Original Child Bomb is a 2004 documentary about the aftermath of the atomic bombings of Hiroshima and Nagasaki. The film premiered at the 2004 Tribeca Film Festival and was aired on many stations on August 6, 2005, the 60th anniversary of the bombings. The title of the film was inspired by Thomas Merton's poem of the same name, which is quoted throughout the film.

The documentary employs color footage that had previously been labeled top secret by the US government. The 2005 airing of Original Child Bomb was the most extensive exposure to date of this footage in the United States. It had been filmed by both the United States military and Japanese camera crews.

Original Child Bomb was directed by Carey McKenzie and produced by Holly Becker.
