Olompali (Coast Miwok:Õlõmpõ'llï;[citation needed] Spanish: Olómpali)[1] is a former Native American settlement in Marin County, California.

[4][5] The Coast Miwok had inhabited a site within the State Historic Park continuously from as early as 6000 BC.

[3] After California became part of the United States, its last-standing chief Ynitia (born Huemox) was able to maintain ownership over Olompali.

[3] An article in the Marin Journal from March 1911 mentions that relics and remains of the Olompali people were still scattered all across the county.

Mounds of shell and soil from their settlement have been leveled in 1874 and 1875, and used to fill land in Marin County.
