Elena Bianchini-Cappelli (1873 – September 19, 1919) was an Italian dramatic soprano opera singer.

[3] The pair also appeared together in Puccini's Manon Lescaut in Cairo in 1895;[4] the two were only given five days to learn the show before opening night, so Caruso fastened the score to Bianchini-Cappelli's back, limiting her stage movement: "I was helpless to do more than hold as still as possible, serving as a human music rack for my comrade," she recalled.

[5] She was in the cast of Verdi's Un ballo in maschera when it was conducted by Arturo Toscanini at Trento.

[6] She first performed in the United States in 1902, the year she sang "Sylvia" in Zanetto at the Metropolitan Opera House, under the direction of composer Pietro Mascagni.

[7] In her forties she taught voice in New York City, endorsed by her old friend Caruso.
