Black Widow is an upcoming American superhero film based on the Marvel Comics character of the same name. Produced by Marvel Studios and distributed by Walt Disney Studios Motion Pictures, it is intended to be the twenty-fourth film in the Marvel Cinematic Universe (MCU). The film is directed by Cate Shortland, written by Jac Schaeffer and Ned Benson, and stars Scarlett Johansson as Natasha Romanoff / Black Widow, alongside David Harbour, Florence Pugh, O-T Fagbenle, and Rachel Weisz. Set after the events of Captain America: Civil War (2016), the film sees Romanoff on the run and forced to confront her past.

Development of a Black Widow film began in April 2004 by Lionsgate, with David Hayter attached to write and direct. The project did not move forward and the film rights to the character reverted to Marvel Studios by June 2006. Johansson was cast in the role for several MCU films beginning with Iron Man 2 (2010). Marvel and Johansson expressed interest in a solo film several times over the following years, before Schaeffer and Shortland were hired in 2018. Benson joined and further casting took place in early 2019.
