Timothy James McVeigh (April 23, 1968 – June 11, 2001) was an American domestic terrorist convicted and executed for the detonation of an ammonium nitrate and nitromethane fertilizer truck bomb in front of the Alfred P. Murrah Federal Building in Oklahoma City on April 19, 1995. Commonly referred to as the Oklahoma City bombing, the attack killed 168 people and injured over 600. According to the United States government, it was the deadliest act of terrorism within the United States prior to the September 11 attacks, and remains the most significant act of domestic terrorism in United States history.

McVeigh, a Gulf War veteran, sought revenge against the federal government for its handling of the 1993 Waco siege, which ended in the deaths of 76 people exactly two years before the bombing, as well as for the 1992 Ruby Ridge incident. McVeigh hoped to inspire a revolt against the federal government. He was convicted of eleven federal offences and sentenced to death. His execution was carried out in a considerably shorter amount of time than average after his trial, as most convicts on death row in the United States spend an average of fifteen years awaiting execution. Four years after his conviction, McVeigh was executed by lethal injection on June 11, 2001, at the Federal Correctional Complex in Terre Haute, Indiana.
