The Chiwaukum Mountains are a north–south mountain range in central Washington, United States. They stretch from Snowgrass Mountain at {{coord|47|41|N|120|56|W|}}, to {{coord|47|45|N|120|54|W|}}.

The mountains are made of schist, part of the Nason terrane. The original rock in the Nason terrane was laid down 210 Myr ago. The terrane then smashed into the western coastline of the continent, and the Mount Stuart batholith intruded into it in the late Cretaceous. The intrusion of the granitic rock metamorphosed the rock into schist.{{cite web | url=http://geopubs.wr.usgs.gov/i-map/i1661/chelpama.pdf | title=GEOLOGIC MAP OF THE CHELAN 30-MINUTE BY 60-MINUTE QUADRANGLE, WASHINGTON | publisher=United States Geological Survey | accessdate=2018-06-15 }}

In July 2014, the lightning-caused Chiwaukum Creek Fire burned the east flank of the Chiwaukum Mountains.
