Greenville (formerly, Oregon Hill) is a former settlement in Yuba County, California, United States. It was located on Little Oregon Creek southeast of Challenge, at an elevation of 2182 feet (665 m).
A post office operated at Greenville from 1857 to 1860.
In the late nineteenth century, Greenville had a few hundred residents, a store, and a school. A narrow-gauge logging railroad connecting Challenge with the nearby Beanville Mill stopped in Greenville. By 1957, Greenville was essentially a ghost town.
