Ellen Gulbranson (née Nordgren) (4 March 1863 – 2 January 1947) was a Swedish operatic soprano with a strong, dramatic voice best suited to the works of Richard Wagner.

Subsequently, she also studied with Marchesi's daughter Blanche, who strengthened Gulbranson's top notes and transformed her voice from that of a mezzo-soprano into that of a dramatic soprano.

Gulbranson made her operatic debut in 1889 as Amneris in Giuseppe Verdi's Aida in Stockholm, and sang the Wagnerian roles of Brünnhilde and Ortrud there in 1898.

In 1896, she made her first appearance at the Bayreuth Festival, then in its 20th year, alternating in the role of Brünnhilde with the veteran diva Lilli Lehmann.
