Frank Herbert's Dune is a 2000 science fiction television miniseries, based on the 1965 novel of the same title by Frank Herbert. It is written for the screen and directed by John Harrison, and stars Alec Newman as Paul Atreides, William Hurt as Duke Leto Atreides, and Saskia Reeves as Lady Jessica, along with Ian McNeice, Julie Cox, and Giancarlo Giannini. It was an international co-production between the American cable network Syfy, and companies in Germany, Canada, and Italy. This is the second overall filmed adaptation of Herbert’s novel, following the 1984 film directed by David Lynch, and preceding Denis Villeneuve’s two-part film adaptation (2021 and 2024).

The series was first broadcast in three installments, beginning on December 3, 2000. It was released on DVD in 2001 by Artisan Entertainment, with an extended director's cut appearing in 2002. It received generally positive reviews, and was praised by both critics and audiences for its faithfulness to Herbert’s novel. The series was nominated for three Primetime Emmy Awards and won two, for Primetime Emmy Award for Outstanding Cinematography for a Limited Series or Movie and Primetime Emmy Award for Outstanding Special Visual Effects.

A 2003 sequel miniseries titled Frank Herbert's Children of Dune continues the story, adapting the second and third novels in the series (1969's Dune Messiah and its 1976 sequel Children of Dune). Both miniseries are among the highest-rated programs ever to be broadcast on the Syfy Channel.
