"Deadline" is a 1944 science fiction short story by American writer Cleve Cartmill, first published in Astounding Science Fiction. The story described the then-secret atomic bomb in some detail. At that time the bomb was still under development and top secret, which prompted a visit by the FBI.

In 1943, Cartmill suggested to John W. Campbell, the then-editor of Astounding, that he could write a story about a futuristic super-bomb. Campbell liked the idea and supplied Cartmill with considerable background information gleaned from unclassified scientific journals, on the use of Uranium-235 to make a nuclear fission device. The resulting story appeared in an issue of Astounding, released in February 1944 but dated March of that year.
