Occidental is a census-designated place (CDP) in Sonoma County, California, United States. The population was 1,115 at the 2010 census.
Founded in 1876, Occidental was a stop on the North Pacific Coast Railroad connecting Cazadero to theSausalito ferry. In return for donating right-of-way to the railroad, a local landowner named "Dutch Bill" Howards received a lifetime railway pass, and the station was named after him.The railway caused a rapid expansion of the timber industry, and by 1877 there were six sawmills in the Occidental area. Trains also brought vacationers from San Francisco.
