Jane Toppan (born Honora Kelley; March 31, 1854 – August 17, 1938), nicknamed Jolly Jane, was an American serial killer who is known to have committed twelve murders in Massachusetts between 1895 and 1901; she confessed to a total of thirty-one murders. The killings were carried out in Toppan's capacity as a nurse, targeting patients and their family members. Toppan, who admitted to have committed the murders to satisfy a sexual fetish, was quoted as saying that her ambition was "to have killed more people—helpless people—than any other man or woman who ever lived".
