Olompali State Historic Park is a 700-acre (2.8 km2) California State Park in Marin County, California. It consists of the former Rancho Olómpali and was the site of the famed Battle of Olómpali during the Bear Flag Revolt. Rancho Olómpali was purchased by the Californian government in 1977, which turned it into a public park.
