Casqui was a Native American polity visited in 1541 by the Hernando de Soto expedition. This group inhabited fortified villages in eastern Arkansas.
The tribe takes its name from the chieftain Casqui, who ruled the tribe from its primary village, thought to be located in present day Cross County, Arkansas near the town of Parkin. The suspected site is the focal point of the Parkin Archeological State Park and it has been determined that the site was continuously occupied for at least 500 years. Information about Chief Casqui and his people comes from journals made during the expedition of Hernando de Soto in 1541.
