Hattie McDaniel (June 10, 1893 - October 26, 1952) was an American actress whose portrayal of Mammy in Gone with the Wind (1939) won her the Oscar for Best Supporting Actress, making her the first black person to win an Academy Award.

After working as early as the 1910s as a band vocalist, Hattie McDaniel debuted as a maid in The Golden West (1932). Her maid-mammy characters became steadily more assertive, showing up first in Judge Priest (1934) and becoming pronounced in Alice Adams (1935). In this one, directed by George Stevens and aided and abetted by star Katharine Hepburn, she makes it clear she has little use for her employers' pretentious status seeking. By The Mad Miss Manton (1938) the character she portrays actually tells off her socialite employer Barbara Stanwyck and her snooty friends. This path extends into the greatest role of McDaniel's career, Mammy in Gone with the Wind (1939). Mammy is, in a number of ways, superior to most of the white folk surrounding her.
