Prairie City was a gold-mining community that once sat on the American River in the Sierra Nevada foothills, near present-day Folsom in Sacramento County, California, near Prairie City Road, Sacramento.

Though the names of these people are unknown, it is assumed they were Prairie City residents.

Their skeletal remains were re-buried in the Mormon Island relocation cemetery, south of Folsom Lake.

The general site of Prairie City is a California Historical Landmark (#464).

[1] The Folsom subdivision Prairie Oaks was named for it, because it is believed that the city once stood in this general area.
