Fast X is a 2023 American action film directed by Louis Leterrier from a screenplay written by Dan Mazeau and Justin Lin, both of whom also co-wrote the story with Zach Dean. It is the sequel to F9 (2021), the tenth main installment, and the eleventh installment overall in the Fast & Furious franchise. It stars Vin Diesel as Dominic Toretto, alongside Michelle Rodriguez, Tyrese Gibson, Chris "Ludacris" Bridges, John Cena, Nathalie Emmanuel, Jordana Brewster, Sung Kang, Scott Eastwood, Daniela Melchior, Alan Ritchson, Helen Mirren, Brie Larson, Rita Moreno, Jason Statham, Jason Momoa, and Charlize Theron. In the film, Toretto must protect his family from Dante Reyes (Momoa), who pursues revenge for his father's death and the loss of their fortune.

Development on a tenth main Fast & Furious film began by October 2020, with Lin returning to direct. The film's official title was revealed when principal photography began in April 2022. Lin left as director later that month, citing creative differences, though he retained writing and producing credits. Leterrier was then hired as his replacement a week later and performed several uncredited rewrites to the screenplay. Longtime franchise composer Brian Tyler returned to score the film. With an estimated production budget of $378 million, Fast X is the fourth-most expensive film ever made. Filming lasted until that August, taking place in London, Rome, Turin, Lisbon, and Los Angeles.

Fast X premiered in Rome on May 12, 2023, and was released in the United States on May 19, by Universal Pictures. The film received mixed reviews from critics, with praise for its action sequences and Momoa's performance but criticism towards the writing. It grossed $714 million worldwide, becoming the fifth-highest-grossing film of 2023, but failed to break even. A sequel that reportedly serves as the final main installment is in development and is scheduled to be released in 2026.
