Below is a list of fictional planets named in the novels of the Dune universe created by Frank Herbert. In the Appendix of Dune (1965), Herbert notes that there are over 13,300 worlds under Landsraad influence immediately after the Butlerian Jihad. The desert planet Arrakis is the primary planet featured in the Dune series of novels; it is the only known source of the all-important spice melange in the universe. Other notable planets introduced in the originating novel Dune are Caladan (ancestral home of House Atreides) and Giedi Prime (homeworld of House Harkonnen).

Since 2009, the names of planets from the Dune novels have been adopted for the real-world nomenclature of plains (planitiae) and complexes of valleys (labyrinthi) on Saturn's moon Titan. Planet names used to date include Arrakis, Caladan and Kaitain.

III Delta Kaising is one of two planets on which shigawire is grown (the other being Salusa Secundus).

In Dune Messiah, it is said that Tibana, an "apologist for Socratic Christianity" who lived "between the eighth and ninth centuries before Corrino, likely in the second reign of Dalamak", was a native of IV Anbus. Tibana famously said "The hearts of all men dwell in the same wilderness."

Al Dhanab is an "artificial world," location of a Bene Gesserit creche and "one of the original Sisterhood safe planets." A "planet of constant testing," it is considered "an equivalent of Salusa Secundus" and in some ways "worse than Dune." The environment is characterized by "high cliffs and dry gorges, hot winds and frigid winds, little moisture and too much." At some point the Sisterhood considers converting the whole planet into a no-chamber, but ultimately abandons the plan due to the prohibitive energy requirements. In the real world, Al Dhanab is the traditional star name for Gamma Gruis.
