List of school shootings in the United States by death toll

This article lists school shootings in the United States for which separate articles exist. The entries are organized first by the number of fatalities, and then by the number of injuries and date of occurrence. Incidents listed here occurred at a variety of institutions, including elementary schools, middle schools, high schools, colleges, universities, and trade schools.

School shootings have occurred in the United States since the mid-19th century, although they were relatively uncommon until around the late 20th century. From the 1960s through the 1980s, fatal school shootings occurred infrequently, with most involving one or two victims. Since the 1990s, however, the frequency and lethality of such incidents have increased, coinciding with a broader rise in mass shootings. The Columbine High School massacre of 1999, which resulted in 16 deaths, including the perpetrators, is often cited as a turning point in media coverage and public perception of school shootings. It influenced subsequent security policies and cultural discussions around youth violence.

The deadliest school shooting in US history took place on April 16, 2007, at Virginia Tech in Blacksburg, Virginia, where 33 people, including the perpetrator, were killed and 23 others injured. Other high-fatality incidents include the Sandy Hook Elementary School shooting in 2012 in Newtown, Connecticut, with 28 deaths (including the perpetrator and his mother); the Robb Elementary School shooting in 2022 in Uvalde, Texas, with 22 deaths (including the perpetrator); and the Parkland high school shooting in 2018 in Parkland, Florida, which left 17 dead. These incidents are among the deadliest school shootings in United States history.
