Gods and Fighting Men - The Story of the Tuatha De Danaan and of the Fianna of Ireland is a collection of tales collated by Lady Augusta Gregory. The book is split into two sections, covering the Irish Mythological Cycle of the Book of Invasions with the coming of the Tuatha De Danaan, whilst the second section details the later hero tales of Finn MacCumhail, the Fenian Cycle.

First published in 1904, Lady Gregory drew upon a number of published and oral sources to create her version, including Eugene O'Curry's Manners and Customs of the Ancient Irish, the Annals of the Four Masters and the Book of Leinster.
