Therese (Thoma) Vogl (12 November 1845 – 29 September 1921) was a German operatic soprano, the first Wellgunde in Wagner's Das Rheingold, and the first Sieglinde in his Die Walküre.

[1] Her operatic debut at Munich came the following year, in the role of Casilda in a performance of Daniel Auber's La part du diable.

Therese and Heinrich Vogl were among the first performers to play the title parts in Tristan und Isolde, being highly regarded in those roles.

[1] On the basis of these "Ring" performances in London, the influential critic Herman Klein described her voice as being a light dramatic soprano, similar to Christine Nilsson's, with a very clear head register and elegant phrasing and diction.

According to Klein, she was one of the finest artists among the early crop of Wagnerian dramatic sopranos but her and her husband's opportunities to appear at the Bayreuth Festival dried up after they quarreled with the Wagner family.
