Forever Peace is a 1997 Hugo Award winning science fiction novel by Joe Haldeman.

Though its title is similar to The Forever War and both novels deal with soldiers in the future, Forever Peace takes place on Earth much closer to the present day. Rather than extraterrestrials, the narrator and his fellow soldiers are fighting third world guerrillas in an endless series of economically driven wars. Rather than fighting in person, the American troops use mecha (called "soldierboys", "flyboys" and "waterboys") and are thus nearly invincible. Only the nations that possess molecular nanotechnology are able to build such mecha. These nations form the first world. The novel explores the moral questions raised by such use of military technology, and imagines an unusual approach to ending war permanently.
