The Centennial Olympic Park bombing was a domestic terrorist pipe bombing attack on Centennial Olympic Park in Atlanta, Georgia, on Saturday, July 27, 1996, during the Summer Olympics. The blast directly killed one person and injured 111 others; another person later died of a heart attack. It was the first of four bombings committed by Eric Rudolph in a terrorism campaign against what he called "the ideals of global socialism" and against "abortion on demand". Security guard Richard Jewell discovered the bomb before detonation, notified Georgia Bureau of Investigation officers, and began clearing spectators out of the park along with other security guards.

Domestic terrorism or homegrown terrorism is a form of terrorism in which victims "within a country are targeted by a perpetrator with the same citizenship" as the victims. There are various different definitions of terrorism, with no universal agreement about it.
