Fort Gibson National Cemetery is a United States National Cemetery located inside of the town of Fort Gibson, in Muskogee County, Oklahoma.

It encompasses 48.3 acres (19.5 ha), and as of 2021 had more than 25,000 interments.

Fort Gibson was established in 1833, on a plot of land within the Cherokee nation.

Frontier life was hard, yellow fever was common, and at least three separate cemeteries were created between 1833 and 1857 when the Fort was abandoned.

In 1863 the Fort was remanned by Brigadier General James G. Blunt.
