At the request of William "Brawdie" Johnson, a blacksmith, a post office was established at Mitchell in 1873. Johnson, the first postmaster, suggested the name Mitchell after John Hipple Mitchell, a U.S. Senator from Oregon. Senator Mitchell held the office in 1873−1879, 1885−1897, and 1901−1905. Platted in 1885, the community was incorporated in 1893.
In 1872 the first school in Wheeler County was established near Mitchell, and in 1874 it was relocated into the town itself.
