Margit Angerer (born "Margit Rupp": 1 June 1903 - 31 January 1978) was a Hungarian opera soprano.
Margit Rupp was born in Budapest. She studied at the Fodor Conservatorium and at the Budapest Music Academy where she was taught by Arturo de Sanctis. She made her debut in Budapest. After her marriage to the logistics entrepreneure Gottfried Schenker-Angerer in 1920 and the birth of their daughter Maria in 1922 she relocated to Vienna in 1927. She had already made her Vienna debut the previous year as Donna Leonora in Verdi's La forza del destino. Her debut was the more noteworthy because she was not a product of the mainstream Vienna arts establishment. In 1927 she concluded a contract with the Vienna State Opera where she sustained a successful career till 1935. Abroad, she used the stage-names Margit von Rupp and Margit Schenker-Angerer.
Between 1926 and 1935 she appeared more than 160 times in solo roles at the Vienna Opera. There were also guest appearances elsewhere, notably at the Salzburg Festival where she appeared in 1930, 1933 and 1935 as Octavian in Rosenkavalier. She regularly played Octavian in Vienna, too, and it appears to have been the role for which she was best known. Other frequent stage portrayals included Elsa in Lohengrin and Dorota in Weinberger's Schwanda the Bagpiper.
She made her first appearance in the title role of Gluck's Iphigénie en Aulide at Salzburg in 1930. It was also at Salzburg that in 1933 she appeared as Aithra in Egyptian Helena, a less well known product of the long professional partnership between Richard Strauss and his librettist Hugo von Hofmannsthal. Nor was Argerer entirely unknown to cinema audiences: she featured as "the concert singer" in Gustav Fröhlich's "Rakoczy-Marsch" (1933).
