The Kenilworth Plantation House is a historic plantation house located at 2931 Bayou Road in St. Bernard Parish, Louisiana. The French Creole style house was built circa 1820. During the early 19th century, the French Creole style was the predominant architectural form of St. Bernard Parish; however, most of the parish's French Creole buildings from the period are no longer standing, and Kenilworth is one of the best-preserved examples of the style.

The two-story house has a raised basement, and the upper story is considered the primary living space. A gallery supported by turned collonnettes surrounds both stories of the house; all entrances from the gallery feature French doors. The house's hipped roof has an intricate truss support system and exposed, shaped rafter tails typical of Creole designs.^[2]

The house was added to the National Register of Historic Places on April 24, 2006.^[1]
