Moriah is a town in Essex County, New York, United States. Lying within the Adirondack Park, it is situated in the eastern part of the county, 47 miles (76 km) by road south-southwest of Burlington, Vermont, 55 miles (89 km) south of Plattsburgh, 115 miles (185 km) north of Albany, and 116 miles (187 km) south of Montreal, Quebec. The population was 4,798 at the 2010 census.

This area was inhabited for thousands of years by varying cultures of indigenous peoples. At the time of European encounter, the area was inhabited chiefly by the historic Iroquoian-speaking Mohawk of the Iroquois Confederacy to the west of Lake Champlain, with the Algonquian-speaking Mahican people to the south.

In 1749, French Jesuits attracted numerous Iroquois (mostly Onondaga fleeing warfare in the western part of present-day New York) to a site on the Oswegatchie River near present-day Ogdensburg. The Jesuit priests founded a mission village and fort. The Iroquois were required to convert to Catholicism to live there. The converted Iroquois and their descendants became known as the "Oswegatchie", and were considered "nephews" to the Six Nations of the Iroquois. They were among the Seven Nations of Canada that allied with the French during the Seven Years' War (known as the French and Indian War on the North American front) and with the British during the American Revolutionary War, in part due to their strong trading ties and cultural links. After the Seven Years' War (French and Indian War) and British victory, the colonial government granted some of its soldiers land in the region, which was ceded to Britain by the French.

It was not until 1785, after the American Revolutionary War, when most of the Iroquois allies went to Upper Canada with the Loyalists, that the first European-American permanent settlement was made here. At the time, local Native Americans still hunted in the area. They were called the St. Regis and Oswegatchie Indians, although both groups were Catholic Iroquois, primarily Mohawk and Onondaga. Relations were initially friendly, but American settlement patterns pushed the Native Americans from their hunting grounds. (The St. Regis group were Catholic Mohawk who lived at the reserve of Akwesasne, whose territory along the St. Lawrence River included land within the boundaries of both Canada and New York. Today it is recognized in the United States as the St. Regis Mohawk Reservation and in Canada as Akwesasne.)

The Town of Moriah was formed in 1808 from the town of Elizabethtown.

The discovery and mining of iron in the Adirondacks caused a boom in the local economy. This area also processed iron in smelting, and shipped products from Port Henry on Lake Champlain. These operations were conducted from 1824 until 1971. The Iron Center Museum in Port Henry recalls and interprets that past era.

Winter ice-fishing for smelt on the frozen Lake Champlain has been a popular sport for more than a century. Tourists come to join residents in this activity.

According to the United States Census Bureau, the town has a total area of 71.1 square miles (184.2 km), of which 64.5 square miles (167.0 km) is land and 6.6 square miles (17.1 km), or 9.31%, is water.

The eastern town line is formed by Lake Champlain and the border of Vermont.

New York State Route 9N is a north-south highway near Lake Champlain. Interstate 87, the Northway, crosses the northwestern corner of Moriah.
