The Nisqually River is a river in west central Washington in the United States, approximately 81 miles (130 km) long. It drains part of the Cascade Range southeast of Tacoma, including the southern slope of Mount Rainier, and empties into the southern end of Puget Sound. Its outlet was designated in 1971 as the Nisqually Delta National Natural Landmark.
The Nisqually River forms the Pierce–Lewis county line, as well as the boundary between Pierce and Thurston counties.
