Frances Dana Barker Gage (October 12, 1808 – November 10, 1884) was a leading American reformer, feminist and abolitionist.

She works closely with Susan B. Anthony and Elizabeth Cady Stanton, along with other leaders of the early women's rights movement in the United States.

She is among the first to champion voting rights for all citizens without regard to race or gender and is a particularly outspoken supporter of giving newly freed African American women the franchise during Reconstruction, along with African American men who had formerly been slaves.
