Marionville is a city in Lawrence County, Missouri, United States. The population was 2,225 at the 2010 census.

Marionville is known for its large population of white squirrels.

Marionville was platted in 1854. The city name has been erroneously attributed as namesake of Francis Marion. It is, in fact, named to honor early settler and founder, James Marion Moore. Other names were considered - Jamestown/Jamesville and Moorestown/Mooresville - but were already taken and Moore's middle name was then used. A post office called Marionville has been in operation since 1864. On March 12, 2006, a tornado hit the town, destroying houses and killing two people. It was rated as an F3.

The town's two most famous residents are a colony of white squirrels (inhabitants since the 1880s) and legendary tubist Harvey Phillips.

Marionville is located at 37°0′1″N 93°38′17″W / 37.00028°N 93.63806°W / 37.00028; -93.63806 (37.000361, -93.638026).

According to the United States Census Bureau, the city has a total area of 1.76 square miles (4.56 km), all land.

Marionville has a population of white squirrels, which is one of a handful of such populations in the United States. They can be seen in yards near the Ozarks Methodist Manor.

On April 21, 2014, the Marionville mayor, Dan Clevenger, resigned. After longtime resident and career bigot Frazier Glenn Miller Jr. shot and killed three people outside a Jewish Community Center in Overland Park, Kansas, Clevenger initially stated that he supported Miller's beliefs but not his actions. Clevenger's lost history of serving as Miller's mouthpiece for anti-Semitic rants were widely reported, and Clevenger made a bumbling series of remarks that centered around him recalling how nice Miller was (as long as he was interacting with other white men) and that he still felt "some" of Miller's conspiracy theories about Jews being evil were accurate (they weren't, and Clevenger was further discredited by confirmation of this). Two Marionville officials resigned and stated they would not serve in a government that included Celvenger, and a 4–1 vote by aldermen to begin the impeachment process prompted Clevenger's decision to quit. Clevenger later said that none of his opponents were against his views and simply used his actions as an excuse to get his office, and speculated that he would be able to win back the Mayor's office in the near future. As of September 2024, Clevenger has not attempted any such campaigns.
