Therese Wiet (15 October 1885 – 24 January 1971) was an Austrian operetta and concert singer whose career was based primarily in Leipzig.

She made her debut at the Stadttheater [de] in Heidelberg as Fiametta in Franz von Suppé's operetta Boccaccio.

[1][2][3][4] It was in Leipzig that Wiet met her future husband, Rudi Gfaller, at the time a tenor singing with the company and later an operetta composer himself.

A critic for Die Weltbühne noted in 1931 that she could have had international stardom had she not remained "riveted" to Leipzig.

The Panorama was destroyed by Allied bombing in 1943, after which the couple retired to their house in the Austrian spa town of Bad Ischl.
