Northeast Greenland National Park is the world's largest national park and the ninth largest protected area on Earth. It should come as little surprise, then, that it's also bigger than most countries, covering an impressive 972,000 square km (375,300 square miles).

The largest park in the world is the Northeast Greenland National Park, which encompasses a staggering 972,000 square kilometers (375,000 square miles). Established in 1974 and expanded in 1988, this park is larger than most of the world's countries and covers roughly 45% of the island of Greenland. It is a true Arctic wilderness, home to polar bears, musk oxen, walruses, and various species of arctic birds. Because of its extreme northern location and harsh environment, the park has no permanent human inhabitants, save for a small number of military personnel at the Daneborg headquarters and researchers at remote stations. If you are looking for the largest urban park, the title often goes to Chugach State Park in Anchorage, Alaska, which covers nearly 500,000 acres, though Table Mountain National Park in Cape Town and Margalla Hills in Islamabad are also massive urban-adjacent protected areas. However, in terms of sheer geographical scale, the vast, ice-covered expanse of Northeast Greenland remains the undisputed champion of protected terrestrial areas.
