Anna Elisabeth Söderström CBE (married name Olow; 7 May 1927 – 20 November 2009) was a Swedish soprano who performed both opera and song, and was known as a leading interpreter of the works of Janáček, Rachmaninov and Sibelius. She was particularly well known for her recordings of the lead soprano roles in the three Janáček operas Jenůfa, Káťa Kabanová, and The Makropoulos Affair, all of which received Gramophone Awards. The Gramophone critic John Warrack described her portrayal of Káťa Kabanová as "establishing by an infinity of subtle touches and discreet, sensitive singing the picture of Káta as the richest and most human character in the drama."
Born in , Söderström received her first musical schooling from Adelaide von Skilondz and later studied at the Royal Academy of Music in Stockholm. She made her debut in 1947 at the Drottningholm Palace Theatre singing in one of Mozart's lesser-known works Bastien et Bastienne. From 1949 to 1980 she called the Royal Swedish Opera her home but she frequently appeared at some of the largest opera houses in the world. She was also a regular visitor to the recording studio. Between 1959 and 1964 Söderström was contracted by the Metropolitan Opera in New York City to which she would return in 1983–87. Her last stage performance was in 1999 in Tchaikovsky's The Queen of Spades at the Metropolitan Opera. In 1978 she created the role of Amanda/Clitoria in György Ligeti's Le Grand Macabre at the Royal Swedish Opera.
