Helen N. Hamilton (January 3, 1874 – September 30, 1949) was North Dakota's first female lawyer.
She was admitted as the state's first female lawyer the same year and proceeded to set up a law practice in Grand Forks, North Dakota.
[6] In 1915, Hamilton was one of the first women to apply for admission to the American Bar Association.
While the ABA ultimately rejected Hamilton's application, it seems likely that Hamilton's effort helped pave the way for the ABA's decision in 1918 to admit its first two women, Mary Florence Lathrop of Denver and Mary Grossman of Cleveland.
In 1999, the University of North Dakota School of Law designated a "Helen Hamilton Day" in her honor.
