Zsuzsi kisasszony (literally "Miss Suzy", also known as Miss Springtime and Die Faschingsfee) is an operetta in 3 acts by Hungarian composer Emmerich Kálmán. It premiered at the Vig theatre in Budapest on February 23, 1915. The Hungarian language libretto was by Martos and M. Bródy. As Miss Springtime, it opened, in heavily revised form, on Broadway in 1916.

With a German libretto by A. M. Willner and R. Oesterreicher, a revised version of the music premiered as Die Faschingsfee (The Carnival Fairy) in Vienna, at the Johann Strauss Theater, on 21 September 1917. A further revision of Die Faschingsfee was done for Berlin, with a larger role for the leading lady, and it is the Berlin version that is most often seen today. In 2012, an English translation of the Berlin version was done at the Ohio Light Opera under the title Miss Springtime, but the recording made of that production was eventually released in 2013 under the title The Carnival Fairy.
