Gene Wolfe's "New Urth" series, beginning with Shadow of the Torturer.
Jack Vance's "Dying Earth" series, beginning (not surprisingly) with The Dying Earth. Both of those take place on Earth millions of years in the future; the former is science fiction with a very fantasy-like feel to it, while in the latter magic has risen again (and in fact is the progenitor of D&D's "fire and forget" magic system).
Alternately, Jack Vance "Lyonesse" trilogy, beginning with Suldrun's Garden, takes place immediately before the King Arthur saga (if I remember correctly), and is a more "traditional" fantasy setting.
