Emma Carelli (12 May 1877 in Naples – 17 August 1928 near Rome) was an Italian operatic soprano who was particularly associated with the dramatic soprano roles of the verisimo repertoire and the works of Richard Wagner. After a singing career which lasted almost two decades, she managed the Teatro Costanzi in Rome for almost fifteen years. After studying with her father, Beniamino Carelli, at the Conservatorio San Pietro a Majella, she made her professional debut in 1895 in the title role of Mercadante's La vestale during the centenary celebrations at Altamura and went on to appear in the opera houses of many Italian cities. In 1898 she married the left-wing politician, self-made millionaire, and later impresario, Walter Mocchi.
She sang in several world premieres including: Pietro Floridia's La Colonia libera (1899); Meryem in Cesare Galeotti's Anton (1900) and Rosaura in Mascagni's Le maschere at La Scala in 1901. For several years she also sang in South America, primarily Argentina, as part of a touring troupe organized by her husband. In 1903, she sang the title role in Edoardo Mascheroni's opera Lorenza for its South American premiere in Buenos Aires. She became particularly associated with the title role in Leoncavallo's Zazà and sang in several operas by Richard Wagner, including the roles of Kundry in Parsifal and Elisabeth in Tannhäuser. She also sang the title role in Puccini's Tosca, the title role in Giordano's Fedora, Santuzza in Mascagni's Cavalleria rusticana, and Margherita in Boito's Mefistofele among other roles.
