Eunice Dana Brannan (August 27, 1854 - November 14, 1936) was a feminist activist and a prominent figure in the suffragist movement in New York City.

She played an important role in organizing picketings at the White House in protest of president Woodrow Wilson's refusal to support women's suffrage.

[3] In the 1980s, Brannan traveled to England where she gained an appreciation for the public soapbox form of activism used by women's rights activists in the UK.

[2][1] Brannan was arrested twice for picketing outside the White House in protest of President Woodrow Wilson's opposition to a constitutional amendment allowing women the right to vote.

Her husband, prominent physician Dr. John Winters Brannan, testified at the hearing which influenced the judges decision to pass a not guilty verdict.
