Oaklawn Plantation, Historic plantation house in Natchitoches Parish, Louisiana, United States

Oaklawn Plantation is a three-story French Creole house with fourteen chimneys and a large gallery, located on Louisiana Highway 494 southeast of Natchitoches. It was built in 1830 for Narcisse Prudhomme and is listed on the National Register of Historic Places.

The mansion was built in 1830 for Narcisse Prudhomme as the center of a large cotton plantation. Its construction and layout reflect the wealth and operations of Louisiana plantation agriculture during that era.

Oaklawn takes its name from the oak grove around the house near Natchez on Louisiana Highway 494. The Prudhomme family held the plantation from 1830 until the heirs of Achille Prudhomme divided and sold the land after his death. In 1916 Charles Edgar Cloutier, husband of Adeline Prudhomme, a great-grandniece of Narcisse Prudhomme, bought the property back into the family.

The house stands on Louisiana Highway 494 southeast of Natchitoches, in Natchitoches Parish; the site is private property, so the three-story facade, gallery and fourteen chimneys are seen from the road. It was listed on the National Register of Historic Places on March 28, 1979.

Oaklawn was bought in 1916 by Charles Edgar Cloutier, husband of Adeline Prudhomme, a great-grandniece of builder Narcisse Prudhomme, returning the house to the family that built it in 1830. It is now owned by Robert Harling, who wrote the play Steel Magnolias, filmed in 1989 by Herbert Ross.
