Long Live the Missus! (traditional Chinese: 太太萬歲; simplified Chinese: 太太万岁; pinyin: Tàitai Wànsuì) is a 1947 Chinese romantic comedy film known as one of the best comedies of the civil war era. The film was directed by Sang Hu (桑弧) with a screenplay written by the famous Chinese literary figure Eileen Chang; the pair also collaborated on the 1947 film Unending Love (Bu Liao Qing, 1947). The film was produced in Shanghai by the Wenhua Film Company. Long Live the Missus! offers a satirical depiction of the lives of women, male-female relationships, and the institution of marriage in 1940s Shanghai.

The film is an example of how the writer Eileen Chang interpreted the Western comedy of manners for Chinese audiences. An English-subtitled version of the film, based on a translation of the filmscript by Christopher Rea, is available on YouTube.
