Night and Fog is a 1956 French documentary short film. Directed by Alain Resnais, it was made ten years after the liberation of Nazi concentration camps. The title is taken from the Nacht und Nebel program of abductions and disappearances decreed by Nazi Germany.
The documentary features the abandoned grounds of Auschwitz and Majdanek established in occupied Poland while describing the lives of prisoners in the camps. Night and Fog was made in collaboration with scriptwriter Jean Cayrol, a survivor of the Mauthausen-Gusen concentration camp. The music of the soundtrack was composed by Hanns Eisler.
