The Stillwater Range is a mountain range located in western Nevada in the United States. It is a SSW-NNE running ridge, approximately 70 miles long. It cuts across the center of Churchill County and extends partway into Pershing County. The Stillwater Range separates the Carson Sink (to the west) from Dixie Vally (to the east). To the north, a low pass separates it from the East Range . To the south, the Sand Springs Pass separates it from the Sand Springs Range. Nestled against the south end of the range is Sand Mountain, an enormous 600 foot tall sand dune which draws off-road vehicle enthusiasts from across Nevada and California.

A series of earthquakes measuring 6.6-7.1 on the Richter Scale, centered beneath or near the Stillwater Range, occurred between July and December of 1954. As the area was then (and still is) sparsely populated, no fatalities and little property damage resulted. Extensive surface rupturing can be seen on the east slope of the range.

The principal peaks of the Stillwater Range include Table Mountain (elevation 8330 feet), Mount Lincoln (elevation 8450 feet) and Job Peak (elevation 8790 feet).
