Old Hickory is a neighborhood of metropolitan Nashville named in honor of President Andrew Jackson who was nicknamed "Old Hickory." This area is located in the Hadley Bend section of eastern Davidson County. The area is probably best known for being a former company town as the site of a large DuPont plant. Many of the houses in Old Hickory were built to house DuPont employees and supervisors in the early days of the factory's existence. Old Hickory is bordered by the Cumberland River on the north and west, Old Hickory Lake to the east, and the former city of Lakewood to the south. To the north of the area is also the location of Old Hickory Lock and Dam. The main street through the area is Old Hickory Boulevard (Tennessee State Route 45). Many historic homes are located in the area known as the Village of Old Hickory, containing a number that are listed on the National Register of Historic Places.
