Supergirl: Woman of Tomorrow is an upcoming American superhero film based on DC Comics featuring the character Supergirl. Produced by DC Studios and to be distributed by Warner Bros. Pictures, it will be the second film in the DC Universe (DCU). The film is directed by Craig Gillespie, written by Ana Nogueira, and stars Milly Alcock as Kara Zor-El / Supergirl, alongside Matthias Schoenaerts, Eve Ridley, David Krumholtz, and Emily Beecham.

A film featuring Supergirl entered development as part of the DC Extended Universe (DCEU) franchise in August 2018, and the character was introduced in the film The Flash (2023), portrayed by Sasha Calle. Plans for the standalone project were altered when James Gunn and Peter Safran became co-CEOs of DC Studios in October 2022. A new Supergirl film was announced in January 2023 as an adaptation of the comic book miniseries Supergirl: Woman of Tomorrow (2021–22) by Tom King and Bilquis Evely. Nogueira was hired by November 2023, Alcock was cast in January 2024, and Gillespie joined in May. Filming is taking place from January to May 2025 at Warner Bros. Studios Leavesden and London in England, and in Iceland.

Supergirl: Woman of Tomorrow is scheduled to be theatrically released in the United States on June 26, 2026. It will be part of the DCU's Chapter One: Gods and Monsters.
