Alita: Battle Angel is a 2019 American cyberpunk action film based on Yukito Kishiro's manga series Gunnm (or Battle Angel Alita in English). It was directed by Robert Rodriguez, produced by James Cameron and Jon Landau, and written by Cameron and Laeta Kalogridis. Rosa Salazar stars through motion-capture animation as Alita, a cyborg who awakens in a new body without memory of her past and sets out to uncover her destiny. Christoph Waltz, Jennifer Connelly, Mahershala Ali, Ed Skrein, Jackie Earle Haley and Keean Johnson play supporting roles.

Announced in 2003, production was repeatedly delayed due to Cameron's work on Avatar (2009) and its sequels. After years of development hell, Rodriguez was announced as Alita's director in April 2016, with Salazar cast as the lead the following month. Principal photography began in October 2016 in Austin, Texas, mostly at Rodriguez's Troublemaker Studios, and lasted until February 2017.

Alita: Battle Angel had its world premiere at the Odeon Leicester Square in London on January 31, 2019, and was released in the United States on February 14, 2019, by 20th Century Fox. It is the first film produced by Lightstorm Entertainment since Avatar, and the last film released by 20th Century Fox before the acquisition of 21st Century Fox by Disney. The film grossed $405 million worldwide, making it Rodriguez's highest-grossing film, and received mixed reviews from critics, with praise for its action sequences, visual effects, and Salazar's performance, while the screenplay was criticized. A sequel is in development.
