"Do Androids Dream of Electric Sheep?" (retitled "Blade Runner: Do Androids Dream of Electric Sheep?" in some later printings) is a science fiction novel by American writer Philip K. Dick, first published in 1968. The novel is set in a post-apocalyptic San Francisco, where Earth's life has been greatly damaged by a nuclear global war, leaving most animal species endangered or extinct.

The main plot follows Rick Deckard, a bounty hunter who is tasked with "retiring" (i.e. killing) six escaped Nexus-6 model androids, while a secondary plot follows John Isidore, a man of sub-par IQ who aids the fugitive androids.

The book served as the primary basis for the 1982 film "Blade Runner", and many elements and themes from it were used in its 2017 sequel "Blade Runner 2049".

As a "bildungsroman of the cybernetic age", Galvan maintains, "Do Androids Dream of Electric Sheep?" follows one person's gradual acceptance of the new reality. Christopher Palmer emphasizes Dick's speech to bring to attention the increasingly dangerous risk of humans becoming "mechanical". "Androids threaten reduction of what makes life valuable, yet promise expansion or redefinition of it, and so do aliens and gods".
