| John Brown and Richard Lemon | Van Diemen's Land | 1807–1808 | 5–9 | Bushrangers fugitive of a British penal colony in the Tamar Valley who murdered three soldiers, a fellow fugitive and at least one Aboriginal Tasmanian.

| Anna Maria Zwanziger | Confederation of the Rhine | 1808–1809 | 4 | Housekeeper who poisoned her employers with arsenic and nursed them back to health to gain their favor; three died. Sentenced to beheading in 1811, which she welcomed as the only way to keep herself from poisoning people. |

| John Williams | United Kingdom | 1811 | 7 | Irish sailor who murdered two families and their servants in London's East End by bashing their heads with a hammer and cutting their throats. Hanged himself in prison while awaiting trial. |
| Gesche Gottfried | Bremen Hanover | 1813–1827 | 15 | Believed today to have suffered from Munchausen syndrome by proxy, as she poisoned several of her relatives and friends with arsenic for no apparent reason. Last person publicly executed in Bremen, where she was beheaded in 1831. |
| Konstantin Sazonov [ru] | Russia | 1814–1816 | 6–7 | Servitor at Tsarskoye Selo Lyceum. He killed six or seven people between 1814 and 1816. |
| Juan Severino Mallari | Philippines | 1816–1826 | 57 (as confessed) | Mallari was a Filipino Catholic priest during the Spanish colonial period from Barangay San Nicolas in the town of Magalang, Pampanga. He became the parish priest of Magalang, Pampanga, in 1816 and believed that his mother was hexed (kulam is the local Filipino term), which became his motive for the killings. He believed killing people could cure his mother's ailments. It is possible that around this time, Mallari's peers noticed signs of his mental instability. The Spanish colonial government executed Mallari by hanging. |
| Samuel Green and William Ash | United States British North America | 1817–1821 | 30 | Itinerant burglars, robbers, and counterfeiters, sometimes acting alone and others in association. Green, considered "America's first public enemy number one," was also a rapist and the more violent and prolific killer of the two, while Ash helped him escape from prison multiple times. While serving a sentence for burglary, Green beat a fellow prisoner to death with an iron rod for informing the guards of an upcoming escape plan, and was hanged as a result in 1822. |
| Olga Briscorn | Russia | 1818–1822 | Unknown | Russian landowner who tortured and murdered an unknown number of her serfs. |
| Thomas Jeffrey (or Jeffries) | Australia New South Wales Van Diemen's Land | 1820–1826 | 1–8 | Navy deserter, robber and conman deported to Australia in 1820. He escaped the penal colony with four other convicts in 1825. While on the run, the party broke into a hut and later the Tibbs settlement. Here they killed one man, severely injured another and kidnapped Mrs. Tibbs and her baby. Jeffries himself is known to have murdered the Tibbs infant before likely assaulting Mrs. Tibbs and letting her go. Following this, the escapees retreated to deeper bushland. Jeffries then killed one of the men searching for him, Magnus Bakie. Facing starvation, they killed one of the party members for food before joining up with bushranger gangs. Hanged. |
| Alexander Pearce | Australia | 1822–1823 | 2–5 | Irishman deported in 1819 to Tasmania. He escaped the convict settlement with seven other convicts in 1824 into the Bush. The group was led by Robert Greenhill because he was the only one with a weapon, the axe used to kill members of the party for food when starvation ensued (ironically, in a region abundant with edible plants and other bush tuckers). After the first such murder for survival (unlikely to have been committed by the undersized, weaponless Pearce), 3 of the seven decamped. Pearce escaped being the second of the party murdered for food before one of the remaining three was fatally bitten by a snake. Only Pearce and Greenhill remained. Pearce was the only one left alive to reach the eastern settlements. Pearce was recaptured and sent back to the Macquaire Harbor convict settlement as his claims of murder and cannibalism weren't believed, and escaped soon after with another convict, Thomas Cox. This time Pearce killed and ate his companion in less than ten days, when he surrendered voluntarily to the authorities. It is difficult to justify calling Pearce a serial killer, as he only killed two people on his own and was at most one of Greenhill's accomplices in two earlier survival murders. However, if more than fictional sensationalism to sell newspapers, his reported last words, "Man's flesh is delicious. It tastes far better than fish or pork" suggest he may have become one had he lived. Hanged in 1824. |
| Charles Routley | Van Diemen's Land | 1824–1828 | 6 | Armed robber and duffer who murdered a shopkeeper, a shepherd and four of his own accomplices. At least two victims were also tortured. Hanged in 1830. |
| William Burke and William Hare | United Kingdom | 1828 | 16 | Lured, intoxicated and murdered people to sell their bodies to Dr. Robert Knox, who used them in his anatomy classes at Edinburgh Medical School. Their usual method was compressing the chests of the victims in a process henceforth known as "burking." Hare was given immunity in exchange for testifying against Burke, who was hanged in 1829, while Knox was never prosecuted. Burke's fiancée was also tried, but her implication was found not proven. |
| Jane Scott | United Kingdom | c. 1828 | 1–4 | Hanged for poisoning her mother. Also believed to have poisoned her father, son and niece. |
| Charles Broughton and Matthew McAvoy | Van Diemen's Land | 1830 | 3 | Escapees of Macquaire Harbor who butchered and cannibalized three fellow convicts. Surrendered to authorities after a month and were hanged. |
| Thomas Griffiths Wainewright | United Kingdom | 1830 | 1–4 | Writer and painter believed to have poisoned his sister-in-law to collect life insurance he recently purchased, as well as possibly his uncle, mother-in-law and a friend. Having fled to France, he was arrested upon his return to Britain in 1837, but could not be prosecuted for lack of evidence. Instead, he was tried for and found guilty of an unrelated case of forgery, for which he was exiled to Tasmania, where he died of natural causes in 1847. |
| Rebecca Smith | United Kingdom | 1831–1849 | 8 | Convicted of poisoning her one-month-old baby, Richard. After her conviction, she admitted to having poisoned seven previous children, which resulted in the death sentence being passed despite the jury's recommendation of mercy. Hanged in 1849. |
| John "Rocky" Whelan | Van Diemen's Land New South Wales (alleged) | 1831?–1855 | 5–6 | Irish career criminal deported to Australia in 1829 and to Tasmania in 1853. The day before his execution by hanging in 1855, Whelan confessed to having shot five men in the head to rob them; an unconfirmed report also links him to the "murderous attack" on a woman in New South Wales. |
| John Bishop and Thomas Williams | United Kingdom | 1831 | 3 | Called the "London Burkers." Copycats of Burke and Hare that were active in London. Hanged. |
| Delphine LaLaurie | United States | 1831–1834 | 2–4 | New Orleans socialite who tortured and maimed slaves. Seven chained and mutilated slaves were rescued after a fire broke out in LaLaurie's mansion, of which two died of their injuries shortly after, and three buried skeletons were later discovered on her property (according to witnesses, one had died in an accident). The case caused outrage in Louisiana, but LaLaurie fled to France and was never prosecuted. Died of natural causes between 1842 and 1849. |
| Giorgio Orsolano | Piedmont-Sardinia | 1832–1835 | 3 | "The Hyena of San Giorgio." Raped, butchered and cannibalized three girls aged nine to fourteen, burying their remains in the country or throwing them in a river. Hanged. |
| Hélène Jégado | France | 1833–1851 | 23–36 | Kleptomaniac domestic servant who robbed and poisoned her employers and relatives with arsenic and antimony. She poisoned during two different periods separated by ten years, 1833–1841 and her final spree in 1851. Because the statute of limitations for the first spree had already run out, she was only tried for three murders and three attempts and guillotined in 1852. |
| Pierre François Lacenaire | France | 1834–1835 | 2 | Poet, army defector and thief. Helped by two accomplices, Lacenaire stabbed a former prison cellmate and his mother in Paris and later attacked a bank employee who survived. They intended to rob the victims, but none of the hits produced any money. While in prison for an unrelated offense, one of the accomplices, Victor Avril, blamed Lacenaire for the murders, and Lacenaire reacted by making a detailed confession that ensured both Lacenaire and Avril would be found guilty and executed. Lacenaire's response and his willingness to answer letters and receive visitors in prison, along with the publication of his memoirs, made him a celebrity. The two men were guillotined in 1836. |
| Burnham Poisoners | United Kingdom | 1835 | 3 | A group of three, consisting of two women (Catherine Frary and Frances Billing) and one man (Peter Taylor), plotted to poison their respective spouses. In 1835, they poisoned four people with arsenic in Burnham Market, killing three: Frary's husband Robert, Taylor's wife Mary and a young girl named Harriet Southgate, who was killed to disguise Robert Frary's death as being from natural causes. All three were hanged at Norwich Castle. |
| John Lynch | New South Wales | 1835–1841 | 9–10 | "The Berrima Axe Murderer." Irish convict turned bushranger who killed his victims with a single hatchet blow to the back of the head. His acquittal at a murder trial in 1835, while his two accomplices were hanged, had convinced him that God approved of his crimes. Hanged in 1842. |
| Diogo Alves | Portugal | 1836–1841 | 70+ | Serial killer, who murdered 70 people in Águas Livres Aqueduct between 1836 and his execution in 1841, thus earning the title "Aqueduct Murderer."

| Jonathan Balls | United Kingdom | 1843–1846 | 2–5+ | Believed to have poisoned his invalid wife, four grandchildren and possibly others. No crime investigation took place before Balls' own suicide by arsenic in 1846. |
| Manuel Blanco Romasanta | Spain | 1844–1852 | 9–14 | "The Werewolf of Allariz." While on the run from his first murder (a constable killed over a debt), Romasanta assumed a new identity and offered his services as a mountain guide to women and children, whom he murdered, later selling their clothing (and according to rumor, also making soap made from their body fat). Following his arrest, he confessed to 13 murders, which he claimed were committed involuntarily during his transformation into a wolf as a result of a curse. He was found guilty of nine and sentenced to die by garrote. This was changed to life in prison following a petition by doctors who wished to study him further. He died in jail in 1863. |
| Edward Rulloff | United States | 1844–1870 | 2–7 | Called "The Genius Killer" and "The Man of Two Lives." Medical doctor and philologist who had a parallel career as an armed robber and con man.

## Unconfirmed serial killers

The existence of the following serial killers is dubious or contradicts the accepted historical record:
| Name | Country | Years active | Notes |
| Poison ring | Roman Republic | 331 BC | According to Livy, there is a story that several Roman men died in what was believed to be a plague, until a servant woman revealed that they had been poisoned by a conspiracy of matrons. According to this story, twenty patrician women arrested admitted to preparing concoctions but claimed that they were medicinal; when they drank it themselves to prove it (at their own suggestion), they died immediately. The story states that a total of 170 matrons were arrested. Livy says that "their act was regarded as a prodigy, and suggested madness rather than felonious intent." |
| John Jarman and his wife | England | 12th to 14th century | "The Jarmans of Colnbrook." Claimed to have murdered between 13 and 60 people at the Ostrich Inn of Colnbrook in the Middle Ages. Though the building is real (and still stands), it only dates to the 1500s, and the most famous description of the killers' modus, involving a trapdoor in a bedroom that opened to a boiling pot in the kitchens beneath, is first described in a fiction work, Thomas Deloney's Thomas of Reading (1602). |
| Andrew Christie | Scotland | 1320–1339 | Called "Christie-Cleek." Purported Perth butcher turned road bandit, murderer and cannibal during a severe famine. |
| Bernabe Cabard and Pierre Miquelon | France | 1410–1415 | Barber and baker duo said to have murdered, robbed and butchered 143 men in Paris; Cabard, the barber, slashed the throats of his clients while shaving them and threw their bodies in a subterranean gallery through a trapdoor, where Miquelon took their meat to make pies. Claimed sometimes to be the historical inspiration of Sweeney Todd and his ally Mrs. Lovett, but there is no record of them before Charles Dupressoir's Drames Judiciaires (1849), published three years after Todd's introduction in The String of Pearls. Mary Elliott's The Tell Tale (1824) details a similar story about a Parisian barber and wig-maker executed during the reign of Napoleon I, but they are not mentioned in the works of Joseph Fouché, the Paris police chief at the time. |
| Christman Genipperteinga | Holy Roman Empire | 1568–1581 | Claimed German bandit who was executed for 964 murders, according to a 1581 pamphlet. Possibly inspired by real bandit Peter Niers, who confessed under torture to 544 deaths and was executed in the same year, although similar characters appear in German fairy tales and folk songs from before that time. |
| Sawney Bean's clan | Scotland | 1575–1600 | Claimed cannibal family that robbed, killed and ate travellers in a cave at Bennane Head until their manhunt and execution by James VI. Contemporary documents make no reference to the hundreds of disappearances and murders said to have been carried out by Bean's clan, which was probably inspired by the earlier legend of Christie-Cleek. |
| Simeon Fleischer | Holy Roman Empire | 1581 and before | Supposedly married and murdered women in order to steal their money. Confessed under torture to 19 murders before being executed by being torn apart with red-hot pincers over a three-day period. The only account of the case comes from an unsigned pamphlet of dubious historicity which relates the lives of Fleischer and fellow medieval serial killers Christman Genipperteinga and Peter Niers. |
| Juan Manuel de Solorzano, Count of La Torre Cosío and La Cortina | New Spain | 1640–1641 | Legendary criollo nobleman under the rule of Viceroy Marquis of Cadereyta said to have murdered several men after mistaking them for a political enemy that had also seduced his wife, and later killed himself during his forced reclusion in a convent. His attributed residence in Mexico City was not built until more than a century after his supposed death in 1641. |
| Lavinia Fisher | United States | 1819 and before | Urban legends state that Fisher was the first female serial killer in the United States. She is supposed to have run an inn with her husband, John, where travellers were convinced to stay the night and then murdered while they slept in order to rob them. No evidence that such murders actually took place has been found; the legend of John and Lavinia Fisher appears to have been inspired by two highway robbers of that name who were hanged in 1820 for leading a gang which assaulted and robbed guests at their inn but did not murder them. |
| Annie Palmer | Jamaica | 1827–1831 | Legendary figure who supposedly poisoned three husbands and a number of lovers and tortured slaves to death for sexual pleasure before being killed in a slave uprising in 1831. The story was recorded as historical fact by some writers, but modern research has proved it to be a complete fiction. |
| Don Vincente | Spain | 1834–1836 | Bibliomaniac ex-monk and librarian said to have killed ten men in Barcelona in order to steal unique books and add them to his collection, sentenced for his crimes to die by garrote. The story, first published as an anonymous article in an 1836 Parisian newspaper, was reprinted as a true story in France for a century, while remaining largely unknown in Spain. |
| Matthias Schambacher (or Schaumboch) | United States | 1850–1879 | Tavern owner in the Blue Mountains who local legend claims was long suspected of murdering some of his guests for their money. Allegedly confessed to at least 11 murders before dying from natural causes in 1879. No record of such crimes can be found before 1938, when Maurice Broun compiled local legends about Schambacher while serving as curator of Hawk Mountain Sanctuary. |
| Polly Bartlett | United States | 1868 | Co-proprietor of "Bartlett's Inn," which was a scam she ran with her father Jim to lure businessmen and other white male travelers with valuables, most often gold. They were seduced by Polly into sex, who fed them steaks and whiskey laced with arsenic to kill them, before their valuables were lifted from their person. The father of one victim called the police to the site, who found the bodies buried in the stables after the Bartletts fled. An attempted victim shot Jim and arrested Polly, who was shot and killed in her prison cell by one of the father's employees, who was never charged. The story originated in a 1963 article in Real West magazine and is now generally considered to be a folk tale rather than actual history. |
| Agnus McVee, Jim McVee and Al Riley | Canada | 1875–1885 | Family claimed to have owned a hotel and store on the Cariboo Road of British Columbia during the Cariboo Gold Rush, where they killed miners for their gold and kidnapped women and forced them into sex trafficking against their will until their arrest and death in prison in New Westminster. The story comes from a single source, and there are no records of disappearances in the area at the time of the murders or existing death certificates of the supposed serial killers apprehended. |
| The Managua Ripper | Nicaragua | 1889 | Also called "The Managua Killer." Alleged unidentified serial killer who murdered and mutilated six prostitutes in the periphery of Managua. In 2005, Trevor Marriott proposed that the Managua Killer and Jack the Ripper were one and the same, a merchant sailor that worked on the route between Britain and the Caribbean. |
