{{Main|History of Louisiana#Prehistory}}
Ouachita Parish was the home to many succeeding [[Native Americans in the United States|Native American]] groups in the thousands of years before Europeans colonized the area. Peoples of the [[Marksville culture]], [[Troyville culture]], [[Coles Creek culture]] and [[Plaquemine culture]] built villages and earthwork mound sites throughout the area. Notable examples include the [[Filhiol Mound Site]], located on a natural levee of the Ouachita River.<ref name=FILHIOL>{{cite web|url=http://www.crt.state.la.us/archaeology/moundsguide/filhiol.html|title=Indian Mounds of Northeast Louisiana:Filhiol Mound|access-date=October 20, 2011|url-status=dead|archive-url=https://archive.today/20121224124606/http://www.crt.state.la.us/archaeology/moundsguide/filhiol.html|archive-date=December 24, 2012}}</ref>

The oldest and most significant is [[Watson Brake]], the most ancient mound complex in North America, dated to 5400 BP (before present), or about 3500 [[BCE]]. Its dating changed archeologists' understanding of the antiquity of mounds in North America and what types of cultures constructed them.
