Labadieville is a census-designated place (CDP) in Assumption Parish, Louisiana, United States.

Labadieville, originally called "Brûlée Labadie", takes its name from a French pioneer and resident, Jean Louis L'Abadie.

St. Philomena Catholic Church dates from 1848 as an organized parish, and the first mass was said in the home of Widow Zacharie Boudreaux.

During the Civil War, Labadieville was the scene of the Battle of Georgia Landing, Oct. 27, 1862, between Union forces under Gen. Weitzel and a body of Confederate troops under Brig.

Major General Benjamin F. Butler, commanding Union forces in the Department of the Gulf, launched an expedition into the Bayou Lafourche region to eliminate the Rebel threat from that area, to make sure that sugar and cotton products from there would come into Union hands and, in the future, to use it as a base for other military operations.

Gen. Weitzel, Butler's protégé, with five regiments from the Reserve Brigade, Department of the Gulf (numbering about 4,000 men), left Carrollton, 7 miles (11 km) above New Orleans, on Oct. 24, and went up the Mississippi River in transports conveyed by gunboats.

On the 26th, they marched down the Bayou Lafourche 15 miles (24 km) to Napoleonville, but were unable to find the Confederate force known to be in that region.

By means of a floating bridge Gen. Weitzel began crossing his men to the west bank to attack the Rebel troops there.

In 1905, a canal, called the Cancienne, leading east from Lake Verret to Bayou Lafourche near Napoleonville, was constructed.
