Kennett is a city in, and the county seat of, Dunklin County, Missouri, United States. The city is located in the southeast corner (or "Bootheel") of Missouri, 4 miles (6.4 km) east of Arkansas and 20 miles (32 km) from the Mississippi River. It has a population of 10,932 according to the 2010 Census. Kennett is the largest city in the Bootheel, a mostly agricultural area.
White settlers built log cabins in the area in the first half of the 19th century, naming their settlement Chilletecaux in honor of a Delaware Indian chief who lived there. The town was renamed Butler in the late 1840s. Due to mail delivery problems because of other jurisdictions named the same, the settlement was renamed as Kennett, in honor of the mayor of the city of St. Louis, Luther M. Kennett.
In the 1890s, a railroad reached the area, stimulating growth in the town. In that same period, the state began construction of a massive drainage program in the St. Francis River basin, which was floodplain and wetlands.
