Alice Mary Robertson (January 2, 1854 – July 1, 1931) was an American educator, social worker, Native Americans' rights activist, government official, and politician who became the second woman to serve in the United States Congress, and the first from the state of Oklahoma. Robertson was the first woman to defeat an incumbent congressman. She was known for her strong personality, commitment to Native American issues, and anti-feminist stance.
Until the election of Mary Fallin in 2006, Robertson was the only woman elected from Oklahoma to Congress.
