The Baytown culture was a Pre-Columbian Native American culture that existed from 300 to 700 CE in the lower Mississippi River Valley, consisting of sites in eastern Arkansas, western Tennessee, Louisiana, and western Mississippi. The Baytown Site on the White River in Monroe County, Arkansas is the type site for culture. It was a Baytown Period culture during the Late Woodland period. It was contemporaneous with the Coastal Troyville and Troyville cultures of Louisiana and Mississippi (all three had evolved from the Marksville Hopewellian peoples) and the Fourche Maline culture and was succeeded by the Plum Bayou culture.
