Kennedy Company, often shortened to Kennedy Co., was an American computer storage company active from 1963 to 1988. Founded by Charles J. Kennedy (1920–1996) and based in the Greater Los Angeles area, the company was one of the largest independent manufacturers of magnetic-tape data drives for mainframe and minicomputer users. Beginning in the late 1970s, the company also manufactured hard disk drives. In 1979, Kennedy was acquired by Allegheny Ludlum, where it continued to operate independently as a subsidiary. In 1987, it was acquired by Shugart Corporation, who promptly sold off Kennedy's assets to Irwin Magnetic Systems.
