The Taensa were a Native American people whose settlements at the time of European contact in the late 17th century were located in present-day Tensas Parish, Louisiana. The meaning of the name, which has the further spelling variants of Taenso, Tinsas, Tenza or Tinza, Tahensa or Takensa, and Tenisaw, is unknown. It is believed to be an autonym. The Taensa should not be confused with the Avoyel, known by the French as the petits Taensas, who were mentioned in writings by explorer Pierre Le Moyne d'Iberville in 1699. The Taensa are more closely related to the Natchez people and both are considered descendants of the late prehistoric Plaquemine culture.

Coles Creek culture is a Late Woodland archaeological culture in the Lower Mississippi valley in the Southeastern Woodlands. It followed the Troyville culture. The period marks a significant change in the cultural history of the area.

Although many of the classic traits of chiefdom societies are not yet manifested, by 1000 CE the formation of simple elite polities had begun. Coles Creek sites are found in Arkansas, Louisiana, and Mississippi. It is considered ancestral to the Plaquemine culture.

It was a major ceremonial center that was contemporaneous with other large Plaquemine sites including Emerald, Holly Bluff, and Winterville and whose main occupation period occurred during the protohistoric period from 1500 to 1650 CE. Parts of the site were excavated by Clarence Bloomfield Moore in 1910 and 1911, and by Lauren Elizabeth Downs in 2007-2009. The mounds are listed on the Mississippi Mound Trail.
