Cornwall is a city in Eastern Ontario, Canada, situated where the provinces of Ontario and Quebec and the U.S. state of New York converge. It is Ontario's easternmost city. Although it is the seat of the United Counties of Stormont, Dundas and Glengarry, Cornwall is administered independently from the county.

Cornwall is named after the English Duchy of Cornwall; the city's coat of arms is based on that of the duchy with its colours reversed and the addition of a "royal tressure," a Scottish symbol of royalty.

It is the urban centre for the surrounding communities of Long Sault and Ingleside to the west; the Mohawk Territory of Akwesasne to the south; St. Andrews West and Avonmore to the north; and Glen Walter, Martintown, Apple Hill, Williamstown, and Lancaster to the east.

The city is located along the north shore of the St. Lawrence River and is home to the St. Lawrence Seaway Management Corporation, which oversees navigation and shipping activities for the St. Lawrence Seaway. It lies within the Quebec City–Windsor Corridor along Ontario Highway 401, is a major port of entry from the United States into Canada, and is positioned to support some of Cornwall's largest industries, which include logistics, distribution, and call centres.
