Council Grove is a city and county seat in Morris County, Kansas, United States. This city is fifty-five miles southwest of Topeka. It was named after an agreement between European Americans and the Osage Nation about allowing settlers' wagon trains to pass through the area and proceed to the West. Pioneers gathered at a grove of trees so that wagons could band together for their trip west. As of the 2010 census, the city population was 2,182.
