This is a list of mass shootings in the United States that have occurred in 2019. Mass shootings are incidents involving multiple victims of firearm-related violence. The precise inclusion criteria are disputed, and there is no broadly accepted definition.[2][3]

Gun Violence Archive, a nonprofit research group that tracks shootings and their characteristics in the United States, defines a mass shooting as an incident in which four or more people, excluding the perpetrator(s), are shot in o­ne location at roughly the same time.[4] The Congressional Research Service narrows that definition, limiting it to "public mass shootings", and defined by four or more victims killed. It excludes counting wounded survivors.[5]The Washington Post and Mother Jones use similar definitions, with the latter acknowledging that their definition "is a conservative measure of the problem", as shootings with fewer fatalities occur.[6][7] The crowdsourced Mass Shooting Tracker project defines a mass shooting as "an incident where four or more people are shot in a single shooting spree. This may include the gunman himself, or police shootings of civilians around the gunman."[8]

As of December 22, 2019, 423 mass shootings have occurred in 2019 that fit the inclusion criteria of this article. This averages 1.19 mass shootings per day. In these shootings, over 1,604 people were injured and over 466 died, for a total of over 2,070 victims.
