Grand Portage is an unorganized territory in Cook County, Minnesota, United States, on Lake Superior, at the northeastern corner of the state near the border with northwestern Ontario.^[1] The population was 616 at the 2020 census.^[2] The unincorporated community of Grand Portage and the Grand Portage Indian Reservation are both located within Grand Portage Unorganized Territory of Cook County.

The adjacent Grand Portage National Monument, designated a National Monument in 1958, lies entirely within the boundaries of the Grand Portage Ojibwe Indian Reservation. The reconstructed depot celebrates fur trade and Ojibwe ways of life. The British North West Company built its inland headquarters at Grand Portage; the post was active until 1802.

Grand Portage is home to passenger ferries that provides access from the community to Isle Royale National Park, meaning Minnesota has access to the U.S. state of Michigan.

According to the United States Census Bureau, the unorganized territory has a total area of 192.5 sq mi (498.7 km²), of which 74.2 sq mi (192.2 km²) is land and 118.3 sq mi (306.5 km²) (61.46%) is water.

Minnesota State Highway 61 (Old U.S. Highway 61) serves as a main route in the area.

The community of Grand Portage is located 34 miles (55 km) northeast of the city of Grand Marais; and six miles (9.7 km) southwest of the Canada–US border.

The following unincorporated communities are located within Grand Portage Unorganized Territory:

• Grand Portage

Grand Portage has a humid continental climate that is prevalent throughout the state. Its version is significantly cooler in summers than more southerly areas and more severe in winters. Precipitation is dominant in summers, but can render some high volumes of snowfall in winter.

Beginning in the 17th century Grand Portage became a major center of the fur trade. See Canadian Canoe Routes (early). It was at the point where a major canoe fur trade route of the voyageurs left the great lakes. It was so named because the route began with a huge 9 mile portage.^[5] A portage is a place where the canoes and equipment are carried over land. The French established this trade with the Native Americans until the British took it over in the 18th century after the Seven Years' War. The North West Company established the area as its regional headquarters. Soon Grand Portage became one of Britain's four main fur trading posts, along with Niagara, Detroit, and Michilimackinac.^[6] Even after the American Revolutionary War and victory by the rebellious colonists, the British continued to operate in the area. Under the Treaty of Paris in 1783, Britain had to cede former territory to the United States, including this area.

Finally with the signing of the Jay Treaty in 1796 defining the northern border between Canada and the US, British traders planned to move from Grand Portage. They wanted to avoid the taxes the US put on their operations, in its effort to encourage American traders instead. In 1802 the traders planned to move north to create a new center, what they called Fort William. In 1803 following the Louisiana Purchase, in which the U.S. acquired the lands to the west of Grand Portage, the British finally moved from Grand Portage to the new post in Canada.^[7] The North West Company moved its headquarters northward to what they named Fort William. After British fur traders abandoned the area, it rapidly declined economically until fisheries and logging became popular in the 19th century.
