West Newbury is a town in Essex County, Massachusetts, United States. Situated on the Merrimack River, its population was 4,500 at the 2020 census.

Originally inhabited by Agawam or Naumkeag peoples, West Newbury was settled by English colonists in 1635 as part of neighboring Newbury. After 15 years of English colonization, a 30 acre section of land around Indian Hill in current day West Newbury was purchased from an indigenous man Great Tom for three pounds.

On February 18, 1819, the General Court of Massachusetts passed an act "to incorporate the town of Parsons." The initial proposals had been made in the late 18th century, but determined resistance from the town of Newbury, which had already lost Newburyport, blocked the measure for decades. On June 14, 1820, the legislature passed another act to change the name to West Newbury.

West Newbury has evolved from a rural farming town into a community facing the issues of balancing development and need for affordable housing against the townspeople's desire to maintain West Newbury's rural charm and character have been in play for at least fifty years. In 1969 local writer Margaret Coit called West Newbury a "hill-framed town that Lowell Thomas once described as 'the Garden of Eden of America,'" saying that as active farming faded away, West Newbury had become, "in its population and pattern of thinking ... virtually a suburb."

Between 1820 and the early 1900s, an active Quaker community existed in West Newbury. The Quaker Meetinghouse stood at what is now 114 Turkey Hill Street and the Quaker Burial Ground, which was established in the 1850s, is located along the Artichoke Reservoir

During the 19th century, West Newbury was home to a vibrant industrial scene. The town was renowned for its comb making industry. Beginning in the 1840s, small home-based comb shops gave way to large-scale factories that produced horn combs and hair adornments. S.C. Noyes, located at 320 Main Street, was the last remaining comb factory in town and shut its doors in 1904. In addition to comb making, a shoe factory operated where the West Newbury Pizza Company currently exists.

The West Newbury Historical Society, a non-profit, maintains the Hills House Museum at the historic William Hills and Hannah Chase House. The home was built in 1780 and the property contains several outbuildings, one of which is a cobbler's shop. The museum boasts a collection of horn combs and adornments manufactured in West Newbury, along with cooper's tools original to the house.

In 1952, Julian D. Steele became the first African-American town Moderator in Massachusetts when he was elected to the position in West Newbury.

The town's oldest continually-operating farm is Long Hill Orchard. The farm has been active since 1896, and has a long and intriguing history. Today, in addition to the apple orchard, the farm is home to a popular community-supported agriculture program and farm to table dining events.

West Newbury is a part of Massachusetts' North Shore, as well as the Merrimack Valley regions of the state. It lies along the south banks of the Merrimack River, 10 miles (16 km) upstream from the Atlantic Ocean. The town is located approximately 13 miles (21 km) northeast of Lawrence and 34 miles (55 km) north of Boston. It is bordered by Merrimac and Amesbury to the north, Newburyport to the east, Newbury to the southeast, Groveland to the southwest, and Haverhill to the west. The Rocks Village Bridge across the Merrimack River is the only access to the northern banks of the river in town; there is no direct route into Merrimac and Amesbury.

West Newbury is separated from Newburyport by the Artichoke River and its upper and lower reservoirs. Several other rivers and brooks, including the Indian River, flow through the town. The southern corner of town is part of the Crane Pond Wildlife Management Area, and two other protected areas, the Riverbend Recreation Area and Mill Pond Recreation Area, are located in the northern part of town. The town's highest point is on Archelaus Hill in the center of town. Significant efforts have been made by residents to maintain the rural character of the town through advocacy for the preservation of open spaces. West Newbury is well known for its many hills: Pipestave Hill, Archelaus Hill, Brake Hill, Ilsey Hill, Indian Hill, Long Hill and Meetinghouse Hill.

According to the United States Census Bureau, the town has a total area of 14.7 square miles (38.1 km), of which 13.4 square miles (34.8 km) is land and 1.3 square miles (3.3 km), or 8.65%, is water.

West Newbury and its residents were the models for Popperville, the setting of Virginia Lee Burton's children's story Mike Mulligan and His Steam Shovel. The town hall where the story ends is patterned after West Newbury's Old Town Hall. West Newbury also provided the geographical inspiration for the Mad Scientists' Club series of stories by Bertrand R. Brinley. Portions of John Cena's music video, "Right Now", were shot in West Newbury, with the remainder filmed at Hampton Beach, New Hampshire. In the late summer and fall of 2008, various scenes from Mel Gibson's film Edge of Darkness were shot on Church Street.

West Newbury is home to Emery House, monastery guesthouse and sanctuary of the Society of St. John the Evangelist.

Many farms remain in West Newbury. In 2019 the town, in conjunction with Essex County Greenbelt Association, purchased an agricultural preservation restriction for Brown Spring Farm, permanently eliminating rights to develop the farmland and making it affordable for a new farmer. Long Hill Orchard is the town's oldest continually-operating farm. A number of smaller farms exist in West Newbury, including Maple Crest Farm, several Christmas tree farms, and numerous horse stables and equestrian facilities.

The town has two primary outdoor recreational areas, Mill Pond and Pipestave Hill, which offer walking trails, horseback riding trails, as well as space for canoeing, fishing, and kayaking. Equestrian events are regularly held by the West Newbury Riding and Driving Club throughout the riding season. Additionally, the Myopia Hunt Club holds an annual fox hunt through the town during the fall.

Efforts to maintain West Newbury's rural charm have been ongoing; the Town has purchased large swaths of land designated as Open Space by the West Newbury Open Space Committee.
