The Saint Lawrence River (French: Fleuve Saint-Laurent; Tuscarora: Kahnawáʼkye; Mohawk: Kaniatarowanenneh, meaning "big waterway") is a large river flowing approximately from southwest to northeast in the middle latitudes of North America, connecting the Great Lakes with the Atlantic Ocean. It is the primary drainage conveyor of the Great Lakes Basin. The river traverses the Canadian provinces of Quebec and Ontario and forms part of the international boundary between Ontario, Canada, and New York State in the United States. This geographic entity is coterminous with the commercial Saint Lawrence Seaway.
The St. Lawrence River originates at the outflow of Lake Ontario between Kingston, Ontario, on the north bank, Wolfe Island in mid-stream, and Cape Vincent, New York. From there, it passes Gananoque, Brockville, Morristown, Ogdensburg, Massena, Cornwall, Montreal, Trois-Rivières, and Quebec City before draining into the Gulf of Saint Lawrence, one of the largest estuaries in the world. The estuary portion begins at the eastern tip of Île d'Orléans, just downstream from Quebec City. The river becomes tidal in the vicinity of Quebec City.
The river runs 3,058 kilometres (1,900 mi) from the farthest headwater to the mouth and 1,197 km (743.8 mi) from the outflow of Lake Ontario. The farthest headwater is the North River in the Mesabi Range at Hibbing, Minnesota. Its drainage area, which includes the Great Lakes and hence the world's largest system of freshwater lakes, has a size of 1,344,200 square kilometres (518,998.5 sq mi), of which 839,200 km2 (324,016.9 sq mi) is in Canada and 505,000 km2 (194,981.6 sq mi) is in the United States. The basin covers parts of the provinces of Ontario and Quebec, and the states of Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania, Vermont, and Wisconsin. The average discharge below the Saguenay River is 16,800 cubic metres per second (590,000 cu ft/s). At Quebec City, it is 12,101 m3/s (427,300 cu ft/s). The average discharge at the river's source, the outflow of Lake Ontario, is 7,410 m3/s (262,000 cu ft/s).
The river includes Lake Saint-Louis south of Montreal, Lake Saint Francis at Salaberry-de-Valleyfield and Lac Saint-Pierre east of Montreal. It encompasses four archipelagoes: the Thousand Islands chain near Kingston, Ontario; the Hochelaga Archipelago, including the Island of Montreal and Île Jésus (Laval); the Lake St. Pierre Archipelago (Classified biosphere world reserve by the UNESCO in 2000)  and the smaller Mingan Archipelago. Other islands include Île d'Orléans near Quebec City, and Anticosti Island north of the Gaspé. It is the second longest river in Canada.
The St. Lawrence River is in a seismically active zone where fault reactivation is believed to occur along late Proterozoic to early Palaeozoic normal faults related to the opening of Iapetus Ocean. The faults in the area are rift related and are called the Saint Lawrence rift system.
Though European mariners, such as John Cabot, the brothers Gaspar and Miguel Corte-Real, and Alonso Sanchez in the 15th century and the Norse 500 years still earlier, explored the Gulf of St. Lawrence the first European explorer known to have sailed up the St. Lawrence River itself was Jacques Cartier, during his second trip to Canada in 1535, with the help of Iroquoian chief Donnacona's two sons. As he arrived in the estuary on St. Lawrence's feast day, Cartier accordingly named it the Gulf of St. Lawrence. The land along the river was inhabited at the time by the St. Lawrence Iroquoians. The St. Lawrence River is partly within the U.S. and as such is that country's sixth oldest surviving European place-name.
During the 16th century and up to the 18th, the Saint Lawrence Gulf and River bore witness to the earliest regular Europeans, the Basques, who arrived in pursuit of whales in early 16th century. Basque whalers and fishermen traded with native Americans and set up settlements, leaving vestiges all over the coast of eastern Canada and deep into the Saint Lawrence River. Basque commercial and fishing activity reached its peak prior to the Armada Invencible's disaster (1588), when the Spanish Basque whaling fleet confiscated by King Philip II of Spain was largely destroyed. Initially, the whaling galleons from Labourd were not affected by the Spanish defeat.
Until the early 17th century, the French used the name Rivière du Canada to designate the Saint Lawrence upstream to Montreal and the Ottawa River after Montreal. The Saint Lawrence River served as the main route for European exploration of the North American interior, first pioneered by French explorer Samuel de Champlain.
Control of the river was crucial to British strategy to capture New France in the Seven Years' War. Having captured Louisbourg in 1758, the British sailed up to Quebec the following year thanks to charts drawn up by James Cook. British troops were ferried via the St. Lawrence to attack the city from the west, which they successfully did at the Battle of the Plains of Abraham. The river was used again by the British to defeat the French siege of Quebec under the Chevalier de Lévis in 1760.
Because of the virtually impassable Lachine Rapids, the St. Lawrence was once continuously navigable only as far as Montreal. Opened in 1825, the Lachine Canal was the first to allow ships to pass the rapids. An extensive system of canals and locks, known as the Saint Lawrence Seaway, was officially opened on 26 June 1959 by Elizabeth II (representing Canada) and President Dwight D. Eisenhower (representing the United States). The Seaway now permits ocean-going vessels to pass all the way to Lake Superior.
During the Second World War, the Battle of the St. Lawrence involved submarine and anti-submarine actions throughout the lower St. Lawrence River and the entire Gulf of Saint Lawrence, Strait of Belle Isle and Cabot Strait from May to October 1942, September 1943, and again in October and November 1944. During this time, German U-boats sank several merchant marine ships and three Canadian warships.
In the late 1970s, the river was the subject of a successful ecological campaign (called "Save the River"), originally responding to planned development by the United States Army Corps of Engineers. The campaign was organized, among others, by Abbie Hoffman.

The source of the North River in the Mesabi Range in Minnesota (Seven Beaver Lake) is considered to be the source of the Saint Lawrence River. Because it crosses so many lakes, the water system frequently changes its name. From source to mouth, the names are:
- North River
- Saint Louis River
- Lake Superior
- Saint Marys River
- Lake Huron
- Saint Clair River
- Lake Saint Clair
- Detroit River
- Lake Erie
- Niagara River
- Lake Ontario
- Thousand Islands
The St. Lawrence River is at the heart of many Quebec novels (Anne Hébert's Kamouraska, Réjean Ducharme's L'avalée des avalés), poems (in works of Pierre Morency, Bernard Pozier), and songs (Leonard Cohen's "Suzanne", Michel Rivard's "L'oubli", Joe Dassin's "Dans les yeux d'Émilie"), and André Gagnon's "Le Saint-Laurent"). The river was the setting for the Canadian television drama series Seaway. The river has also been portrayed in paintings, notably by the Group of Seven. In addition, the river is the namesake of Saint-Laurent Herald at the Canadian Heraldic Authority.
