September 2001 satellite image of the Niagara River. Flowing from Lake Erie in the south (bottom of image) to Lake Ontario in the north, the river passes around Grand Island before going over Niagara Falls, after which it narrows in the Niagara Gorge. Two hydropower reservoirs are visible just before the river widens after exiting the gorge. The Welland Canal is visible on the far left side of this image. (Source: NASA Visible Earth)

The Niagara River (// ny-AG-ər-ə) is a river that flows north from Lake Erie to Lake Ontario. It forms part of the border between the province of Ontario in Canada (on the west) and the state of New York in the United States (on the east). There are differing theories as to the origin of the river's name. According to Iroquoian scholar Bruce Trigger, Niagara is derived from the name given to a branch of the locally residing native Neutral Confederacy, who are described as being called the Niagagarega people on several late-17th-century French maps of the area. According to George R. Stewart, it comes from the name of an Iroquois town called Ongniaahra, meaning "point of land cut in two".
The river, which is occasionally described as a strait, is about 58 kilometres (36 mi) long and includes Niagara Falls in its course. The falls have moved approximately 11 kilometres (6.8 mi) upstream from the Niagara Escarpment in the last 12,000 years, resulting in a gorge below the falls. Today, the diversion of the river for electrical generation has significantly reduced the rate of erosion. The total drop in elevation along the river is 99 metres (325 ft). The Niagara Gorge extends downstream from the Falls and includes the Niagara Whirlpool and another section of rapids.
Power plants on the river include the Sir Adam Beck Hydroelectric Power Stations (built in 1922 and 1954) on the Canadian side, and the Robert Moses Niagara Power Plant (built in 1961) on the American side. Together, they generate 4.4 gigawatts of electricity. The International Control Works, built in 1954, regulates the river flow. Ships on the Great Lakes use the Welland Canal, part of the Saint Lawrence Seaway, on the Canadian side of the river, to bypass Niagara Falls.
The Niagara River also features two large islands and numerous smaller islands. Grand Island and Navy Island, the two largest islands, are on the American and Canadian sides of the river, respectively. Goat Island and the tiny Luna Island split Niagara Falls into its three sections, the Horseshoe Falls, Bridal Veil Falls, and American Falls. Unity Island lies further upstream, alongside the city of Buffalo.
The Niagara River and its tributaries, Tonawanda Creek and the Welland River, formed part of the last section of the Erie Canal and Welland Canal. After leaving Lockport, New York, the Erie Canal proceeds southwest until it enters Tonawanda Creek. After entering the Niagara River, watercraft then proceed southward to the final lock, where a short section of the canal allows boats to avoid the turbulent shoal water at the river intake and enter Lake Erie. The Welland Canals used the Welland River as a connection to the Niagara River south of the falls, allowing water traffic to safely re-enter the Niagara River and proceed to Lake Erie.
The Niagara River and Falls have been known outside of North America since the late 17th century, when Father Louis Hennepin, a French explorer, first witnessed them. He wrote about his travels in A New Discovery of a Vast Country in America (1698).
The Niagara River was the site of the earliest recorded railway in America. It was an inclined wooden tramway built by John Montresor (1736–1799), a British military engineer, in 1764. Called "The Cradles" and "The Old Lewiston Incline," it featured loaded carts pulled up wooden rails by rope. It facilitated the movement of goods over the Niagara Escarpment in present-day Lewiston, New York.
Several battles occurred along the Niagara River, which was historically defended by Fort George (Canadian side) and Fort Niagara (American side) at the mouth of the river and Fort Erie (Canadian side) at the head of the river. These forts were important during the French and Indian War and the American Revolutionary War. The Battle of Queenston Heights took place near the river in the War of 1812.
The river was an important route to liberation before the American Civil War, when many African-Americans escaping slavery on the Underground Railroad crossed it to find freedom in Canada. The Freedom Crossing Monument stands on the bank of the river in Lewiston to commemorate the courage of the escaping slaves and the local volunteers who helped them secretly cross the river.
On the Canadian side of the river the provincial agency Niagara Parks Commission maintains all of the shoreline property, including Fort Erie, except the sites of Fort George (a National Historic Site maintained federally by Parks Canada), as a public greenspace and environmental heritage.
On the American side, the New York State Office of Parks, Recreation and Historic Preservation maintains several state parks adjacent to Niagara Falls and the Niagara River.
Cities and settlements
Cities and towns along the Niagara River include:
The Niagara River is listed as a Great Lakes Areas of Concern in The Great Lakes Water Quality Agreement between the United States and Canada.
The Niagara River has a long history of both road and rail bridges spanning the river, both upstream and downstream of the Falls. This history includes numerous bridges that have fallen victim to the harsh conditions of the Niagara Gorge, such as landslides and icepacks.
The following parks are located along the Niagara River:
A Niagara River Greenway Plan is in progress in the United States.

|The Niagara River originates at the north-east end of Lake Erie, and flows north to its mouth at Lake Ontario.|
|Black Rock Canal||United States||Black Rock Canal flows within and parallel to the east shore of the Niagara river near Buffalo, New York, and was built to extend the navigation period in the Niagara River through a greater part of the winter.

United States Coast Guard Fort Niagara Station was once a United States Army post. There are no Canadian Coast Guard posts along the river. Fort Mississauga, Fort George and Fort Erie are former British and Canadian military forts (last used 1953, 1965 and 1923 respectively) and are now parks.
Navy Island Royal Naval Shipyard was used by French in 18th Century as a naval base and by Royal Navy from 1763 as a small shipyard and abandoned around 1818 after the ratification of the Rush–Bagot Treaty in 1817.
On the Canadian side the Niagara Parkway travels along the River from Lake Ontario to Lake Erie.
NY 18F lines the river on the state side from Fort Niagara to Lewiston. Niagara Scenic Parkway on the state side only travels along the River from the Falls to Lewiston. The remaining river sections (with some interruptions) are covered by the LaSalle Expressway, NY 384, NY 266 and I-190 (Niagara Thruway) / New York Thruway.
