Dune: Part Two is a 2024 American epic science fiction film directed and co-produced by Denis Villeneuve, who co-wrote the screenplay with Jon Spaihts. The sequel to Dune (2021), it is the second of a two-part adaptation of the 1965 novel Dune by Frank Herbert. It follows Paul Atreides as he unites with the Fremen people of the desert planet Arrakis to wage war against House Harkonnen. Timothée Chalamet, Zendaya, Rebecca Ferguson, Josh Brolin, Stellan Skarsgård, Dave Bautista, Charlotte Rampling, and Javier Bardem reprise their roles from the first film, with Austin Butler, Florence Pugh, Christopher Walken and Léa Seydoux joining the ensemble cast.

Development began after Legendary Entertainment acquired film and television rights for the Dune franchise in 2016. Villeneuve signed on as director in 2017, intending to make a two-part adaptation of the novel due to its complexity. Production contracts were only secured for the first film before the second film was greenlit by Legendary in October 2021, subject to the success of the first. Principal photography took place in Budapest, Italy, Jordan, and Abu Dhabi between July and December 2022.

Delayed from a November 2023 release date due to the 2023 Hollywood labor disputes, the film premiered at the Auditorio Nacional in Mexico City on February 6, 2024, and was released in the United States on March 1, 2024 to critical and audience acclaim and grossed $714.4 million worldwide, setting several records, surpassing its predecessor, and making it the fourth highest-grossing film of 2024. A sequel based on Herbert's 1969 novel Dune Messiah is in development.
