Nights of Cabiria (Italian: Le notti di Cabiria) is a 1957 drama film co-written and directed by Federico Fellini. It stars Giulietta Masina as Cabiria, a prostitute living in Rome. The cast also features François Périer and Amedeo Nazzari. The film is based on a story by Fellini, who expanded it into a screenplay along with his co-writers Ennio Flaiano, Tullio Pinelli and Pier Paolo Pasolini.

In addition to the best actress award at the Cannes Film Festival for Giulietta Masina, Nights of Cabiria won the 1958 Academy Award for Best Foreign Language Film. This was the second straight year Italy and Fellini won this Academy Award, having previously won for La Strada, which also starred Masina.

In 2008, the film was included on the Italian Ministry of Cultural Heritage’s 100 Italian films to be saved, a list of 100 films that "have changed the collective memory of the country between 1942 and 1978."
