List of mass shootings in the United States in 2020

This is a list of shootings in the United States that have occurred in 2020. Shootings are incidents involving multiple victims of firearm-related violence. The precise inclusion criteria are disputed, and there is no broadly accepted definition. 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. The Congressional Research Service narrows that definition, limiting it to "public mass shootings", defined by four or more victims killed, excluding any victims who survive. The Washington Post and Mother Jones use similar definitions, with the latter acknowledging that their definition "is a conservative measure of the problem", as many shootings with fewer fatalities occur. The crowdsourced Mass Shooting Tracker project has the most expansive definition of four or more shot in any incident, including the perpetrator in the victim inclusion criteria. There were 614 mass shootings in 2020 that fit the inclusion criteria of this article, resulting in 446 deaths and 2,515 injuries, for a total of 2,961 victims. Compared to the previous year, there were 180 more incidents. However, according to Statista the number is only 2 for 2020 compared to 10 mass shootings in 2019.
