Prairieville is an unincorporated community in Ascension Parish, Louisiana, United States. It is south of Baton Rouge and north of Gonzales, Louisiana.

Prairieville is an expanding bedroom suburb of Baton Rouge. Its name comes from the once plentiful pastures and prairies that were visible from Highway 73 (Jefferson Hwy.) and U.S. Route 61. The most notable of these was the Phillips Farm. The farmhouse is still a local landmark in Prairieville, although the original owner died in 2005. The house is lined with live oaks and a white planked fence surrounds the grounds. The pasture was sold off in 1992 at the start of the suburban development...

Prairieville is an expanding bedroom suburb of Baton Rouge. Its name comes from the once plentiful pastures and prairies that were visible from Highway 73 (Jefferson Hwy.) and U.S. Route 61. The most notable of these was the Phillips Farm. The farmhouse is still a local landmark in Prairieville, although the original owner died in 2005. The house is lined with live oaks and a white planked fence surrounds the grounds. The pasture was sold off in 1992 at the start of the suburban development and a 250-resident subdivision, named'Seven Oaks'', surrounds the farm where the pastures were.

In 2006, the farmhouse was sold at auction following the death of Dr. Carey A. Phillips. The tract of land (including the house) will be further developed for housing.

In recent decades, Prairieville has benefited from white flight out of Baton Rouge, with new residents particularly drawn to the area by its high-performing public schools and low crime rate. Prairieville has an estimated population of 30,000 and is thinking about incorporating. It would be the largest city in Ascension Parish. Prairieville is in one of the fastest growing parishes in Louisiana.
