Document Z-3 (Italian:Documento Z-3) is a 1942 Italian spy film directed by Alfredo Guarini and starring Isa Miranda, Claudio Gora and Luis Hurtado.

Many critics were not impressed with the film, feeling that Miranda had not recovered the spontaneity of her pre-Hollywood films. This is considered the first movie in which Federico Fellini has worked as a screenwriter.
