Yuba County is a county located in the U.S. state of California. As of the 2010 census, the population was 72,155. The county seat is Marysville.

Yuba County is included in the Yuba City, CA Metropolitan Statistical Area, which is also included in the Sacramento-Roseville, CA Combined Statistical Area. The county is located in California's Central Valley along the Feather River.


Yuba County was one of the original counties of California, formed in 1850 at the time of statehood. Parts of the county's territory were given to Placer County in 1851, to Nevada County in 1851 and to Sierra County in 1852.

The county was named after the Yuba River by Captain John Sutter for the Native American village Yubu, Yupu or Juba near the confluence of the Yuba and Feather rivers. General Mariano Vallejo stated that the river was named Uba by an exploring expedition in 1824 because of the quantities of wild grapes (uvas silvestres in Spanish) which they found growing on its banks.


According to the U.S. Census Bureau, the county has a total area of 644 square miles (1,670 km2), of which 632 square miles (1,640 km2) is land and 12 square miles (31 km2) (1.9%) is water. It is the fifth-smallest county in California by total area. The county lies along the western slope of the Sierra Nevada, the steep slopes making it prime territory for the siting of hydroelectric power plants.

A portion of the county, where Marysville (the county seat) and most of the population lives, is west of the mountains on the valley floor. There is a great deal of agriculture business in this part of the county, especially fruit orchards, rice fields, and cattle grazing.


National protected areas within Yuba County include portions of the Plumas National Forest and the Tahoe National Forest. In addition to these identified protected areas the county has extensive natural areas consisting of forestation, grassland, riparian area, grassland and other habitats. The county exhibits a considerable diversity of flowering plant species, among which is the yellow mariposa lily, Calochortus luteus.
