The Louisiana State Arboretum 600 acres (240 ha), is an arboretum located on Louisiana Highway 3042, approximately 13 km (eight miles) north of Ville Platte, Louisiana inside of Chicot State Park, USA, and bordering a branch of Lake Chicot. Established in 1961, it is the oldest state-supported arboretum in the United States.
Initial efforts to establish a Louisiana Arboretum in the 1950s were led by Caroline Dormon, A. G. Lawton, and J. D. Lafleur Sr. The majority of these efforts were near Ville Platte and included Magnolia Garden Club, the Rotary Club, and the Chamber of Commerce. In spring of 1961, the State Parks and Recreation Commission ordered the creation of the Louisiana State Arboretum.
