The Dune prequel series is a sequence of novel trilogies written by Brian Herbert and Kevin J. Anderson. Set in the Dune universe created by Frank Herbert, the novels take place in various time periods before and in between Herbert's original six novels, which began with 1965's Dune. In 1997, Bantam Books made a $3 million deal with the authors for three Dune prequel novels, partially based upon notes left behind by Frank Herbert, that would come to be known as the Prelude to Dune trilogy. Starting with 1999's Dune: House Atreides, the duo have published 15 Dune prequel novels to date.

Brian Patrick Herbert is an American author who lives in Washington state. He is the elder son of science fiction author Frank Herbert.
