Dune is a seminal science fiction franchise created by Frank Herbert, beginning with his 1965 novel of the same name. The series is set in a distant future where noble houses vie for control of the desert planet Arrakis, the only source of the spice melange, a substance that grants extended life and prescient abilities. The narrative follows Paul Atreides, a young noble who rises to power amid political intrigue and rebellion, ultimately transforming into the messianic figure Muad'Dib. Herbert's series explores themes of politics, religion, and ecology, and has been expanded into multiple sequels, prequels, and adaptations, including films, miniseries, and a forthcoming television series.

The Dune universe has also branched out into various forms of media, including comics, video games, and board games, cementing its status as a cultural touchstone. Notable adaptations include David Lynch's 1984 film, which, despite its mixed reception, garnered a cult following, and Denis Villeneuve's 2021 film, which received critical acclaim and box office success. The franchise's impact is evident in its continued relevance and adaptation, highlighting its complex narrative and rich world-building that resonate with audiences across generations.
