Olivehurst (formerly, Denniston)[3] is a census-designated place (CDP) in Yuba County, California, United States.

People from the town have been known to refer to this group of people as "Okies", a term originally for those from Oklahoma who were escaping the "dust bowl" Oklahoma had become during the Great Depression.

These "Okies" were following migrant workers such as those of Chinese, Japanese, Filipino, Mexican and Native American background.
