Mindkiller is a 1982 science fiction novel by American writer Spider Robinson. The novel, set in the late 1980s (re-edited later to begin in 2006), explores the social implications of technologies to manipulate the brain, beginning with wireheading, the use of electric current to stimulate the pleasure center of the brain in order to achieve a narcotic high. The novel is unusual in its use of point of view, in a fashion similar to that of Robinson's mentor Robert A. Heinlein's novel The Number of the Beast.
