Isle Royale National Park is an American national park consisting of Isle Royale – known as Minong to the native Ojibwe – along with more than 400 small adjacent islands and the surrounding waters of Lake Superior, in the state of Michigan.

Isle Royale is 45 mi (ca. 72 km) long and 9 mi (ca. 14 km) wide, with an area of 206.73 sq mi (535.4 km²), making it the fourth-largest lake island in the world. In addition, it is the largest natural island in Lake Superior, the second-largest island in the Great Lakes (after Manitoulin Island), the third-largest in the contiguous United States (after Long Island and Padre Island), and the 33rd-largest island in the United States.

Isle Royale National Park was established on April 3, 1940, then additionally protected from development by wilderness area designation in 1976, declared a UNESCO International Biosphere Reserve in 1980, and added to the National Register of Historic Places in 2019 as the Minong Traditional Cultural Property. The park covers 894 sq mi (2,320 km²), with 209 sq mi (540 km²) of land and 685 sq mi (1,770 km²) of surrounding waters.

The park's northern boundary lies adjacent to the Canadian Lake Superior National Marine Conservation Area along the international border. With 25,894 visits in 2021, it is the seventh least-visited National Park in the United States.

In 1875, Isle Royale was set off from Keweenaw County, as a separate county, "Isle Royale County". In 1897, the county was dissolved, and the island was reincorporated into Keweenaw County. The highest point on the island is Mount Desor at 1,394 ft (ca. 425 m), or about 800 ft (ca. 244 m) above lake level.

Isle Royale is within about 15 mi (ca. 24 km) from the shore of the Canadian province of Ontario and adjacently, the state of Minnesota (near the city of Thunder Bay), and is 56 mi (ca. 90 km) from the Michigan shore, on the Keweenaw Peninsula, itself part of Upper Peninsula. There are no roads on the island, and wheeled vehicles or devices, other than wheelchairs, are not permitted. Rock Harbor has wheeled carts available to move personal belongings from the Rock Harbor marina to the cabins and hotel. Also, the National Park Service employs tractors and utility terrain vehicles to move items around the developed areas at Windigo, Rock Harbor, and Mott Island.
