Love and Duty is a 1931 Chinese silent film, directed by Bu Wancang and starring Ruan Lingyu and Jin Yan. Long considered lost, it was accidentally rediscovered in Uruguay in the 1990s, and was almost immediately hailed as one of the greatest Chinese silent films. Like many such films, it has both Chinese and English intertitles.

Ruan Lingyu portrays two different characters in the film: the mother, Yang Nei Fang, and Huang Koon Ying, Nei Fang's daughter. For shared scenes, split screen technology is used to make both characters appear.
