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.

US Route 50 crosses the very southern end of the range at Hickison Summit between Eureka and Austin.

The Monitor, Kobeh and Antelope valleys lie to the southeast.

Trees found in the range include: western juniper (Juniperus occidentalis), Utah Juniper (Juniperus osteosperma), and Single-leaf Pinyon (Pinus monophylla).

Coyotes and pikas roam the Simpson Park Mountains.
