Camden Expedition Sites is a National Historic Landmark consisting of eight historic sites where events of the Civil War's Camden Expedition occurred. The sites are spread across seven counties. The sites are:
- Elkin's Ferry Battleground
- Prairie d'Ane Battlefield, near Prescott in Nevada County, Arkansas
- the Confederate State Capitol building (Arkansas), in Historic Washington State Park
- Fort Southerland on Bradley Ferry Road, in Camden, Ouachita County, Arkansas
- Fort Lookout on Van Buren Road, in Camden, Ouachita County, Arkansas
- Poison Spring Battlefield a state park on Highway 76, near Chidester in Ouachita County, Arkansas.
- Marks' Mills Battlefield, itself a state park, and
- Jenkins' Ferry Battlefield, itself a state park
Each of the sites is individually listed on the National Register of Historic Places.
The National Historic Landmark was declared in 1994.
Eight or nine sites?
It is stated at the National Historic Landmark (NHL) summary that there are nine sites included in the NHL, although that summary only lists only the above eight by name. The NHL nomination document clearly describes only eight sites. An Arkansas state webpage states that the Old U.S. Arsenal Building (meaning the Tower Building of the Little Rock Arsenal, in Little Rock, Pulaski County, Arkansas, where the expedition started) is included in the NHL. The photo set that accompanies the NHL nomination includes photos of the U.S. Arsenal Building as well as of the eight other sites, so it is unclear whether the Arsenal site is part of the NHL or not. It is unclear whether it was intended to be included but was dropped, or whether it was added after the NHL nomination document was completed.
