Elinore Pruitt Stewart (born Elinore Pruitt; June 3, 1876 – October 8, 1933) was a homesteader in Wyoming, and a memoirist who between 1909 and 1914 wrote letters describing her life there to a former employer in Denver, Colorado. Those letters, which reveal an adventurous, capable, and resourceful woman of lively intelligence, were published in two collections in 1914 and 1915. The first of those collections, Letters of a Woman Homesteader, was the basis of the 1979 movie Heartland.
