Jussi Björling (5 February 1911 – 9 September 1960) was a Swedish tenor and one of most highly regarded opera singers of the 20th century. Björling was one of the few non-Latin tenors to rival the Italian dominance of the opera world at that time.

Björling was born in Borlänge. He studied singing with his father, David, an accomplished vocalist, and made his debut public appearance at the age of four with the Björling Male Quartet. The group performed in concerts throughout Sweden and the United States for eleven and a half years.

Björling made his professional operatic debut as the Lamplighter in Manon Lescaut at the Royal Swedish Opera in Stockholm in 1930. This was soon followed by Don Ottavio in Mozart's Don Giovanni, Arnoldo in Rossini's William Tell and Almaviva in Rossini's The Barber of Seville. This in turn led to engagements in Europe and the USA. Björling made his American concert debut in Carnegie Hall in 1937; the following year, he made his debut at the Metropolitan Opera as Rodolfo in La bohème.

In December 1940 Arturo Toscanini invited Björling to sing the tenor part in Beethoven's Missa solemnis in New York, a recording of which exists. Björling also performed the Verdi Requiem under Toscanini in 1939 in Lucerne, Switzerland, and in November 1940 in New York, another performance that was recorded and eventually issued as an LP.

In 1945 Björling returned to the US and appeared frequently at the Metropolitan Opera. He sang many major tenor roles in operas in the French and Italian repertoire, including Il trovatore, Rigoletto, Aida, Un ballo in maschera, Cavalleria rusticana, Faust, Roméo et Juliette, La bohème, Madama Butterfly, Tosca and Manon Lescaut. He appeared as Don Carlo in the opening of the 1950–1951 season, but the relationship with Rudolf Bing was strained, and as a consequence he was absent for a couple of seasons in the mid 1950s. Meanwhile, Björling appeared with other American opera companies such as Lyric Opera of Chicago and San Francisco Opera.

Björling appeared at La Scala in 1946 in Rigoletto and 1951 in Un ballo in maschera. His planned Paris début in 1953 was cancelled however, and except for recitals in United Kingdom, some performances in Yugoslavia, East Germany and South Africa in 1954, Björling rarely appeared outside Scandinavia and United States.

On 15 March 1960 Björling suffered a heart attack before a performance of La Bohème at Covent Garden. He insisted on singing in spite of his condition.[6] Björling then made a short American tour, making his last operatic performance as Faust in San Francisco on 1 April 1960 and his final recital at Skansen, Stockholm, on 20 August 1960 (thirty years to the day after his official debut in 1930). He died of cardiomegaly (an enlarged heart) on the island of Siarö [sv], Sweden, on 9 September 1960, aged 49
