Dìdi (Chinese: 弟弟; lit. 'Younger Brother') is a 2024 American coming-of-age comedy drama film, written, directed, and produced by Sean Wang in his directorial debut. The film stars Izaac Wang and Joan Chen. Carlos López Estrada, Josh Peters and Chris Columbus serve as producers and executive producers under their AntiGravity Academy, Spark Features and Maiden Voyage Pictures banners, respectively. The film portrays Chris, a Taiwanese-American eighth grader (Wang) at the dawn of social media. Chris uses social media as an escape from his underwhelming childhood and overburdened mother (Chen), but the Internet also accentuates his preexisting feelings of Asian self-hatred and personal inadequacy.

Dìdi had its world premiere at the 2024 Sundance Film Festival on January 19, 2024, where it won the Audience Award: U.S. Dramatic and U.S. Dramatic Special Jury Award: Ensemble. It was released in the United States by Focus Features on July 26, 2024.
