World War Z: An Oral History of the Zombie War is a 2006 post-apocalyptic horror novel. Rather than a grand overview or single narrative, World War Z is a collection of individual accounts in the form of interviews with characters conducted by the author. The interviews chart a decade-long war against zombies from the view point of many different people of various nationalities. The personal accounts also describe the changing religious, geo-political, and environmental aftermath of the Zombie War.

World War Z was inspired by The Good War, an oral history of World War II by Studs Terkel; and by the zombie films of director George Romero. Brooks used World War Z to comment on social issues like government ineptitude and American isolationism, while also examining themes of survivalism and uncertainty. Critics have praised the novel for reinventing the zombie genre; the audiobook version, performed by a full cast including Alan Alda and John Turturro, won a Audie Award in 2007. A film based upon the book is in development, produced by Plan B Entertainment, directed by Marc Forster and with a screenplay by J. Michael Straczynski.
