Russell is a town in Hampden County, Massachusetts, United States. The population was 1,643 at the 2020 census. It is part of the Springfield, Massachusetts Metropolitan Statistical Area.

Russell was originally part of the Pocumtuc (also called Deerfield) nation, who spoke an Algonquian language. Like most native peoples, they were decimated by smallpox, then their participation in King Philip's War 1675–1676 proved their undoing as victory by colonial forces led to the dispersal of remnants of this tribe west into New York and north into Canada.

Although the way was open for settlement beyond the Pioneer Valley lowlands, the thin, rocky soil and hilly topography of uplands to the west delayed settlement until about 1725, when there was no more promising land left to settle in the valley. Because river valleys in the hilly areas were subject to cold air pockets and late frosts—especially during the Little Ice Age that persisted until the late 19th century—most early settlement was in uplands in and near South Quarter. Relatively unproductive soils and small fields were not conducive to growing cash crops, so farming was more of a subsistence nature. Most of what was consumed on these farms was homemade or bartered for.

The upland farm population peaked around 1800, when more productive farmland opened up beyond the Appalachian Mountains in western New York and the Northwest Territory—today's Great Lakes states. Employment opportunities became significant by about 1825 as the first (water power-dependent) Industrial Revolution unfolded in New England. The cash income gave farmsteads access to manufactured goods and imported food such as cane sugar from the West Indies in lieu of local maple products. Farming became more of a part-time occupation and a growing number of farms were abandoned, gradually reverting to forest until only stonewalls and cellar holes remain.

The Industrial Revolution led to development in the Westfield River valley, as the water power potential of the three cascades was developed for industrial use. Three villages developed around mills at the cascades, and the easy grades along the valley were utilized for a railroad route across the Berkshires' 1,400 feet (430 m) of relief.

A small upstream village near the Huntington border was called Crescent Mills. Originally a Chapin and Gould Paper Company mill, Texxon still operates a mill there that makes special fabrics for shoes. The middle settlement and the town's administrative center is called Russell Village. Westfield River Paper Company manufactured glassine and other specialty papers there until it was decommissioned and then bought for a proposed biomass electric plant utilizing local cordwood. Russell Village was a virtually self-sufficient community as late as the 1950s, with several stores, a barbershop, and several restaurants; then increasing automobile ownership brought the greater commercial offerings in Westfield and other Pioneer Valley cities within reach.

The lower industrial village was named Woronoco after a local tribe, and the local cascades were once called Salmon Falls, presumably because Atlantic salmon were observed and captured there. Strathmore Paper Company manufactured high-quality bond papers at this location until it was taken over by International Paper and then decommissioned. Strathmore was originally purchased by Horace A. Moses in 1904. Moses, later co-founder of Junior Achievement, was a visionary social engineer as well as an industrialist who developed Woronoco as a model company town with housing of a notably high standard and buildings accommodating a wide variety of community activities. The factory, and the town it created, were based upon his journey to the factory town of Strathmore, Scotland. Moses also developed a 1,600-acre (6.5 km²) estate around Russell Pond in South Quarter, where he raised both award-winning apples and prized hunting dogs. He later sold off sections of the estate to the Hampden Council of the Boy Scouts of America. Today, the Horace A. Moses Scout Reservation contains many buildings original to Moses and his staff, including his summer home, which is known simply as "The Manor House". The property is thought to be one of the last homes of the rare Scottish thistle, which Moses imported from Scotland in the 1930s.

In 1965 Russell joined with neighboring towns to form Gateway Regional School District that now educates some 1,300 students at an annual cost to taxpayers of about $15,000 per student. With very little industrial and commercial property to share this tax burden, Russell has one of the highest tax rates per unit assessed value in the state.^{[citation needed]}
