Hester C. Jeffrey (c. 1842 - January 2, 1934) was an African American activist, suffragist, and community organizer. She was a national organizer for the National Association of Colored Women's Clubs (NACWC), and helped create African-American women's clubs for such purposes as women's suffrage, helping women with small children, and to raise money for young black women to take classes at what later became the Rochester Institute of Technology. She also worked for the Political Equality Club, the Woman's Christian Temperance Union, and served on the Douglass Monument Committee.
Jeffrey was friends with Susan B. Anthony and was often seen at Anthony's home in Rochester, and was the only layperson to give a eulogy at her funeral service in 1906.Unknown photographer, restored by Adam Cuerden
