The Akokisa (Arkokisa, Orcoquiza) Indians were Atakapan-speaking Indians who lived in extreme southeastern Texas between the Trinity and Sabine rivers. They were most commonly encountered around Galveston Bay. It seems likely that the Han and Coaque Indians encountered by Álvar Núñez Cabeza de Vaca in the early sixteenth century were Akokisas, as well as the Caux, who held Simars de Bellisle captive in the early eighteenth century. Most of what is known about the Akokisas comes from mission records. In 1748–49 some of them entered San Ildefonso Mission on the San Gabriel River near the site of present Rockdale, but they left this area when the mission was abandoned in 1755. Nuestra Señora de la Luz Mission was built near the mouth of the Trinity River for the Akokisas and the Bidais in 1756–57 and lasted until 1772. Thereafter little is reported about the Akokisas, although in 1805 they seem to have lived in two settlements, one on the lower Colorado River and the other near the coast between the Neches and Sabine rivers. It seems likely that the Akokisa survivors joined their relatives, the Atákapas, in southwestern Louisiana shortly before the Texas Revolution.
