Jessie Belle Hardy Stubbs MacKaye (1876 – April 18, 1921) was an American suffragist.

She was the head surgical nurse at St. Luke's hospital in Chicago and met her first husband, Dr. F. Gurney Stubbs there.

Dr. Stubbs passed away from pneumonia in 1910 and Hardy Stubbs moved to New York City afterward, attending Columbia University’s School of Philanthropy and becoming the legislative chair of the Women's Peace Society.

[1] She was noted for "urging all women to remain unmarried or to refuse to bear children" to express the seriousness of female suffrage.

[3][4] While grieving her death, husband Benton MacKaye began formulating the idea that became the Appalachian Trail, as his wife had loved long-distance walking and hiking.
