Johnson County was established on December 13, 1834, when it separated from Lafayette County. Johnson County was named after R.M. Johnson, a Kentucky senator and later vice president of the United States. As of 2015 Johnson County has an estimated population of 53,951. There are seven municipalities located in Johnson County: Centerview, Chilhowee, Holden, Kingsville, Knob Noster, Latour, Leeton and Warrensburg, which is the county seat. Communities that no longer qualify as incorporated towns, but are still recognized on our county maps include: Burtville, Columbus, Cornelia, Dunksburg, Elm, Ernestville, Fayetteville, Magnolia, Medford, Montserrat, Owsley, Pittsville, Post Oak, Rose Hill, Slab Town and Sutherland.


Johnson County is also home to University of Central Missouri and Whiteman Air Force Base - home of the Stealth Bomber. Johnson County is approximately fifty miles east of Kansas City and is rapidly growing as commuters move farther from the city.​​
