The Simpson Park Mountains, also known as the Simpson Park Range, are located in Lander and Eureka counties, in central Nevada in the western United States. The mountains reach an elevation of 9,147 feet (2,788 m) at Fagin Mountain, and cover an area of approximately 310 square miles (800 km2). US Route 50 crosses the very southern end of the range at Hickison Summit between Eureka and Austin.
