Plumas-Eureka State Park is a California state park located in the Sierra Nevada and Cascade Range in Plumas County, California.

The park, as a mining museum, shows and protects the history of the active mid-19th century California Gold Rush mining period. As a large natural area it shows and protects the serenity of the mountain's meadows, forests, lakes, and granite peaks. Camping, picnicking, biking, fishing, and hiking are offered.

Eureka Peak, formerly Gold Mountain, was the site of some of the first organized ski races in North America. The National Longboard Championship, the longest running ski races since 1911, have been held in the Park at the Eureka Ski Bowl since 1993.

Gold Discovery Days is a living history weekend held in July within the park. The celebration features mining era demonstrations and activities.

The historic mining area includes a museum in the miner's bunkhouse, the Mohawk Stamp Mill, Bushman five-stamp mill, stables, a blacksmith shop, the mine office, and a miner's home "Moriarity House".

A California Historical Landmark marker is located in the park honoring the mining areas of Jamison City, Eureka Mills, Johnstown, and the Eureka Mine.

Plumas-Eureka State Park is in the Sierra Nevada Coniferous Forest ecosystem of the Temperate Coniferous Forests Biome.

The park's animals include golden eagles, porcupines, black bear, deer, weasel, mink, marten, mountain lion, bobcat, fox, and many others.

The park is within the Middle Fork Feather River watershed and encompasses some of its headwaters, including Jamison and Eureka Creeks.

Plumas-Eureka State Park is located about 60 miles north of Lake Tahoe in Northern California. It is five miles west of Blairsden on County Road A-14.

This is one of the 48 California state parks proposed for closure in January 2008 by California's Governor Arnold Schwarzenegger as part of a deficit reduction program since rescinded following public outcry. Plumas-Eureka State Park, except during the winter season, is open to the public.
