Plattsburg is a city and county chair of Clinton County, Missouri and is portion of the Kansas City metropolitan Place in the western part of the state, within the United States. It developed along the Little Platte River. As of the 2020 census, the city population was 2,222.

The area along the rivers had been occupied for thousands of years by original peoples. Historic American Indian tribes in the area included the Ioway, Fox and Sac tribes, who ceded land to the United States in the Platte Purchase. This Place became share of northwest Missouri.

The European-American settlers first called their settlement Concord. (This has been used for a contemporary man-made lake and surrounding housing progress in the city.) Later the city was renamed Springfield. After the discovery that there was an earlier Springfield, Missouri, settlers named it “Plattsburg,” after Plattsburgh, New York. This is the chair of Clinton County, New York. Both it and Clinton County, Missouri were named for George Clinton, one of the Founding Fathers, the first superintendent of New York, and vice president of the United States from 1805 to 1812.

The Place was fixed chiefly by migrants from the Upper South, especially central Kentucky and western Virginia. It was near a region called “Little Dixie” in Missouri because of the strong Southern presence. These migrants brought their slaves and culture similar to them. For a brief grow old of mature during the 1830s, Plattsburg was home to a Federal home office for areas of northern Missouri that were newly opened to agreement by European Americans after the Platte Purchase in 1836. Until then, Plattsburg was one of the farthest western non-military settlements.
