Cooter is a city in Pemiscot County, Missouri, United States. The population was 440 at the 2000 census.
According to Houck's History of Missouri the town of Cooter was named in 1854 for the Coutre family, early settlers to the area. The Coutres are believed to have emigrated from France in the mid-1700s to the Franco-American village of St. Genevieve. Portell Coutre travelled inland westward, and in 1795 is listed in documents as being a merchant in the area of present-day Cooter. As often happened with unusual or foreign names in the largely illiterate rural America of the time, the towns name was spelled as it sounds.
