Caldwell County is a county located in Missouri, United States. As of the 2020 census, the county's population was 8,815. It is part of the Kansas City metropolitan area. Its county seat is Kingston. The county was organized December 29, 1836 and named by Alexander Doniphan to honor John Caldwell, who participated in George Rogers Clark's Native American Campaign of 1786 and was the second Lieutenant Governor of Kentucky. Caldwell County was originally established as a haven for Mormons, who had been driven from Jackson County in November 1833, and had been refugees in adjacent Clay County since. The county was one of the principal settings of the 1838 Missouri Mormon War, which led to the expulsion of all Latter Day Saints from Missouri, following the issuance of an "extermination order" by then–Governor Lilburn Boggs.
