Sadako and the Thousand Paper Cranes is a children's historical novel written by Canadian-American author Eleanor Coerr and published in 1977. It is based on the story of Sadako Sasaki.

Sadako Sasaki was a Japanese girl who became a victim of the atomic bombings of Hiroshima and Nagasaki by the United States. She was two years of age when the bombs were dropped and was severely irradiated. She survived for another ten years, becoming one of the most widely known hibakusha—a Japanese term meaning "bomb-affected person". She is remembered through the story of the more than one thousand origami cranes she folded before her death. She died at the age of 12 on October 25, 1955, at the Hiroshima Red Cross Hospital.
