Edith M. Ainge (1873–1948)[1][2] was an American suffragist[3] and a member of the activist group the Silent Sentinels.

Ainge joined the National Woman's Party (NWP) led by Alice Paul to advocate for women's right to vote in the United States, which was established with the ratification of the 19th amendment in 1920.

On November 10, 1917 suffragists Edith Ainge and Eleanor Calnan were two of thirty three arrested after stationing themselves in protest in front of the White House in Washington D.C.[7] The protest was peaceful, and 68 suffragists demonstrated for the passage of the 19th Amendment.

Ainge and Calnan carried a sign that read, “How Long Must Woman Be Denied a Voice in a Government Which is Conscripting Their Sons.” Ainge, and other suffragists were sentenced to 60 days in jail at the Occoquan Workhouse in Lorton, Virginia for obstructing traffic, referred to as "Unlawful Assembly.” Ainge was given solitary confinement, many of those arrested were tortured, and the event has been named the "Night of Terror.

At the Watch Fire Demonstrations, in Lafayette Square, members of the NWP burned copies of President Woodrow Wilson's speeches in urns.
