The Model Husband (German: Der Mustergatte) is a 1937 German comedy film directed by Wolfgang Liebeneiner and starring Heinz Rühmann, Leny Marenbach, and Hans Söhnker.^[1] It is based on a 1915 American play Fair and Warmer by Avery Hopwood. It was shot at the Johannisthal Studios in Berlin. The film's sets were designed by the art directors Otto Gülstorff and Hans Minzloff. The film was screened at the Venice Film Festival where it won an award. In the 1950s, it was remade twice: a 1956 West German film The Model Husband and a 1959 Swiss The Model Husband.

A London banker makes a business trip to Venice where he falls in love with a woman who thinks her friend is cheating. They marry, but she soon gets bored because he is the "model husband"—the way she wished previously: he barely looks at other women. In turn no woman shows interest in him. Moral of the story: she said she wished for the model husband but unconsciously desires a Don Juan. Once he understands, he acts like one (a little) and she falls in love with him all over again.

The film was censored for youth by the Nazis.
