Bullfrog County was an uninhabited county in the U.S. state of Nevada created by the Nevada Legislature in 1987. It comprised a 144-square-mile (370 km2) area around Yucca Mountain enclosed by Nye County, from which it was created. Its county seat was located in the state capital of Carson City 270 miles (430 km) away, and its officers were appointed by the governor rather than elected.
