Ne Zha (Chinese: 哪吒之魔童降世; pinyin: Nézhā zhī Mótóng Jiàngshì; lit. 'Birth of the demon child Nezha'), also spelled Nezha, is a 2019 Chinese animated fantasy adventure film directed and written by Yu Yang, credited as Jiaozi. Its animation production is done by the director's own Chengdu Coco Cartoon. Featuring the popular Chinese mythological character Nezha, the plot is loosely based on the classic 16th-century novel Investiture of the Gods, attributed to Xu Zhonglin.

It was released in China exclusively in IMAX and China Film Giant Screen theatres on 13 July 2019, followed by other theatres on 26 July, distributed by Beijing Enlight Pictures. It is the first Chinese-produced animated feature released in IMAX format, and, despite being the debut feature of its director and animation studio, and having no widely known actors in its voice cast, it has been one of the biggest commercial successes in Chinese cinema, setting numerous records for box-office grosses: as of August 2019, the film is the highest-grossing animated film in China, the worldwide highest-grossing non-U.S. animated film, and the second worldwide highest-grossing non-English-language film of all time at the time of its release. With a gross of over $725 million, it was that year's fourth-highest-grossing animated film, and China's all time fourth-highest-grossing film.

It began a North American release on 29 August 2019 in select IMAX 3D theatres, before a nationwide rollout on 6 September. It was selected as the Chinese entry for Best International Feature Film at the 92nd Academy Awards, becoming the first animated film from China to ever do so, but it was ultimately not nominated.

A second film set in the same universe, titled Legend of Deification, was released on 1 October 2020, which is National Day in China.
