Ellen Annette Martin (January 16, 1847 – March 13, 1916) was an early and little-known American attorney who achieved an early victory in securing women's suffrage in Illinois. She was the first woman to vote in Illinois. Ellen Martin graduated the University of Michigan, Ann Arbor law school in 1875 and was admitted to the Illinois bar in 1876. In 2008, the city of Lombard, Illinois, declared April 6 to be "Ellen Martin Day" in commemoration of Ms. Martin's historic victory for women's suffrage.
