Ma Rainey's Black Bottom is a 2020 American drama film directed by George C. Wolfe and written by Ruben Santiago-Hudson, based on the 1982 play of the same name by August Wilson. The film stars Viola Davis, Chadwick Boseman, Glynn Turman, Colman Domingo, and Michael Potts. Inspired by the career of Ma Rainey, an influential blues singer and the title character, the film dramatizes a turbulent recording session in 1920s Chicago.

The adaptation eventually moved to Netflix and filming began in Pittsburgh in 2019. Boseman died during post-production in August 2020, making Black Bottom his final film appearance. The film is dedicated to his memory.
