The Pomo are a Native American people of California. Historical Pomo territory in Northern California was large, bordered by the Pacific Coast to the west, extending inland to Clear Lake, mainly between Cleone and Duncans Point. One small group, the Tceefoka, lived in the vicinity of present-day Stonyford, Colusa County, were they were separated from the majority of Pomo lands by Yuki and Wintuan speakers.

The Coast Miwok are an Indigenous people of California that were the second-largest tribe of the Miwok people. Coast Miwok inhabited the general area of modern Marin County and southern Sonoma County in Northern California, from the Golden Gate north to Duncans Point and eastward to Sonoma Creek. Coast Miwok included the Bodega Bay Miwok, or Olamentko (Olamentke), from authenticated Miwok villages around Bodega Bay, the Marin Miwok, or Hookooeko (Huukuiko), and Southern Sonoma Miwok, or Lekahtewutko (Lekatuit). While they did not have an overarching name for themselves, the Coast Miwok word for people, Micha-ko, was suggested by A. L. Kroeber as a possible endonym, keeping with a common practice among tribal groups and the ethnographers studying them in the early 20th Century and with the term Miwok itself, which is the Central Sierra Miwok word for people.
