Leopold Fall (2 February 1873 – 16 September 1925) was an Austrian Kapellmeister and composer of operettas.

Born in Olmütz (Olomouc), Leo (or Leopold) Fall was taught by his father Moritz Fall (1848–1922), a bandmaster and composer, who settled in Berlin. The younger Fall studied at the Vienna Conservatory before rejoining his father in Berlin. His teachers in Vienna were Robert Fuchs and Johann Nepomuk Fuchs. In 1895 he began a new career as an operetta conductor in Hamburg, and started to compose. From 1904 onwards he devoted himself to composition. While less successful than his contemporary Franz Lehár, he was nevertheless capable of producing melodious and well orchestrated work. After working in Berlin, Hamburg and Cologne he settled in Vienna in 1906, where he died. He is buried at the Vienna Central Cemetery.

His brothers Siegfried [de] and Richard were also composers; both were murdered in the Nazi concentration camps.

His best known operettas in the English-speaking world are The Dollar Princess and Madame Pompadour, which had successful runs in London and New York and remained in the repertory in Germany and Austria throughout the 20th century. Der liebe Augustin [de] (1912; Princess Caprice in London) is reported to have been given an unprecedented 3,360 performances.

Fall wrote incidental music to numerous plays, and three unsuccessful operas; he is mainly known as a composer of operettas in the Silver Age of Vienna operetta.^[1][2][3]
