Eaters of the Dead: The Manuscript of Ibn Fadlan Relating His Experiences with the Northmen in AD 922 (later republished as The 13th Warrior to correspond with the film adaptation of the novel) is a 1976 novel by Michael Crichton, the fourth novel under his own name and his 14th overall. The story is about a 10th-century Muslim Arab who travels with a group of Vikings to their settlement.

Crichton explains in an appendix that the book was based on two sources. The first three chapters are a retelling of Ahmad ibn Fadlan's personal account of his actual journey north and his experiences with and observations of Varangians. The remainder is a retelling of Beowulf.
