Alford is a town in Berkshire County, Massachusetts, United States. It is part of the Pittsfield, Massachusetts Metropolitan Statistical Area. The population was 486 at the 2020 census.

Alford was first settled in 1756 as part of a land purchase from the Shauanum Stockbridge Mahican tribe by a group led by Timothy Woodbridge. The town, originally part of Great Barrington, separated in 1769 and was officially incorporated in 1773. It was named for Colonel John Alford of Charlestown, who was known for preaching Christianity to Native Americans and for sponsoring a theology professorship at Harvard College's Divinity School. The town has been mostly agricultural throughout its existence, however in 1799, large marble deposits were found on the western slopes of Tom Ball Mountain, and for the next 90 or so years it would be an industrious mining town. This would come to an end when the railroad was laid in a neighboring valley, rendering the last operating quarries of Alford unable to compete.

Around New Year's Day, 1776, General Henry Knox passed into Massachusetts through the town, bringing cannons from Fort Ticonderoga eastward to help end the Siege of Boston. Today, this route is known as the Knox Trail, and a marker is located at the state line.

Alford is surrounded by hills and mountains of the Taconic Range. The Green River, a tributary of the Housatonic River, flows through the southwest corner of town, and Alford Brook flows through the central part of town, eventually flowing into the Green River in neighboring Great Barrington. Several other brooks flow into these two waterways. To the northeast of town, Tom Ball Mountain peaks just over the town line in West Stockbridge, with its western face being somewhat marshy.

Alford is home to the western terminus of Massachusetts Route 71, a short continuation of New York State Route 71. The Knox Trail follows this route into the state, and the road heads southeastward into Egremont before ending in Great Barrington. There are no other state routes in the town, with few local roads crossing through town. The nearest interstate, Interstate 90 (the Massachusetts Turnpike), passes through neighboring West Stockbridge, with its "turn-around" Exit 1 being 8 miles (13 km) north of Alford.

Bus service is available in Pittsfield as well as in Great Barrington, provided by Peter Pan Bus Lines.
