Charles Trowbridge Haubiel (born Delta, Ohio, 1892 - died Los Angeles, 1978) was an American composer. He studied in New York City, and spent eight years teaching piano at the Institute of Musical Art in that city before moving on to New York University. His music has been described as a combination of Johannes Brahms and Claude Debussy. He composed three operas in addition to much orchestral and chamber music. His set of variations for orchestra, Karma, won a prize in the 1928 International Columbia Graphophone Competition.
