Frank T. Hopkins (August 11, 1865 unsubstantiated – November 5, 1951) was a self-proclaimed professional horseman who at one time performed with the Ringling Brothers Circus.

Hopkins said he was born to a Lakota mother, although this remains unsubstantiated, and European-American father, that he grew up in both cultures, and that he learned to ride and care for horses at an early age.

In his autobiographical memoir (unpublished in his lifetime) and accounts to friends, he claimed to have been featured as one of the "Rough Riders of the World" in Buffalo Bill's Wild West show, which toured in Europe[4] as well as the United States.

[11] Hopkins' accounts of his life and the story of the race in Arabia were the inspiration for the 2004 film Hidalgo, written by John Fusco,[12] directed by Joe Johnston, and starring Viggo Mortensen.

[2][6] Lakota scholar, historian and doctor Vine Deloria says "Hopkins' claims are so outrageously false that one wonders why the people were attracted to this material at all.
