Yvonne Kenny AM (born 25 November 1950) is an Australian soprano, particularly associated with Handel and Mozart roles. Born in Sydney, she first studied at the University of Sydney in science, hoping to become a biochemist, but decided to pursue a career in music instead. She studied first with Myra Lambert at the Sydney Conservatorium of Music, and later won a scholarship to study at the opera school at La Scala in Milan. After a year of study there she went to England, where after a few recitals and TV appearances, her breakthrough came on 11 October 1975, when she replaced, with only four days' notice, the soprano scheduled to sing in an Opera Rara concert performance of Donizetti's Rosmonda d'Inghilterra at the Queen Elizabeth Hall. It was a triumph and the virtually unknown Kenny became an overnight star.
