Morton Stevens (January 30, 1929 – November 11, 1991) was an American film score composer. In 1965, he became director of music for CBS West Coast operations. He is probably best known for composing the theme music for Hawaii Five-O, a CBS television series for which he won two Emmy Awards in 1970 and 1974. Stevens was taught by Oscar-winning composer Jerry Goldsmith, with whom he frequently collaborated on other projects.
