Catherine Rosalind Russell (June 4, 1907 – November 28, 1976) was an American actress, model, comedian, screenwriter, and singer, known for her role as fast-talking newspaper reporter Hildy Johnson in the Howard Hawks screwball comedy His Girl Friday (1940), opposite Cary Grant, as well as for her role of catty Sylvia Fowler in George Cukor's The Women (1939), opposite Joan Crawford and Norma Shearer, and for her portrayals of Mame Dennis in the 1956 stage and 1958 film adaptations of Auntie Mame, and Rose in Gypsy (1962). A noted comedienne, she received various accolades, including five Golden Globe Awards and a Tony Award, in addition to nominations for four Academy Awards and a BAFTA Award. Russell has been honored with a Jean Hersholt Humanitarian Award in 1973 and Screen Actors Guild Life Achievement Award in 1975.

In addition to her comedic roles, Russell was known for playing dramatic characters, often wealthy, dignified, and stylish women. She was one of the few actresses of her time to portray women in professional roles such as judges, reporters, and psychiatrists. Russell's career spanned from the 1930s to the 1970s and she attributed this longevity to the fact that, although she had many glamorous roles, she never became a sex symbol.
