April, April! is a 1935 German comedy film. It is the first feature film directed by Detlef Sierck, who would go on to fame in America under his anglicized name of Douglas Sirk. The film stars Albrecht Schoenhals, Carola Höhn and Erhard Siedel.

The film's title is a German expression used to reveal to someone that they are the butt of an April Fools' Day prank, and translates as "April Fool!".

A Dutch-language version of the film titled 't Was één April was also filmed, with Sierck directing the footage shot in Germany and Jacques van Tol directing the footage shot in Holland. The Dutch version is believed to be lost, no known copies exist.
