Brenda Diana Duff Frazier (June 9, 1921 – May 3, 1982) was an American socialite popular during the Depression era. Her December 1938 debutante ball was so heavily publicized worldwide, she eventually appeared on the cover of Life magazine for that reason alone. She was known and dubbed as a "Poor Little Rich Girl" by the media, together with socialites and other famous debutantes Barbara Hutton, Gloria Vanderbilt and Doris Duke.
