George Rochberg (July 5, 1918May 29, 2005) was an American composer of contemporary classical music.
 Long a serial composer, Rochberg abandoned the practice following the death of his teenage son in 1964; he claimed this compositional technique had proved inadequate to express his grief and had found it empty of expressive intent.
 By the 1970s, Rochberg's use of tonal passages in his music had invoked controversy among critics and fellow composers.
 A teacher at the University of Pennsylvania until 1983, Rochberg also served as chairman of its music department until 1968 and was named the first Annenberg Professor of the Humanities in 1978.
