I Lost My Heart in Heidelberg (German: Ich hab' mein Herz in Heidelberg verloren) is a 1952 West German romantic musical film directed by Ernst Neubach and starring Eva Probst, Adrian Hoven and Paul Hörbiger.

[1] The film takes its title from the popular song I Lost My Heart in Heidelberg, whose lyrics Neubach had co-written in the 1920s.

[2] It was part of a strong trend towards heimatfilm productions set in romanticised Southern Germany, Austria or Switzerland.

Although they share the same title, the film is not a remake of I Lost My Heart in Heidelberg from 1926.

It was made at the Spandau Studios in Berlin with location shooting at a variety of places included Cuxhaven, Wiesbaden and Heidelberg itself.
