The Cocopah, sedentary dwellers of the Southwest, inhabited the region along the lower stretch of the Colorado River in what is presently the southwestern corner of Arizona and Sonora, Mexico, bordered on the south by the Gulf of California. Along with the nearby Mojave, Halchidhoma, Maricopa, and Yuma, the Cocopah were Yuman-speaking and were ancient inhabitants of this hot and dry region. Another neighboring Indigenous peoples were the Chemehuevi of the Uto-Aztecan language family.

Because of their efficient use of the land and water resources available to them, the Cocopah could remain in one place and did not have to roam for hunting or gathering purposes. They utilized the annual flooding of the Colorado River, rather than irrigation, to water their crops, including corn, beans, pumpkins, gourds, and tobacco. Both men and women took part in tending the fields. Limited hunting of small game, including rabbits, supplemented the agricultural production for the nation, as did the gathering of mesquite beans and other wild foods by the Indigenous women. The Colorado River provided fish caught by the men with seines, basketry scoops with long handles, weirs made from interlaced branches, and dip nets.

Because of the intense heat of the area, the men wore only narrow breechcloths, while the women wore front and back aprons. Sandals were worn while traveling. Men and women painted their faces and wore tattoos. Hair was worn with bangs covering the forehead. The men twisted the hair on the back of their heads into many thin strands, while the women wore their hair long.

The Cocopah's housing was also adapted to the weather. Houses were little more than flat-roofed structures for shade, with open sides. In winter, rectangular structures with sloping sides and ends, all covered with earth, were utilized. Rabbit skin blankets provided warmth in winter.

The Cocopah lived with little formal government. They held a strong sense of Indigenous unity, with the family being the basic unit within the nation. Chiefs held an advisory role, maintaining intertribal peace and conducting religious ceremonies. Shamans were held in high regard and accompanied chiefs on war parties. War raids were well organized, with the warriors using bows and arrows, clubs, heavy sticks, round hide shields, and feathered staves.

According to the Cocopah Indian Tribe, membership numbers totaled around 1,000 in the mid-2020s. Most members lived on or near the Cocopah Indian Reservation, established in 1917, in Yuma County, Arizona, along the Colorado River. The reservation comprised three noncontiguous pieces of land called the East, West, and North Reservations. The nation established a constitution and a tribal council and is recognized by the federal government as a sovereign Indigenous nation. Various social services are available for members, and many members participate in cultural preservation efforts and environmental stewardship, including securing funding for habitat restoration in the Colorado River Delta. The Cocopah Indian Tribe has also participated in economic development projects, including the Cocopah Casino & Resort, Wild River Family Entertainment Center, and Cocopah Bend Golf Course. Around 300 Cocopah people (Cucapá or Es péi) also lived in Mexico in the early twenty-first century.
