Fantastic Four (stylized as FANT4STIC) is a 2015 superhero film based on the Marvel Comics superhero team of the same name. Directed by Josh Trank, who co-wrote the screenplay with Jeremy Slater and Simon Kinberg, it stars Miles Teller, Michael B. Jordan, Kate Mara, Jamie Bell and Toby Kebbell. The film follows a group of intelligent teenagers that build a transdimensional portal, causing them to gain superhuman abilities.

20th Century Fox announced plans to reboot the franchise, and development of the film began in August 2009. Trank was hired to direct in July 2012 and the principal characters were cast in January 2014. Principal photography began in May 2014 in Baton Rouge, Louisiana and lasted for two months. Dissatisfied with the director's original cut, Fox executives mandated reshoots, which took place in January 2015.

Fantastic Four premiered at Williamsburg Cinemas in New York City on August 4, 2015, and was released on August 7 in the United States. It received mostly negative reviews from critics for its screenplay, direction, acting, lack of humor, visual effects, pacing and unfaithfulness to the source material, although the soundtrack was praised. The film was a box-office bomb, grossing $167.9 million worldwide against a production budget of $120 million. It received several Golden Raspberry Awards, including Worst Director and Worst Picture. Trank also voiced his displeasure with the final film, blaming the studio's interference.

The film was the third and final Fantastic Four film to be distributed by 20th Century Fox, which was acquired by Disney in 2019. A sequel scheduled for release on June 9, 2017 was canceled after the first film's failure. Another reboot, titled The Fantastic Four: First Steps, is scheduled for release on July 25, 2025, as the first film in Phase Six of the Marvel Cinematic Universe.
