Maria Arloisia Fein (7 April 1892 – 5 September 1965) was an Austrian actress who became a star of German theatre and film before the rise of the Nazis forced her departure.

[2][3][4][5] Fein studied at the Academy for Music and Performing Arts in Vienna from 1909 to 1911 and made her professional debut at the National Theatre Mannheim, where she rose to play the title role in Hebbel's tragedy, Judith.

[2][6] Fein joined the Vereinigte Bühnen, Breslau for the 1921–1922 season and, between 1924 and 1926, performed at the Theater in der Josefstadt, Vienna, where in 1924 she played Lady Milford in Schiller's Kabale und Liebe.

She began with the brothers Robert and Conrad Wiene in Der Mann im Spiegel and Das Leben ein Traum and went on to appear in mostly melodramas and the occasional comedy over the following several years.

[2] In 1948 Fein toured Switzerland with Heinz Woester in their adaptation of Somerset Maugham's Theatre, and the following year played Clytemnestra to the title role of Maria Becker in Jean Giraudoux's Électre.

[2] In America Fein played Caroline of Brunswick to the Prince Regent of Walter Slezak in Norman Ginsbury’s The First Gentleman, but had left over creative differences by the time the show made its Broadway debut on 25 April 1957.

In 1964 Fein told of her experiences in Berlin theaters prior to 1933 in a twelve episode documentary presented by the German network Norddeutscher Rundfunk.
