Hammer of the Gods (book)

Hammer of the Gods is a book written by music journalist Stephen Davis, published in 1985. It is an unauthorized biography of the English rock band Led Zeppelin. After its release it became a New York Times bestseller paperback, and is hyped by its publisher as being the best-known Led Zeppelin biography. It has been reprinted three times since its first publication and has been released under the alternative title Hammer of the Gods: The Led Zeppelin Saga. The title is derived from a line in "Immigrant Song", a track from the band's third album.

Davis travelled with Led Zeppelin for two weeks at the beginning of the band's 1975 U.S. Tour, while he was a music journalist at Rolling Stone magazine.
