city, Berkshire county, northwestern Massachusetts, U.S. It lies along the Hoosic River at the western end of the Hoosac Tunnel (extending 5 miles 【8 km】 under the Hoosac Range) and the Mohawk Trail scenic highway, 22 miles (35 km) north of Pittsfield.

North Adams was the site of Fort Massachusetts, which was built by the Massachusetts Bay Colony in 1745 and burned the following year in the French and Indian War. The site's permanent settlement dates from the 1770s, when a Quaker group arrived from Rhode Island. Originally part of Adams, it was set off and incorporated as the town of North Adams in 1878. Waterpower from the Hoosic led to early industrialization (including textile milling), and blast furnaces and shoes were also produced in the mid-19th century. The 4.7-mile (12-km) Hoosac (rail) Tunnel was completed in the mid-1870s. Electronics manufacturing was prominent from 1930 to the mid-1980s. The city's economy is now diversified, with services (education, health care, and utilities), retail trade, and printing and engraving accounting for most employment.

Massachusetts College of Liberal Arts was opened as a normal (teacher-training) school in 1894. A natural rock bridge (part of a state park) crosses Hudson Creek within North Adams, and Mount Greylock State Reservation and Savoy Mountain State Forest are nearby. Inc. city, 1895. Pop. (1990) 16,797; (2000) 14,641.
