The Hia C-eḍ Oʼodham ("Sand Dune People"), also known as Areneños or Sand Papagos,[2] are a Native American peoples whose traditional homeland lies between the Ajo Range, the Gila River, the Colorado River, and the Gulf of California.

The Hia C-eḍ Oʼodham are no longer nomadic, and the majority today live in or near Ajo, Arizona, or the small settlements of Blaisdell and Dome near Yuma.

According to historical sources, the Hia C-eḍ Oʼodham were friendly with the Cocopah, the Quechan, and the Halchidhoma.
