This is a list of mass or spree killers in the United States. A mass murderer is typically defined as someone who kills four or more people in one incident, with no "cooling off" period, not including themselves. A mass murder typically occurs in a single location where one or more persons kill several others.
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.

"2 BLAMED IN BOMBING AS DEATHS RISE TO 10— Tape Recordings at Scene Point to Pair; Sect Leader a Victim", Los Angeles Times, December 11, 1958, p. 1The Los Angeles Times reported on Dec. 11, 1958: The two ex-cultists were linked to the blast by bizarre tape recordings in which they vowed "to bring Krishna to justice". Ten people died in the explosion including Krishna Venta, Cardinal Gene, the two bombers, a seven-year-old girl and an eleven-month-old infant. Venta was identified by his dental plate. After waiting for his resurrection, Sister Ruth eventually had Venta buried at Valhalla Memorial Park, in North Hollywood. The Fountain of the World Monastery in a wooded canyon near Chatsworth was ripped apart early yesterday by a heavy explosion which instantly killed the bearded leader of the cult, Krishna Venta, and seven of his followers. The explosion blew the roof from an adjoining dormitory for children and touched off a brush fire that swept over 150 acres. The fire completed the destruction of the monastery and dormitory.
