Missouri H. Stokes (July 24, 1838 – November 27, 1910) was an influential American social reformer and writer associated with the temperance movement of the long nineteenth century. Her dedication to the cause of temperance led her to become a member of the Atlanta Woman's Christian Temperance Union (WCTU) in 1880, and she played significant roles within the organization, including serving as its secretary and State Corresponding Secretary. Stokes made substantial contributions to the passage of Georgia's General Local Option Law and Scientific Instruction in Public Schools, advocating for these measures through her writings and by sending thousands of petitions. Born in Gordon County, Georgia, Stokes came from a family with a strong history of activism and education. She received her education from the Hannah More Female Seminary and became an educator herself, teaching at various institutions and displaying a passion for foreign missions. Despite personal tragedies, including the loss of her brother in the Civil War and her mother's death, Stokes's commitment to temperance and education remained unwavering. Her multifaceted contributions as an educator, temperance worker, and writer left a lasting impact on the social reform movement in the United States.
