The Satsop Hills are foothills of the Olympic Mountains in Mason County, Washington north of Matlock, Washington, between Wynoochee Lake to the west and Lake Cushman to the east.

The Satsop River, with a 300-square-mile (780 km²) watershed, rises in the hills and flows south to the Chehalis River. Where the river rises, 160 inches (4,100 mm) of annual precipitation qualifies as a temperate rainforest, a term used applied by some publications to the Satsop watershed. The Wynoochee Oxbow meteorological station on the west end of the hills (47°17′57″N 123°39′07″W / 47.29917°N 123.65194°W / 47.29917; -123.65194 (Wynoochee Oxbow)) has both the highest average annual rainfall and the second highest ever recorded in the continental United States. The hills lie partly in the Olympic National Forest but not quite in the Olympic National Park. In a 1916 geological survey, hills in the vicinity of Matlock were included with the Black Hills of Thurston County, but may have been describing formations on the East Fork of the Satsop, to the south of the area described above.

Peaks in the Satsop Hills include:

Forest fires have struck the hills repeatedly. The term "Satsop hills" has been used at least since 1885 when the Morning Oregonian used it to describe the location of forest fires.
