Dame Eva Turner DBE (10 March 1892 – 16 June 1990) was an English dramatic soprano with an international reputation. Her strong, steady and well-trained voice was renowned for its clarion power in Italian and German operatic roles.

Eva Turner was born in Werneth, Oldham, Lancashire, England. Her first formal singing lessons were with Dan Rootham, the teacher of the famous contralto Clara Butt. From 1911 to 1914 she studied at the Royal Academy of Music in London.

She began her career as a chorister with the Carl Rosa Opera Company and steadily took on larger roles such as Kate Pinkerton and the lead role of Cio Cio San in Madama Butterfly, Micaela in Carmen, Musetta in Puccini's La bohème, Santuzza in Cavalleria rusticana, Elisabeth in Tannhäuser, Freia in Das Rheingold, Elsa in Lohengrin, Brünnhilde in Der Ring des Nibelungen, Leonora in La forza del destino, Leonora in Fidelio, Eva in Die Meistersinger, and the title roles in Aida, Tosca and Thaïs.

In 1924 after an audition for the La Scala company in Milan, she was engaged by its principal conductor Arturo Toscanini as Freia and Sieglinde for the La Scala Ring Cycle of 1924–25.
