{{Map of United States mass shootings}}
This is a '''list of the most notable [[mass shootings in the United States]]''' that have occurred since 1920. [[Mass shooting]]s are incidents involving several victims of firearm-related violence. The precise inclusion criteria are disputed, and there is no broadly accepted definition.<ref>{{Cite web|url=https://www.washingtonpost.com/news/the-fix/wp/2017/10/04/the-squishy-definition-of-mass-shooting-complicates-media-coverage/|title=The vague definition of 'mass shooting' complicates media coverage|last=Borchers|first=Callum|date=October 4, 2017|website=Washington Post|language=en|access-date=August 26, 2018|quote=...'mass shooting' is a term without a universally-accepted definition.}}</ref><ref name=":02">{{Cite web|url=https://fas.org/sgp/crs/misc/R43004.pdf|title=Public Mass Shootings in the United States|last=Bjelopera|first=Jerome|date=March 18, 2013|website=Congressional Research Service|archive-url=https://web.archive.org/web/20130909213006/http://www.fas.org/sgp/crs/misc/R43004.pdf|archive-date=September 9, 2013 |url-status=dead|access-date=August 26, 2018 |quote=There is no broadly agreed-to, specific conceptualization of this issue, so this report uses its own definition for public mass shootings.}}</ref>
