A. Viola Neblett (March 5, 1842 – April 30, 1897) was an American temperance activist, suffragist, and women's rights pioneer.

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.

The abolition of slavery and its enforcement at the close of the Civil War reduced her grandmother, her mother and herself to poverty, and, but for the help of a former slave, they would have suffered for food in 1865.

They made their name in Augusta till autumn 1879, after which time they removed to Greenville, South Carolina, with her mother and his aunt, Susan Turnispeed.

[4] She became an indefatigable Woman's Christian Temperance Union (WCTU) worker, demonstrating executive ability and expending a great amount of her time.

[5] In March 1895, she traveled in South Carolina making appointments for speakers who were to canvass the State in April or May in the interest of the woman's suffrage movement.

[15] Although the woman's suffrage initiative was not passed, Neblett and Young were instrumental in having the age of consent raised from ten to fourteen, and for women gaining the right to be their children's legal guardians.

[18][9] In 1900, the South Carolina Supreme Court ruled in favor of Turnispeed such that the will was overturned and the library did not gain the US$20,000 left to it by Nesblett.

As Nesblett had turned over her private residence to the library trustees in 1896, before creating her second will, the building was not involved in the supreme court's decision.
