Grand Pass was named from the Great Osage Trail that passed through the town.
In 1943, German and Italian prisoners of World War II were brought to Missouri and other Midwest states as a means of solving the labor shortage caused by American men serving in the war effort. Camp Funston at Fort Riley established 12 smaller branch camps, including Grand Pass.
