Fort Harker, located in Kanopolis, Kansas, was an active military installation of the United States Army from November 17, 1866 to October 5, 1872.
 The fortification was named after General Charles Garrison Harker, who was killed in action at the Battle of Kennesaw Mountain in the American Civil War.
 Fort Harker replaced Fort Ellsworth, which had been located 1.6 km from the location of Fort Harker and was abandoned after the new fortifications at Fort Harker were constructed.
 Fort Harker was a major distribution point for all military points farther west and was one of the most important military stations west of the Missouri River.

 An estimated 500,000 emigrants used these trails from 1843–1869, with up to one-tenth dying along the way, usually due to disease.

 It guarded the American frontier in Indian Territory from 1824 until 1888.
