Rouge (Chinese: 胭脂扣; Jyutping: Jin1zi1 kau3) is a 1988 Hong Kong supernatural romantic-drama film, directed by Stanley Kwan and starring Anita Mui and Leslie Cheung.

In 1987 Hong Kong, newspaperman Yuen and his girlfriend Chor are drawn into a doomed 1930s romance when the ghost of courtesan Fleur publishes an advertisement in the newspapers, looking for her lost lover Chan Chen-Pang.

Chan was the playboy son of a wealthy family, but longed to be an actor, met and fell in love with talented, beautiful Fleur in one of Hong Kong's teahouses.

Pragmatic Yuen and Chor become dazzled by the romance of Fleur's story and the ghost's glamorous beauty, but as their search for Chan reveals the truth - that Chan did not die with Fleur, frittered away his inheritance and now lives impoverished as a movie extra - they see the value of their own, honest relationship.

The title refers to a rouge case Chan gave to Fleur, which she returns to the now-elderly, guilt-wracked man, before leaving the living world.
