Barbie is a 2023 fantasy comedy film directed by Greta Gerwig from a screenplay she wrote with Noah Baumbach. Based on the fashion dolls by Mattel, it is the first live-action Barbie film after numerous animated films and specials. Starring Margot Robbie as the title character and Ryan Gosling as Ken, the film follows them on a journey of self-discovery through Barbieland and the real world following an existential crisis. The supporting cast includes America Ferrera, Michael Cera, Kate McKinnon, Issa Rae, Rhea Perlman, and Will Ferrell.

A live-action Barbie film was announced in September 2009 by Universal Pictures with Laurence Mark producing. Development began in April 2014, when Sony Pictures acquired the film rights. Following multiple writer and director changes and the casting of Amy Schumer and later Anne Hathaway as Barbie, the rights were transferred to Warner Bros. Pictures in October 2018. Robbie was cast in 2019, after Gal Gadot turned down the role due to scheduling conflicts, and Gerwig was announced as director and co-writer with Baumbach in 2020. The rest of the cast was announced in early 2022. Principal photography occurred primarily at Warner Bros. Studios, Leavesden, England, and at the Venice Beach Skatepark in Los Angeles from March to July 2022.

Barbie premiered at the Shrine Auditorium in Los Angeles on July 9, 2023, and was released in the United States on July 21. Its concurrent release with Universal Pictures' Oppenheimer was the catalyst of the "Barbenheimer" phenomenon, encouraging audiences to see both films as a double feature. The film grossed $1.446 billion and achieved several milestones, including the highest-grossing film of 2023, the highest-grossing film ever released by Warner Bros., and the 14th-highest-grossing film of all time.

Named one of the top ten films of 2023 by the National Board of Review and the American Film Institute, Barbie received widespread critical acclaim and other accolades, including eight Academy Award nominations (among them Best Picture), winning Best Original Song for "What Was I Made For?"; the song also won the Golden Globe Award for Best Original Song while the film received the inaugural Golden Globe Award for Cinematic and Box Office Achievement.
