Geography
Most of Kingman County is prairie. The South Fork of the Ninnescah River winds its way across the northern part of the county and the Chikaskia River crosses the southern part.

Tradition has it that there was only one tree in the county when it was founded; early settlers planted windbreaks that are magnificent now. The county is in the second tier of counties north of the Oklahoma border. A line drawn through the center of Kansas from north to south would pass through the county.

The county encompasses 864 square miles and at its heart is the huge Byron Walker game preserve and public hunting area. Cheney Lake touches the northeastern corner of the county and the Kingman State Lake is near Calista in the center.

Population
The county has a population of 7,863 (2012 estimate, U.S. Census), with 23 townships and 7 incorporated cities.
