Philip J. Lang (17 April 1911, in New York – 22 February 1986, in Branford, Connecticut) was an American musical arranger, orchestrator and composer of band music, as well as a musical educator. He is credited for writing the orchestral arrangements (orchestrations) for over 50 Broadway theatre shows, including many landmark productions, such as Li'l Abner (1956), Hello, Dolly! (1964), Mame (1966), George M (1968), Annie (1977) and 42nd Street (1980). Together with Robert Russell Bennett, he orchestrated the record-breaking productions of Lerner and Loewe's My Fair Lady (1956) and Camelot (1960). Russell Bennett, the dean of musical orchestrators, remarked that the original arrangements Lang had prepared for Annie Get Your Gun (1946), which utilized a modern technique of orchestral scoring, were beautifully done.
