Newburyport, city,Essex county, northeasternMassachusetts, U.S. It lies at the mouth of theMerrimack River, 30 miles (48 km) north-northeast ofBoston. Settled in 1635 (as part of Newbury), its location attracted early fishing,shipbuilding, and craft industries and led to its incorporation as a separate town in 1764. Its sheltered harbour was home port for a largemerchant fleet that brought wealth to the town in the years prior to theAmerican Revolution. The Jefferson Embargo of 1807–08 (against all foreign trade), a disastrous fire in 1811, and theWar of 1812 set a decline in motion that ended the town’s importance as a commercial port. A brief economic boom was experienced during the 1840s when local shipyards produced several famous clipper ships under the direction ofDonald McKay. After 1850 the city’s production of textiles, shoes, silverware, andrum was significant. Tourism and light manufacturing are now the economic mainstays.

Stately Federal-style houses (built by shipowners and sea captains) line the city’s streets as a reminder of its mercantile heritage; one of them, Cushing House (1808), is now the headquarters of the local historical society. The Custom House Maritime Museum is housed in a structure (1835) designed byRobert Mills. A statue honours the abolitionistWilliam Lloyd Garrison, a native of Newburyport. Recreational areas include Maudslay State Park and the city forest. The Parker River National Wildlife Refuge is in theadjacent town of Newbury. Inc. city, 1851. Pop. (2000) 17,189; (2010) 17,416.
