Eureka County is a county in the U.S. state of Nevada. As of the 2010 census, the population was 1,987, making it the second-least populous county in Nevada. Its county seat is Eureka.

Eureka County is part of the Elko Micropolitan Statistical Area.


Eureka County was established in 1873 and formed from Lander County after silver was discovered more than 100 miles (160 km) east of Austin. The residents of the new mining camp complained that Austin was too far to go for county business and a new county was created. It was named for the ancient Greek term, Eureka, meaning, "I have found it." This term was used earlier in California and other locations. Eureka has always been the county seat.
