The Ashuelot River is a tributary of the Connecticut River, approximately 64 mi (102 km) long, in southwestern New Hampshire in the United States. It drains a mountainous area of 425 sq mi (1105 kmē), including much of the area known as the Monadnock Region.

It rises out of Butterfield Pond south of Sunapee Mountain in Pillsbury State Park, near Washington in southwestern Sullivan County. It flows southwest through Ashuelot Pond into Cheshire County, then south past Keene and Swanzey and along the east side of the Pisgah Mountains. At Winchester, approximately 3 mi (5 km) from the Massachusetts state line, it turns west, flowing past Ashuelot and joining the Connecticut from the east at Hinsdale, in the extreme southwest corner of New Hampshire.
The lower river valley was later colonized by pioneers in the early 1700s, with settlement continuing to the upper valley by the latter part of the 1700s.
AshuelotRiver Park in Keene provides a small boat access, while the proximity of roads along the river and numerous pull-offs provide informal access to cartop boats along much of the river's 64 miles.
The AshuelotRiver is both a cold and warm water fishery that provides habitat for approximately 15 resident species, including eastern brook trout, large and small mouth bass, and walleye.
The Connecticut River is the largest river in New England, flowing south from the Connecticut Lakes in northern New Hampshire, along the border between New Hampshire and Vermont, through Western Massachusetts and central Connecticut into Long Island Sound at Old Saybrook, Connecticut.
The river carries a heavy amount of silt, especially during the spring snow melt, from as far north as Quebec.
The difficulty of navigation on the river is the primary reason that it is one of the few large rivers in the region without a major city near its mouth.
