Elizabeth Gertrude Holliday (23 May 1925—3 April 2011), known professionally as Betty Holliday and Betty Holliday Deckoff, was an American visual artist and educator who was active on Long Island, New York, and in New York City.
Her most well-known works are large figurative paintings and drawings.
Her early paintings were dominated by color, as she was trained when Abstract Expressionism was the dominant American art movement; later she became interested in photography and, as a result, experimented in "decolorizing" her paintings and drawings.
