Mitzi or Mitzy (sometimes Mitzie) is a feminine given name of German origin. Originally a nickname for girls named Maria in German-speaking populations, Mitzi became a given name in its own right, even outside of Germany. Several early-20th-century American actresses chose it as part of their stage name, for example Mitzi Green and Mitzi Gaynor, increasing its popularity. In the United States, Mitzi first appeared on the Social Security Administration's list of the top 1,000 most popular names for baby girls in 1930, peaked in 1955, and has since fallen out of favor, dropping off the list entirely after 1979.
