The Warrior of World's End is a 1974 fantasy novel by American writer Lin Carter, set on a decadent far-future Earth in which all the world's land masses have supposedly drifted back together to form a last supercontinent called Gondwane. The book is chronologically the first in Carter's Gondwane Epic. It was first published in paperback by DAW Books, then reprinted twice through November 1978. A trade paperback edition was published by Wildside Press in January 2001. The book includes a map by the author of the portion of Gondwane in which its story is set.
