The Atakapa /əˈtækəpə, -pɑː/ or Atacapa were an Indigenous people of the Southeastern Woodlands, who spoke the Atakapa language and historically lived along the Gulf of Mexico in what is now Texas and Louisiana.
They included several distinct bands. They spoke the Atakapa language, which was a linguistic isolate.
The Trinity River is a 710-mile (1,140 km) river. It rises in extreme northern Texas, a few miles south of the Red River. The headwaters are separated by the high bluffs on the southern side of the Red River.
The Trinity River was previously identified as the stream that the Caddo called Arkikosa in Central Texas and Daycoa nearer the coast. However, in 2022, language preservationists from the Caddo Nation determined their ancestral language lacked the letter “R” sound. Arkikosa was likely a corruption or misspelling of the word Akokisa. In the vernacular of another tribe, the Atakapa who settled in the Gulf Coast woodlands, Akokisa means “river people.” French explorer Robert Cavelier de La Salle, in 1687, named the river, Riviere des canoës ("River of Canoes"). In 1690 Spanish explorer Alonso de León named it, "La Santísima Trinidad" ("the Most Holy Trinity").

Approximately 200 miles (320 km) long, it drains a largely rural area of forests and bayou country, meandering southward to the Gulf of Mexico. The name "Calcasieu" most likely comes through French from the Atakapa language Katkōsh Yōk ('Crying Eagle'), the name of a local Atakapa leader.
