Fort Wallace (ca. 1865-1882) was a US Cavalry fort built in Wallace County, Kansas to help defend settlers against Cheyenne and Sioux raids. All that remains today is the cemetery, but for a period of over a decade Fort Wallace was one of the most important military outposts on the frontier.
Today, Fort Wallace is represented by a small state-operated museum nearby in the town of Wallace, with relics from the fort as well as photos, reproduction items, and literature covering the post's history and the settlement of the Great Plains.
The old Fort Wallace cemetery still exists, and is located next to the Wallace Township Cemetery at .
