Quttinirpaaq National Park is located on the northeastern corner of Ellesmere Island in the Qikiqtaaluk Region of Nunavut, Canada. It is the second most northerly park on Earth after Northeast Greenland National Park. In Inuktitut, Quttinirpaaq means "top of the world". It was established as Ellesmere Island National Park Reserve in 1988, and the name was changed to Quttinirpaaq in 1999, when Nunavut was created, and became a national park in 2000.
The reserve covers 37,775 km², making it the second largest park in Canada, after Wood Buffalo National Park.
The park is remarkable for its extensive glaciers and ice caps, desert-like conditions, and life forms that are uniquely adapted to the extreme polar environment. Only about 50 people visit the park each year.
