Battle Mound Site, Archaeological site in Magnolia, United States.

Battle Mound Site is an earthen mound in Lafayette County, Arkansas, in the Great Bend region of the Red River basin, near Magnolia. Its main mound measures about 670 feet long, 320 feet wide and 34 feet high, the largest of the Caddoan Mississippian culture. Four low rises at the site are believed to be constructed earthwork mounds.

The mounds were built between 1200 and 1400 when Caddoan Mississippian societies thrived in this region. This period saw the development of organized settlements with distinct social divisions in the southeastern area.

The site lies near Magnolia in Lafayette County, Arkansas, in the Great Bend region of the Red River basin. It is associated with Caddo peoples of the Caddoan Mississippian culture, a regional variant of the Mississippian tradition, and the Italian source dates occupation to between 1400 and 1680 CE.

The site is open and easy to explore with natural trails around the mounds requiring no special equipment. Visitors should wear sturdy shoes and dress for the weather, as the riverside location can be muddy or wet depending on the season.

The site's name comes from the Battle family, who owned the land in the 19th century; the mounds themselves were built centuries earlier. Archaeologist Alex D. Krieger of the University of Texas at Austin excavated there with assistant Lynn E. Howard from June 25 to September 11, 1948, but the field notes and full analysis were never published. More recently, Duncan P. McKinnon has conducted archaeogeophysical research at the site.
