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

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. The film grossed $405 million worldwide, making it Rodriguez's highest-grossing film, and received mixed reviews from critics. A sequel is in development.
