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, Valerie Bush 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 regularly uses social media to escape from his underwhelming childhood and overburdened mother (Chen), but the Internet also accentuates his preexisting feelings of internalized racism 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. It received positive reviews and was named one of the top 10 independent films of 2024 by the National Board of Review.
