The Postman is a post-apocalyptic dystopia science fiction novel by David Brin. It is about a man wandering the desolate Oregon countryside who finds a United States Postal Service uniform, which he puts on and then claims he is a mail carrier and federal inspector for the "Restored United States of America". His mail service and claims about the return of a central government gives hope to the people, who are threatened by a murderous, neo-feudalist militia. The first two parts were published separately as "The Postman" (1982) and "Cyclops" (1984). In 1997, a film adaptation of the novel was released starring Kevin Costner and Will Patton.
