The Revenant: A Novel of Revenge is a 2002 novel by American author Michael Punke, based on a series of events in the life of American frontiersman Hugh Glass. The novel was later adapted as a screenplay for a 2015 feature film directed by Alejandro G. Iñárritu. The novel was republished in January 2015 in anticipation of the upcoming film release, but Punke's role as an ambassador to the World Trade Organization (WTO) prevented him from participating in pre-release publicity.
