Mohawk Trail State Forest is a Massachusetts state forest located in Charlemont. The forest is managed by the Department of Conservation and Recreation.

Mohawk Trail State Forest is a rustic 6,400 acre forest of mountain ridges, gorges, and old-growth forests. Elevations range from around 600 to 2,080 feet. The state forest is popular for fishing and camping.

The forest has two main rivers, the Deerfield River and the Cold River, and several small streams in which live a variety of trout. Other wildlife that may be seen include deer, bobcats, and black bears.

The park offers 56 wooded campsites and 6 overnight cabins.

A state forest is a forest that is administered or protected by some agency of a sovereign state or U.S. state.

The precise application of the term varies by jurisdiction. For example:

The Mohawk Trail began as an Native American trade route which connected Atlantic tribes with tribes in Upstate New York and beyond. It followed the Millers River, Deerfield River and crossed the Hoosac Range.

Today the Mohawk Trail is part of Massachusetts Route 2, which was created as one of the United States' first scenic highways. It follows much of the original Indian trail, from Orange, Massachusetts to Williamstown, Massachusetts, for about 65 miles (105 km) through the Berkshire mountains.

Around the western portion of the road is the Mohawk Trail State Forest, a 6,400-acre (26 km²) forest, known for its camping, and occasional encounters with bobcats and black bears.

The road passes exceptionally close to Vermont, and to many locals, a common scenic drive follows most of the Trail, and departs north into Vermont to Harriman Reservoir or Ball Mountain State Park.

The Mohawk Trail was added to the National Register of Historic Places on April 03, 1973, reference number 73000283.
