The Columbine High School massacre, often simply referred to as Columbine, was a school shooting and a failed bombing that occurred on April 20, 1999, at Columbine High School in Columbine, Colorado, United States. The perpetrators, twelfth-grade students Eric Harris and Dylan Klebold, murdered twelve students and one teacher. Ten of the twelve students killed were in the school library, where Harris and Klebold subsequently died by suicide. Twenty-one additional people were injured by gunshots, and gunfire was also exchanged with the police. Another three people were injured trying to escape. The Columbine massacre was the deadliest mass shooting at a K-12 school in U.S. history, until December 2012. Columbine is still considered one of the most infamous massacres in the U.S. for inspiring many other school shootings and bombings; the word "Columbine" has since become a byword for modern school shootings. As of 2024, Columbine is still the deadliest school shooting in Colorado and one of the deadliest mass shootings in the United States.

A mass shooting is a violent crime in which one or more attackers kill or injure multiple individuals simultaneously using a firearm. There is no widely accepted definition, and different organizations tracking such incidents use different criteria. Mass shootings are often characterized by the indiscriminate targeting of victims in a non-combat setting, and thus the term generally excludes gang violence, shootouts and warfare. Mass shootings may be done for personal or psychological reasons, but have also been used as a terrorist tactic. The perpetrator of an ongoing mass shooting may be referred to as an active shooter.
