Mean Girls is a 2024 American musical teen comedy film directed by Samantha Jayne and Arturo Perez Jr. (in their feature directorial debuts), from a screenplay by Tina Fey. It is based on the Broadway musical of the same name, which in turn was based on Mark Waters's 2004 comedy film, both written by Fey and based on Rosalind Wiseman's 2002 book Queen Bees and Wannabes. It stars Angourie Rice, Reneé Rapp, Auliʻi Cravalho, and Christopher Briney. Fey and Tim Meadows reprise their roles from the original film.

Paramount Pictures announced the film's development in January 2020, with Fey returning to write the screenplay and serve as a producer alongside Lorne Michaels, who produced the 2004 film. Composer Jeff Richmond and lyricist Nell Benjamin returned to rework their songs from the stage musical, while Richmond also composed the film's score. Casting began in December 2022. Principal photography took place in New Jersey between March and April 2023.

Mean Girls premiered in New York City on January 8, 2024, and was theatrically released in the United States by Paramount Pictures on January 12. It has grossed $98 million worldwide and received mixed reviews from critics.
