A. Viola Neblett (March 5, 1842 – April 30, 1897) was an American temperance activist, suffragist, and women's rights pioneer. She was an indefatigable worker for temperance in Greenville, South Carolina, and was the first woman in her state to declare herself unreservedly for woman suffrage over her own signature in the public prints. She was a notable participant in the annual convention of this Association at Atlanta in 1895, and later spent months in Washington, D.C. in the endeavor to secure the enfranchisement of women under the new constitution of South Carolina. In her last days, she planned a bequest to the National American Woman Suffrage Association. In her own town, she founded and endowed the Neblett Free Library, her home becoming Greenville's first library.
