Mary Jane Richardson Jones (1819 – December 26, 1909) was an American abolitionist, philanthropist, and suffragist. Born in Tennessee to free black parents, Jones and her family moved to Illinois during her teenage years. Along with her husband, John Jones, she was a leading African-American figure in the early history of Chicago. The Jones household was a center of abolitionist activity in the pre-Civil War era, helping hundreds of fugitives fleeing slavery.
