Napoleonville (/ˌnæpəˈliːənvɪl/) is a village and the parish seat of Assumption Parish, in the U.S. state of Louisiana.^[3] The population was 660 at the 2010 census.^[4] It is part of the Pierre Part Micropolitan Statistical Area. The village is best known as the location where the film Because of Winn-Dixie, based on Kate DiCamillo's Newbery Prize-winning novel, was shot. The book was set in (fictional) Naomi, Florida.

As early as 1807 the community that later became Napoleonville was known as "Canal". This canal extended west from Napoleonville to Lake Verret.^[5] The town was named by a soldier who served under Napoleon Bonaparte. The soldier is buried in the nearby town of Plattenville in the Cemetery of Our Lady of the Assumption Catholic Church located on Hwy 308 south.

The first permanent settlements in this region were made by the French and Spanish (including Isleños) about the middle of the 18th century along Bayou Lafourche, between the present towns of Donaldsonville and Napoleonville. From 1755 to 1764, the population was increased by the immigration of the exiled Acadians who entered the area clearing the land and building comfortable homes. The town was officially incorporated on March 11, 1878.^[6]
