The Satsop River is a stream in the U.S. state of Washington. It has three main tributary forks, the East Fork, West Fork, and Middle Fork Satsop Rivers. The main stem Satsop River is formed by the confluence of the West and East Forks. The Middle Fork is a tributary of the East Fork. The three forks are much longer than the main stem Satsop itself, which flows south from the confluence only a few miles to join the Chehalis River near Satsop, Washington. Other significant tributaries include the Canyon River and Little River, both tributaries of the West Fork Satsop, and Decker Creek, a tributary of the East Fork Satsop River. The Satsop River's major tributaries originate in the Olympic Mountains and its southern foothills, the Satsop Hills, within Grays Harbor and Mason counties. Most of the Satsop River's watershed consists of heavily wooded hill lands. The upper tributaries extend into Olympic National Forest, approaching but not quite reaching Olympic National Park.
The Satsop River watershed is located east of the Wynoochee River and south of the Skokomish River watersheds.
The main stem Satsop River originates at the confluence of the East and West Forks and flows generally south to Satsop, where it empties into Chehalis River at Chehalis river mile 20.2. U.S. Route 12 crosses the river near its mouth. The main stem river flows through a broad valley used for farming.
The river has several significant tributaries, including the West, East, and Middle Forks. These forks are significant rivers in their own right and unite only a few miles north of the Chehalis River. The forks are all much longer than the main stem Satsop River.
