Logan is a 2017 American superhero film starring Hugh Jackman as the titular character. It is the tenth film in the X-Men film series, the third and final installment in the Wolverine trilogy, following X-Men Origins: Wolverine (2009) and The Wolverine (2013), and a standalone sequel to X-Men: Days of Future Past (2014). The film, which takes inspiration from the "Old Man Logan" comics storyline by Mark Millar and Steve McNiven, follows an aged Wolverine and an extremely ill Charles Xavier who must defend a young mutant named Laura from the Reavers led by Donald Pierce and Zander Rice. The film is produced by 20th Century Fox, Marvel Entertainment, TSG Entertainment and The Donners' Company, and distributed by 20th Century Fox. It is directed by James Mangold, who co-wrote the screenplay with Michael Green and Scott Frank from a story by Mangold. In addition to Jackman, the film also stars Patrick Stewart, Richard E. Grant, Boyd Holbrook, Stephen Merchant, and introduces Dafne Keen in her film debut as Laura.

The film was designed to look like it takes place in the near future, with slight updates to technology and the social environment, and written with a dark and violent tone closer to the Western than the traditional superhero genre. Principal photography began in Louisiana on May 2, 2016, and wrapped on August 13, 2016, in New Mexico. The locations used were mainly in Louisiana, New Mexico, and Mississippi.

It premiered at the 67th Berlin International Film Festival on February 17, 2017, and was theatrically released in the United States on March 3, 2017. The film was praised for its action scenes, emotional depth, performances, and Mangold's direction, becoming the best-reviewed film in the X-Men franchise. It was selected by the National Board of Review as one of the top ten films of 2017, and nominated for Best Adapted Screenplay at the 90th Academy Awards, becoming the first live-action superhero film to be nominated for screenwriting. Grossing $619.2 million worldwide, it became the third-highest-grossing R-rated film at its release. Jackman and Keen reprised their roles in the 2024 film Deadpool & Wolverine.
