The Bladerunner (also published as The Blade Runner) is a 1974 science fiction novel by Alan E. Nourse, about underground medical services and smuggling.

It was the source for the title, but no major plot elements, of the 1982 film Blade Runner, adapted from the novel Do Androids Dream of Electric Sheep?

The novel's protagonist is Billy Gimp, a man with a club foot who runs "blades" for Doc (Doctor John Long) as part of an illegal black market for medical services.

He suggested "Blade Runner", as preferable to the earlier working titles "Android" and "Dangerous Days", for the Dick adaptation.

[citation needed] Two more of Dick's short stories, "Impostor" and "The Minority Report", were adapted into 2002 films, Impostor and Minority Report, respectively; both films heavily feature underground medical smuggling and procedures among an underclass, as in Nourse's novel, even though these elements are not present in either of the Dick short stories.
