Anna is a 1951 Italian melodrama film directed by Alberto Lattuada and starring the same trio as Bitter Rice: Silvana Mangano as Anna, the sinner who becomes a nun, Raf Vallone as Andrea, the rich man who loves her, and Vittorio Gassman as Vittorio, the wicked waiter who sets Anna on a dangerous path.

Silvana Mangano's real sister, Patrizia Mangano, acts as Anna's sister in the film. Sophia Loren has a small uncredited role as a nightclub assistant. Future film directors Franco Brusati and Dino Risi co-wrote the script.

The film features the songs "Non Dimenticar" and "El Negro Zumbón", a baião popularised in the US as "Anna" and recorded much later by Pink Martini.
