Minnie Keith Bailey (July 24, 1869 - March 19, 1953) was an American poet and suffragette. She was the first woman in Oklahoma to publish a poetry collection with her 1905 book, Life's Undertow. In 1906 she spoke at the Oklahoma constitutional convention in favor of granting women in Oklahoma the right to vote upon statehood. She was president of the Enid Suffrage Association, a vice president for the Oklahoma Equal Suffrage Association, and a delegate to the 1918 National Women's Suffrage Association convention. Bailey was one of 92 women to sew a 46 star, 12 foot by 20 foot United States flag for the state of Oklahoma for Flag Day in 1908 in Guthrie, Oklahoma.
Minnie Keith was born near White Cloud, Kansas on July 24, 1869, to Uri Seeley Keith and Mary F. Grossman of Ohio. The Keith family were descended from Field Marischall Keiths of Scotland, and her ancestors emigrated to Bridgewater, Massachusetts in 1662. Her father and grandfather fought in the Civil War in Ohio and were related to Corporal Luke Keith who fought in the American Revolution. She was educated at the Atchison Institute, and received her B.A. from Western Normal College of Shenandoah, Iowa, graduating as valedictorian in 1888.
In 1889 she married John Roberts Bailey in McPherson, Kansas, and they had one daughter, Mildred. Her husband worked for the railroads and in grain distribution. They moved to Oklahoma in 1901, first living in Garber, then Enid from 1902 to 1917, and settled in Perry until her death in 1953.

She was also involved with the Enid Shakespeare Club, Women's Relief Corps, and Alpha Chautauqua.
