Christian County covers approximately 564 square miles in Southwest Missouri and is bordered by Greene, Lawrence, Stone, Taney, Douglas and Webster Counties. Though Christian County is one of the fastest growing counties in the State of Missouri and is considered part of the Springfield Metropolitan Statistical Area (Greene, Christian, Dallas, Polk and Webster Counties), the southern part of the County is predominantly rural in character.

Incorporated communities include the Village of Saddlebrooke and the cities of Billings, Clever, Fremont Hills, Highlandville, Nixa, Ozark, and Sparta. Of these cities, Nixa and Ozark are the largest with Census 2000 populations of 12,124 and 9,665, respectively. Saddlebrooke, which incorporated in 2003, is the smallest community with an estimated population of 15.
