Platte County is a county located in the northwestern portion of the U.S. state of Missouri and is part of the Kansas City metropolitan area. As of the 2020 census, the population was 106,718. Its county seat is Platte City.[1] The county was organized December 31, 1838,[2] from the Platte Purchase,[3] named for the Platte River.

The land for the airport was originally in an unincorporated portion of Platte County before being annexed by Platte City, and eventually Kansas City.

The Republican Party controls politics at the local level in Platte County. Republicans hold all of the elected positions in the county. However, Governor Jay Nixon carried the county in his two successful elections, and in 2004, Claire McCaskill of Jackson County narrowly won a majority of the county's votes over Republican victor Matt Blunt. While the county has swung to the Republican party, the presence of Kansas City has helped keep the county competitive into the 21st century.
