Ada McPherson Morley (August 26, 1852 – December 9, 1917) was an American author, suffragist and rancher. Early in her time in New Mexico, she and her husband edited a newspaper and took on the Santa Fe Ring both in print and in business matters. Morley became involved with the New Mexico chapter of the Women's Christian Temperance Union (WCTU) and later served as president. She was also involved in women's suffrage in New Mexico and helped recruit women into the Congressional Union (CU) later in her life. Morley owned a ranch in the Datil Mountains where she raised cattle and was able to host meetings.
