The Marriage Swindler (German: Heiratsschwindler) is a 1938 German drama film directed by Herbert Selpin and starring Eduard von Winterstein, Viktoria von Ballasko and Kurt Waitzmann.

It is sometimes known by the alternative title Die rote Mütze (The Red Cap).

[1] The film's sets were designed by the art directors Max Knaake and Karl Vollbrecht.

A confidence trickster is released from prison and travels to a village where he blackmails and tricks women out of their savings, before eventually being caught.

Its neorealism and pessimistic tone were a sharp change from Selpin's recent work which had been dominated by musicals, comedies and society dramas and was extremely rare in the Nazi era when German cinema strove to be light and entertaining.
