This is a list of mass or spree killers in the Americas (excluding the United States).
A mass murderer is typically defined as someone who kills three or more people in one incident, with no "cooling off" period, not including themselves.
[1][2] A mass murder typically occurs in a single location where one or more persons kill several others.
[3][4][5] Specific notable subtypes of mass murder, including politically motivated crimes, workplace killings, school attacks and familicides, have their own lists.
This list does not include serial killers, members of democidal governments, or major political figures who orchestrated such actions.
