The Mount Tom Range is a traprock mountain range located in the Connecticut River Valley of Massachusetts. It is part of the Metacomet Ridge that extends from Long Island Sound near New Haven, Connecticut, north through the Connecticut River Valley of Massachusetts to nearly the Vermont border. A popular outdoor recreation resource, the range is known for its continuous west facing cliffs and its rugged, scenic character. It is also notable for its unique microclimate ecosystems and rare plant communities, as well as significant historic sites, such as the ruins of the 18th century Eyrie House located on Mount Nonotuck.

The Mount Tom Range rises steeply between 500 and 1,100 feet (150 and 340 m) above the Connecticut River Valley below; it is roughly 4.5 miles (7 km) long by 1.5 miles (2.4 km) wide at its widest point, although the ruggedness of the terrain makes the actual area much larger.

The entire range is sometimes referred to as "Mount Tom". Oriented from south to north, the range is located within the towns of Easthampton and Holyoke.

The Metacomet Ridge continues south from the Mount Tom Range as East Mountain and east across the Connecticut River as the Holyoke Range. The Metacomet Ridge is broken to the north; the Mount Tom Range is separated from the Pocumtuck Ridge, 9 miles (14 km) away by a relatively low-lying area punctuated with occasional rises. The east side of the range drains into the Connecticut River thence to Long Island Sound; the west side drains into the Manhan River, thence to the Connecticut River.
