Headfirst into Happiness (German: Kopfüber ins Glück) is a 1931 German comedy film directed by Hans Steinhoff and starring Jenny Jugo, Fritz Schulz and S. Z. Sakall. A separate French-language version Everybody Wins was also produced. Such multiple-language versions were common during the early years of sound before dubbing became more widespread.

It was shot at the Joinville Studios in Paris. The film's sets were designed by the art director Jacques Colombier.
