The Pomoan, or Pomo , languages are a small family of Native Californian languages spoken by the Pomo people who formerly occupied the valley of the Russian River and the Clear Lake basin. The Pomoan languages are severely endangered – with the exception of Kashaya, which had few dozen speakers in the 1990s, they are spoken by only a handful of elderly people. Northern Pomo and Northeastern Pomo are without known speakers and presumed to be extinct.
