Rafael Jeroným Kubelík, KBE (29 June 1914 – 11 August 1996) was a Czech-born Swiss conductor and composer.
Son of a well-known violinist, Jan Kubelík, he was trained in Prague, and made his debut with the Czech Philharmonic Orchestra at the age of 19. Having managed to maintain a career in Czechoslovakia under the Nazi occupation, he refused to work under what he considered a "second tyranny" after the Communist Czechoslovak coup d'état of 1948, and took refuge in Britain. He became a Swiss citizen in 1967.
Kubelík was music director of the Chicago Symphony Orchestra (1950–53), musical director of The Royal Opera, Covent Garden (1955–58), and music director of the Bavarian Radio Symphony Orchestra (1961–79), and was a frequent guest conductor for leading orchestras in Europe and America.
As a composer, Kubelík wrote in a neo-romantic idiom. His works include five operas, three symphonies, chamber music, choral works, and songs.
