The Mono (ˈmoʊnoʊ ) are a Native American people who traditionally live in the central Sierra Nevada, the Eastern Sierra (generally south of Bridgeport), the Mono Basin, and adjacent areas of the Great Basin. They are often grouped under the historical label "Paiute" together with the Northern Paiute and Southern Paiute – but these three groups, although related within the Numic group of Uto-Aztecan languages, do not form a single, unique, unified group of Great Basin tribes. Today, many of the tribal citizens and descendants of the Mono tribe inhabit the town of North Fork (thus the label "Northfork Mono") in Madera County. People of the Mono tribe are also spread across California in: the Owens River Valley; the San Joaquin Valley and foothills areas, especially Fresno County; and in the San Francisco Bay Area. The "Mono" lived on both sides of the Sierra Nevada and are divided into two regional tribal/dialect groups, roughly based on the Sierra crest: Eastern Mono Southernmost Northern Paiute live on the California-Nevada border on the eastern side of the Sierra Nevada in the Owens Valley (Mono: Payahǖǖnadǖ/Payahuunadu – "place/land of flowing water") along the Owens River (Wakopee) and south to Owens Lake (Pacheta). They are also known as the "Owens Valley Paiute" Western Mono on the west side in the south-central foothills of the Sierra Nevada, including the "Northfork Mono," as labeled by E.W. Gifford, an ethnographer studying people in the vicinity of the San Joaquin River in the 1910s. The current tribal name "Mono" is a Yokutsan loanword from the tribe's western neighbors, the Yokuts, who however hereby designated the Owens valley Paiutes as the southernmost Northern Paiute band living around "owens lake" / Mono Lake as monachie/monoache ("fly people") because fly larvae was their chief food staple and trading article and not the "Mono". This "Kucadikadi Northern Paiute Band", whose autonym Kutsavidökadö/Kutzadika'a means "eaters of the brine fly pupae", are also known as Mono Lake Paiute or Owens Valley Paiute, a holdover from early anthropological literature, and are often confused with the non-Northern Paiute ethnic group of the Western mono "Mono".
