Benjamin Harrison Eaton (December 15, 1833 – October 29, 1904) was an American politician, entrepreneur and agriculturalist in the late 19th and early 20th century.

A member of the Republican Party, he served as the fourth Governor of Colorado, from January 1885 to January 1887, with the nickname of the "farmer governor".
