Tidal river in New Hampshire, United States

The Squamscott River is a 6 mile (10 km) tidal river in southeastern New Hampshire, in the United States, fed by the Exeter River. The first 33 mile (53 km) of freshwater river from Chester to downtown Exeter is known as the Exeter River, and the subsequent 9 mile (14 km) of saltwater from downtown Exeter to the Great Bay tidal estuary is known as the Squamscott River. The combined Exeter Squamscott watershed is and contains 68,245 people. It includes portions of Chester, Raymond, Fremont, Danville, Kingston, East Kingston, Sandown, Kensington, Brentwood, Exeter, Newfields, and Stratham. There are falls and small dams at several locations along the river. The Exeter River drainage basin encompasses an area of 126 square miles (326 km2). The upper 33.3 mile (54 km) of the river, from its headwaters to its confluence with Great Brook in Exeter, were designated into the NH Rivers Management and Protection Program in August 1995.

The Squamscott begins at downtown Exeter and runs north between Newfields and Stratham to Great Bay, which is connected to the Piscataqua River, and eventually feeds into the Atlantic Ocean. After rising at the Great Bridge (a Works Progress Administration project that carries what is now New Hampshire Route 27) in downtown Exeter, the river passes the Phillips Exeter Academy boathouse, then tends north alongside the Swasey Parkway, through the haymarshes, passing by the town's water purification plant and then under Route 101, a major east–west arterial road in New Hampshire. The river next passes under Route 108 at the boundary of Newfields and Stratham. The river then debouches into Great Bay, a broad and shallow tidal estuary, just south of the mouth of the Lamprey River, arriving at the bay from Newmarket. The Squamscott River is 9 mile (14 km) long, and transitions from freshwater to saltwater as it enters the Great Bay estuary.
