Nico Dostal (full name: Nikolaus Josef Michael Dostal) (27 November 1895–27 October 1981) was an Austrian operetta and film music composer.
Dostal was born in Korneuburg, Lower Austria, and was the nephew of composer Hermann Dostal. He initially studied law at the University of Vienna, but turned to studying music at the Academy for Church Music in Klosterneuburg, and made a name for himself when his Great Mass in D major premiered in Linz in 1913.
After participating in World War I, Dostal worked as the theatre Kapellmeister in Innsbruck, St. Pölten, Vienna, Chernivtsi and Salzburg, before moving to Berlin in 1924, where he turned his hand to secular music. He worked in music publishing and as a freelance arranger for Oscar Straus, Franz Lehár and Robert Stolz, among others.
Whilst working as a Kapellmeister and composer, Dostal wrote the music for the film Kaiserwalzer (The Emperor's Waltz) and enjoyed great success with his first operetta Clivia. This was followed by Die Vielgeliebte (1934) (The Much-Loved), Die Ungarische Hochzeit (1939) (The Hungarian Wedding), and numerous pieces of film music.
