The 1974 Mitsubishi Heavy Industries bombing (Japanese: 三菱重工爆破事件) was a terrorist bombing of the Mitsubishi Heavy Industries headquarters in Tokyo, Japan on 30 August 1974, killing eight people and injuring at least 376 others. The bombing was committed by the East Asia Anti-Japan Armed Front, a radical far-left anti-Japanese organization, against Mitsubishi Heavy Industries for supplying the United States against North Vietnam during the Vietnam War.

The 1974 Mitsubishi Heavy Industries bombing was the deadliest terrorist attack in Japan until the Tokyo subway sarin attack in 1995.
