Atsugewi is a recently extinct Palaihnihan language of northeastern California spoken by the Atsugewi people of Hat Creek and Dixie Valley. In 1962, there were four fluent speakers out of an ethnic group of 200, all elderly; the last of these died in 1988. The last fluent native speaker was Medie Webster; as of 1988, other tribal members knew some expressions in the language. For a summary of the documentation of Atsugewi see Golla (2011: 98-99).Astugewi is related to Achumawi.
