Georgiana Bruce Kirby (7 December 1818 - 27 January 1887) was an American teacher and writer noted for her work in women's suffrage in the late 19th century.
At fourteen, she became a governess to an English family, taking her to Paris and then Melbourne, Canada, where she became a school teacher and taught farming fundamentals.
She returned to London in 1837 and within a year was working for the American Unitarian minister Ezra Stiles Gannett, who brought her to Boston at the age of twenty.
She studied at the school, ran the nursery, and participated in academic discussions with various Brook Farm literary members and visitors, including Ralph Waldo Emerson, William Henry Channing, and Margaret Fuller.
Eliza Farnham had been ridiculed for her plan to bring a large group of single women to California, and eventually decided to travel there alone.
