Memoirs of a Geisha is a 2005 American epic period drama film directed by Rob Marshall and adapted by Robin Swicord from the 1997 novel of the same name by Arthur Golden. It tells the story of a young Japanese girl, Chiyo Sakamoto, who is sold by her impoverished family to a geisha house (okiya) to support them by training as and eventually becoming a geisha under the pseudonym "Sayuri Nitta." The film centers around the sacrifices and hardship faced by pre-World War II geisha, and the challenges posed to geisha society by the war and a modernizing world. It stars Zhang Ziyi in the lead role, with Ken Watanabe, Gong Li, Michelle Yeoh, Youki Kudoh, Suzuka Ohgo, and Samantha Futerman.

The film was produced by Steven Spielberg (through production companies Amblin Entertainment and DreamWorks Pictures) and Douglas Wick (through Red Wagon Entertainment). Production was split between southern and northern California and a number of locations in Kyoto, including the Kiyomizu temple and the Fushimi Inari shrine. It was released as a limited release in the United States on December 9, 2005, and a wide release on December 23, 2005, by Sony Pictures Releasing (through Columbia Pictures).

The film garnered polarized reviews from critics worldwide and was moderately successful at the box office. It was also nominated for and won numerous awards, including nominations for six Academy Awards, and eventually won three: Best Cinematography, Best Art Direction and Best Costume Design. Zhang was also nominated the Golden Globe Award for Best Actress. The acting, visuals, sets, costumes, and the musical score (composed by Spielberg's long-time collaborator John Williams) were praised, but the film was criticized for casting some non-Japanese actresses as Japanese women and for its style over substance approach. The Japanese release of the film was titled Sayuri, the titular character's geisha name.
