Newburyport is a coastal city in Essex County, Massachusetts, United States, 35 miles (56 km) northeast of Boston. The population was 18,289 at the 2020 census. A historic seaport with a vibrant tourism industry, Newburyport includes part of Plum Island. The mooring, winter storage, and maintenance of recreational boats, motor and sail, still contribute a large part of the city’s income. A Coast Guard station oversees boating activity, especially in the sometimes dangerous tidal currents of the Merrimack River.

At the edge of the Newbury Marshes, delineating Newburyport to the south, an industrial park provides a wide range of jobs. Newburyport is on a major north-south highway, Interstate 95. The outer circumferential highway of Boston, Interstate 495, passes nearby in Amesbury. The Newburyport Turnpike (U.S. Route 1) still traverses Newburyport on its way north. The Newburyport/Rockport MBTA commuter rail from Boston’s North Station terminates in Newburyport. The earlier Boston and Maine Railroad leading farther north was discontinued, but a portion of it has been converted into a recreation trail.

On January 28, 1764, the General Court of Massachusetts passed “An act for erecting part of the town of Newbury into a new town by the name of Newburyport.” The act begins:

The act was approved by Governor Francis Bernard on February 4, 1764. The new town was the smallest in Massachusetts, covering an area of 647 acres (2.62 km), and had a population of 2,800 living in 357 homes. There were three shipyards, no bridges, and several ferries, one of which at the foot of Greenleaf Lane, now State Street, carried the Portsmouth Flying Stage Coach, running between Portsmouth, New Hampshire, and Boston.

The town prospered and became a city in 1851. Situated near the mouth of the Merrimack River, it was once a fishing, shipbuilding and shipping center, with an industry in silverware manufacture. In 1792, a bridge was built two miles above the town where the river contained an island. Merrimack Arms and Brown Manufacturing Company made Southerner Derringer pistols in their Newburyport factory from 1867 to 1873. The sea captains of old Newburyport (as elsewhere in Massachusetts) had participated vigorously in the triangular trade, importing West Indian molasses and exporting rum made from it. The distilleries were located around Market Square near the waterfront. Caldwell’s Old Newburyport rum was manufactured locally until 1961.

Newburyport once had a fishing fleet that operated from Georges Bank to the mouth of the Merrimack River. It was a center for privateering during the Revolutionary War and War of 1812. Beginning about 1832, it added numerous ships to the whaling fleet. Later, clipper ships were built there. Today, the city gives little hint of its former maritime importance. Notably missing are the docks, which are shown on earlier maps extending into the channel of the Merrimack River, and the shipyards, where the waterfront parking lot is currently located.
