The Osawatomie State Hospital Burial Grounds are located north of the city of Osawatomie, Kansas, and approximately 1/2 mile east of the State Hospital. It is a small cemetery consisting of 346 markers identifying people, mostly patients, who had no families that would claim them. Burials were discontinued during the early 1950's. All 346 markers are only identified with a number, with the exception of a couple stones which have been replaced with identifying named markers. The entire cemetery was photographed in 2019, and photos for each numbered stone were matched with the associated named record in Find-A-Grave. Markers 1-343 are individual graves, beginning in 1928. Markers 344-346 are three mass graves with disinterred burials from the original cemetery on the hospital grounds prior to 1928.
