The Marriage of Maria Braun (German: Die Ehe der Maria Braun) is a 1979 West German drama film directed by Rainer Werner Fassbinder. The film stars Hanna Schygulla as Maria, whose marriage to the soldier Hermann remains unfulfilled due to World War II and his post-war imprisonment. Maria adapts to the realities of post-war Germany and becomes the wealthy mistress of an industrialist, all that while staying true to her love for Hermann.

The Marriage of Maria Braun was one of the more successful works of Fassbinder and shaped the image of the New German Cinema in foreign countries. It has also been acclaimed by many critics as one of Fassbinder’s most profound accomplishments. It is the first installment of Fassbinder's BRD Trilogy, followed by Lola (1981) and Veronika Voss (1982).
