The 355 is a 2022 American action spy thriller film directed by Simon Kinberg from a screenplay by Theresa Rebeck and Kinberg, and a story by Rebeck. The film features an ensemble cast, starring Jessica Chastain, Penélope Cruz, Fan Bingbing, Diane Kruger, and Lupita Nyong'o as a group of international spies who must work together to stop a terrorist organization from starting World War III. Édgar Ramírez and Sebastian Stan also star. The title is derived from Agent 355, the codename of a female spy for the Patriots during the American Revolution.

Chastain proposed the idea for the film while working with Kinberg on Dark Phoenix. The project was officially announced in May 2018, and distribution rights were acquired by Universal Pictures at the 71st Cannes Film Festival. Filming took place in Paris and London from June through September 2019. The 355 was theatrically released in the United States on January 7, 2022. It received generally negative reviews from critics and was a box-office bomb, grossing $27.8 million worldwide against its budget of $40–75 million, resulting in Universal losing an estimated $93 million on the film.
