The Fantastic Four: First Steps is an upcoming American superhero film based on the Marvel Comics superhero team the Fantastic Four. Produced by Marvel Studios and distributed by Walt Disney Studios Motion Pictures, it is intended to be the 37th film in the Marvel Cinematic Universe (MCU) and the second reboot of the Fantastic Four film series. The film is directed by Matt Shakman from a screenplay by Josh Friedman and Eric Pearson. It features an ensemble cast including Pedro Pascal, Vanessa Kirby, Ebon Moss-Bachrach, and Joseph Quinn as the titular team, alongside John Malkovich, Julia Garner, Paul Walter Hauser, and Ralph Ineson. In the film, the Fantastic Four must protect their 1960s-inspired retro-futuristic world from the planet-devouring cosmic being Galactus (Ineson).

20th Century Fox began work on a new Fantastic Four film following the failure of Fantastic Four (2015). After the studio was acquired by Disney in March 2019, control of the franchise was transferred to Marvel Studios and a new film was announced that July. Jon Watts was set as director in December 2020, but stepped down in April 2022. Shakman replaced him that September when Jeff Kaplan and Ian Springer were working on the script. Casting was underway by early 2023, and Friedman joined to rewrite the script in March, with Cameron Squires and Peter Cameron also writing. The film is differentiated from previous Fantastic Four films by avoiding the team's origin story. Pearson joined to polish the script by mid-February 2024, when the main cast was announced. Filming occurred from July to November 2024 at Pinewood Studios in England, and on location in England and Spain.

The Fantastic Four: First Steps is scheduled to be released in the United States on July 25, 2025, as the first film in Phase Six of the MCU.
