Rosetta Dewart Brice (August 4, 1888 – February 15, 1935), known professionally as Betty Brice, was an American actress in many silent films.

Rosetta Dewart Brice was born in Sunbury, Pennsylvania,^[1] the daughter of Edward Lincoln Brice and Bessie S. Dewart Brice. Her maternal grandfather was William Lewis Dewart, a congressman from Pennsylvania.^[2] Her grandmother and great-grandmother were both also named "Rosetta".^[3] She was raised in Washington, D.C.^[4]

After some time on the stage with stock companies, Brice began acting in silent films, under contract to the Lubin studio in Philadelphia. "I daresay I never will fail to feel that little thrill that comes when I see myself on the screen," she told an interviewer in 1915.^[4]

Films featuring Brice, many of them short films and serials that highlighted Brice's athleticism in stunts, riding, and swimming scenes, included Michael Strogoff (1914),^[5][6] The Fortune Hunter (1914),^[7] The Road o' Strife (1915),^[8] The Sporting Duchess (1915),^[9] The Phantom Happiness (1915),^[10] The Rights of Man: A Story of War's Red Blotch (1915),^[11] The Meddlesome Darling (1915), A Man's Making (1915),^[12] The Gods of Fate (1916),^[12] Her Bleeding Heart (1916), Love's Toll (1916),^[13] Loyalty (1917),^[14] Humility (1918),^[15] and Beau Brummel (1924).^[16]

Brice was engaged to Horace Carpentier Hurlbutt in 1908,^[17] but when he objected to her acting career she broke the engagement. She soon married editor John Oliver La Gorce instead; they had a son, Gilbert Grosvenor La Gorce, before they divorced in 1913.^[18] She married director and actor Jack Pratt as her second husband. She died in 1935 at age 46 from heart disease, in Van Nuys, California.^[4][19]
