Paul Atreides is a fictional character in the Dune universe created by Frank Herbert. He is a main character in the first two novels in the series, Dune (1965) and Dune Messiah (1969), and returns in Children of Dune (1976). The character is brought back as two different gholas in the Brian Herbert/Kevin J. Anderson novels which conclude the original series, Hunters of Dune (2006) and Sandworms of Dune (2007), and appears in the prequels Paul of Dune (2008) and The Winds of Dune (2009). According to Brian Herbert, Frank Herbert's son and biographer, House Atreides was based on the heroic but ill-fated Greek mythological house of Atreus.

Dune is an American science fiction media franchise that originated with the 1965 novel Dune by Frank Herbert and has continued to add new publications. Dune is frequently described as the best-selling science fiction novel in history. It won the inaugural Nebula Award for Best Novel and the Hugo Award in 1966 and was later adapted into a 1984 film, a 2000 television miniseries, and a two-part film series with the first film in 2021 and a sequel in 2024. Herbert wrote five sequels, the first two of which were concomitantly adapted as a 2003 miniseries. Dune has also inspired tabletop games and a series of video games. Since 2009, the names of planets from the Dune novels have been adopted for the real-world nomenclature of plains and other features on Saturn's moon Titan.
