The Little River is a 7.3-mile-long (11.7 km) stream in the towns of Kingston and Brentwood in Rockingham County, New Hampshire, United States. It is a tributary of the Exeter River, part of the Great Bay/Piscataqua River watershed in the New Hampshire Seacoast region. The river should not be confused with the Little River of Exeter, another tributary of the Exeter River less than 3 miles (5 km) away.
The Little River rises in the northwestern part of Kingston and follows a winding course generally northeast through flat or slightly hilly terrain. The river turns north as it enters Brentwood and reaches the Exeter River east of Brentwood's town center.
