This is a list of murderers by number of victims. Both serial killers and spree killers are included, but acts of terrorism (such as the September 11th Attacks) and murder-for-hire (contract killings) are excluded. The murders must be reliably referenced to have been committed "with [the murderer's] own hands." Murderers are listed here by the most common consensus figures, where possible. In cases of murder-suicide, the perpetrator is not included in the victim count.

Serial killers by number of victims

A serial killer is a person who murders three or more people, in three or more separate events over a period of time, for primarily psychological reasons. There are gaps of time in between the killings, which may comprise anywhere from a few hours to many years. This list shows serial killers in order of how many victims they had. In many cases, the exact number of victims assigned to a serial killer is not known, and even if that person is convicted of a few, there can be the possibility that he/she killed many more.

The third column in the table states the number of victims that were definitely assigned to that particular serial killer, and thus the table is in order of that figure. The fourth column states the number of other possible victims that the killer could also have murdered. Some of these crimes are yet to be solved, but have been included because they are notorious or clearly the work of a serial killer, despite nobody being caught.
