Hans Knappertsbusch (12 March 1888 – 25 October 1965) was a German conductor, best known for his performances of the music of Wagner, Bruckner and Richard Strauss.

Knappertsbusch followed the traditional route for an aspiring conductor in Germany in the early 20th century, starting as a musical assistant and progressing to increasingly senior conducting posts. In 1922, at the age of 34, he was appointed general music director of the Bavarian State Opera, holding that post for eleven years. In 1936 the Nazi régime dismissed him. As a freelance he was a frequent guest conductor in Vienna and Bayreuth, where his performances of Parsifal became celebrated.

Studio recording did not suit Knappertsbusch, whose best-known recordings were made live during performances at Bayreuth. He died at the age of 77, following a bad fall the previous year.
