Jonah LeRoy "Doane" Robinson (October 19, 1856 – November 27, 1946) was a state historian of South Dakota.
He is known for conceiving of the idea for the Mount Rushmore National Memorial in the Black Hills, which he believed would stimulate tourism to the area.
The Lakota people, who consider the Black Hills to be sacred ground, objected to this project but were unable to prevent it.
This territory used to be within the Great Sioux Reservation, but the United States broke up and decreased the size of the reservations after gold was discovered in the Black Hills.
Robinson gained support from the US Senator from South Dakota, and in 1929 President Calvin Coolidge approved the project after Congress authorized funding.
