Willi Forst, born Wilhelm Anton Frohs (7 April 1903 – 11 August 1980) was an Austrian actor, screenwriter, film director, film producer and singer.
 As a debonair actor he was a darling of the German-speaking film audiences, as a director, one of the most significant makers of the Viennese period musical melodramas and comedies of the 1930s known as "Wiener Filme".
 From the mid-1930s he also recorded many records, largely of sentimental Viennese songs, for the Odeon Records label owned by Carl Lindström AG.
Viennese Girls (German:Wiener Mädeln) is a 1945 historical musical film directed by Willi Forst and starring Forst, Anton Edthofer and Judith Holzmeister.

 It was the third film in Forst's "Viennese Trilogy" which also included "Operetta" (1940) and "Vienna Blood" (1942).
 The film was finished in 1945, during the closing days of the Second World War.
 This led to severe delays in its release, which eventually took place in 1949 in two separate versions.
 One was released by the Soviet-backed Sovexport in the Eastern Bloc and the other by Forst.
