The Kawaiisu (also Nuwa or Nuooah) are a Native American group which lives in the southern California Tehachapi Valley and across the Tehachapi Pass in the southern Sierra Nevada Mountains to the north, toward Lake Isabella and Walker Pass. Historically, the Kawaiisu also traveled eastward on food-gathering trips to areas in the northern Mojave Desert, to the north and northeast of the Antelope Valley, as far east as the Panamint Valley, the Panamint Mountains, and the western edge of Death Valley.
Before European contact, the Kawaiisu lived in permanent winter villages of 60 to 100 people. They often divided into smaller groups during the warmer months of the year and harvested California native plants in the mountains and deserts, and animals, for food and raw materials.
The Kawaiisu were related by language and culture to the Southern Paiute of southwestern Nevada and the Chemehuevi of the eastern Mojave Desert of California. They may have originally lived in the desert before coming to the Tehachapi Mountains region, perhaps as early as 2000 years ago or before.
The Kawaiisu have been known by several other names, including the Caliente, Paiute, and Tehachapi Indians, but they called themselves Nuwa or "people." The Kawaiisu maintained friendly relations with the neighboring Kitanemuk and also participated in cooperative antelope drives (driving herds of antelope into traps so they could be more easily slaughtered) with the Yokuts, another group living in the San Joaquin Valley.
In 2011, The Kawaiisu Project received the Governor’s Historic Preservation Award for its efforts to document the Kaiwaiisu language and culture, including "the Handbook of the Kawaiisu, language teaching ... the Kawaiisu Language and Cultural Center, [and] the Kawaiisu exhibit at the Tehachapi Museum."  A local newspaper noted in 2010, "There are also several hundred living Kawaiisu descendents, even though a pervasive misconception believes them to be all gone." 
The Kawaiisu language is a member of the Southern Numic division of the Uto-Aztecan language family. The Kawaiisu homeland was bordered by speakers of non-Numic Uto-Aztecan languages. The Kitanemuk to the south spoke Takic, the Tübatulabal to the north spoke the Tübatulabal language a linguistic isolate. The Yokuts to the west were non-Uto-Aztecan. Because they also spoke a Southern Numic language, the Chemehuevi to the east are the closest linguistic relatives to Kawaiisu.The Kawaiisu was in the Great Plains region in America.
Estimates for the pre-contact populations of most native groups in California have varied substantially. Alfred L. Kroeber proposed the combined 1770 population of the Kawaiisu, Koso, and Chemehuevi as 1,500. He estimated the surviving population of the Kawaiisu, Koso, and Chemehuevi in 1910 as 500.
