Dennie Moore (December 30, 1902 – February 22, 1978) was an American film and stage actress. In the 1930s, she decided to embark on a film career and in 1935 she arrived to Hollywood and made her screen debut in an uncredited role in the Cary Grant-Katharine Hepburn film, Sylvia Scarlett for RKO Radio Pictures.
She primarily was what is known as a "free-lance actress" and floated between Metro-Goldwyn-Mayer and Warner Bros. Studios. In the course of her film career, she would star in twenty-two films between 1935 and 1951. Some of her film credits include parts in Boy Meets Girl (1938), The Women (1939), Saturday's Children (1940), Dive Bomber (1941), and Anna Lucasta (1949). By the mid-1940s, Moore found herself getting less work in Hollywood, but more parts on the New York stage. In 1951, she made her last screen appearance as Mrs. Bea Gingras in The Model and the Marriage Broker. Moving back to New York City she made one final performance onstage in The Diary of Anne Frank in the role of Mrs. Van Daan. In 1957, she retired from acting altogether, aged 54.
