This is a list of Washington (state) suffragists, suffrage groups and others associated with the cause of women's suffrage in Washington.
May Arkwright Hutton was a suffrage leader and labor rights advocate in the early history of the Pacific Northwest of the United States.
Helga Estby was an American suffragist most noted for her walk across the United States during 1896.
Anita Lily Pollitzer was an American photographer and suffragist.
Emma Smith DeVoe was an American women suffragist in the early twentieth century, changing the face of politics for both women and men alike. When she died, the Tacoma News Tribune called her Washington state's "Mother of Women's Suffrage".
Linda Deziah Jennings (1870-1932) was an American women's suffrage activist and cookbook editor, based in Washington state. She was the editor of Washington Women's Cook Book (1908), which was published by the Washington Equal Suffrage Association. The cookbook, which was a charity cookbook, served as a fundraiser for the group and helped to bring the cause of suffrage into Washington homes.
Alice Sampson Presto (1879–?) was a suffragist and the first African-American woman to run for office in the state of Washington.
Lucie Isaacs was an American writer, philanthropist, and pioneer suffragist. As a writer of essays and descriptive articles, she was known to early readers of the Overland magazine and other western periodicals under various pen names, suffering from shyness that made her shrink from publicity. She was a co-organizer of the first woman's club in Walla Walla, Washington, a member of the Oregon Pioneer Association, and a supporter of the arts. Isaacs served as president of Walla Walla's suffrage association, lived to see full suffrage given to women and voted before her death in Walla Walla in November 1916.
The National Council of Women Voters, founded in 1911, was a nonpartisan organization intended to educate women voters and support the suffrage movement. The council was founded by Emma Smith DeVoe. At the 1909 conference of the National American Women's Suffrage Association (NAWSA), DeVoe proposed the formation of a national organization for women in states where they had voting rights. She envisioned this being an organization not only to advocate for women who could vote at the state level, but to eventually succeed NAWSA once suffrage was settled law. The motion was voted down, so DeVoe formed her own coalition. In 1919, a national convention of NCWV and NAWSA voted to merge the two organizations. The merger was made official in early 1920, resulting in the formation of the League of Women Voters.
