Newry (/ˈnjʊəri/; from Irish An Iúraigh) is a resort town in Oxford County, Maine, United States. The town’s year-round population was 411 at the 2020 census. The town is best known as the home of Sunday River Ski Resort and has a proportionately large seasonal (winter) population. Newry was also the site of one of Maine's worst Cold War aircraft crashes.

First called Sunday River Plantation, it was settled in 1781 by Benjamin Barker and his two brothers from Methuen, Massachusetts, together with Ithiel Smith of Cape Elizabeth. But the settlement was plundered in 1782 by Indians and abandoned. Then John J. Holmes of New Jersey purchased the land in 1794 with his sister's surname on the deed: Bostwick. On June 15, 1805, Bostwick Plantation was renamed by settlers that had come from Newry in what is now Northern Ireland. The name Newry is an anglicization of An Iúraigh, an oblique form of An Iúrach, which means "the grove of yew trees".

The trade route (now Route 26) from Portland to Errol, New Hampshire, completed in 1802, passed through Newry. Farms were established on the intervales, which had excellent soil. Hay was the principal crop. Slopes of the mountains provided pasturage for grazing animals. A sawmill and gristmill were built on the Bear River, and by 1870 the population was 416. Today, Newry is noted as the home of Sunday River Ski Resort.

At 20:15 on June 27, 1960, a United States Air Force tanker of the 380th Air Refueling Squadron departed Plattsburgh AFB to refuel a Strategic Air Command bomber. The Boeing KC-97 Stratofreighter rendezvoused with the B-47 Stratojet bomber at an altitude of 15,500 feet in the Fighting Fox aerial refueling area over Newry. As the bomber maneuvered into refueling position, a lubrication failure caused the tanker's outboard port engine supercharger impeller to disintegrate. Impeller fragments leaving the engine nacelle caused fuel leakage. The bomber observed ignition of the leaking fuel and broke away from formation. The tanker entered a gradual left turn, which became a spiraling spin as the fire rapidly caused structural damage to the port wing. Seven miles away, three hundred people at a Rumford Point drive-in theater observed the tanker spin down, with burning pieces flying off. The fuselage impacted a forested slope of granite boulders and caused a fireball seen fifty miles away in Lewiston. The port wing tip was found in Howard Pond, three miles from the crash site. There were no survivors from the tanker's five-man crew. Wet vegetation limited spread of the fire, but fuel-covered trees were completely consumed and the five-acre hillside wreckage field was discernible for years amid the surrounding forest.

The February 23, 2012, episode of Sins and Secrets (season 2, episode 7, "Newry") told the story of a series of murders that happened at a local B&B in 2006. The convicted killer, charged in 2006 and now serving four consecutive life sentences, was a citizen of Newry.

Substantial lithium deposits were discovered in 2018 on the north side of Plumbago Mountain, which straddles Newry and Andover, Maine. Restrictions on extraction were being debated in the state legislature as of 2023.

According to the United States Census Bureau, the town has a total area of 61.55 square miles (159.41 km), of which 61.52 square miles (159.34 km) is land and 0.03 square miles (0.08 km) is water. Newry is drained by the Bear River and Sunday River, which both flow into the Androscoggin River.
