The Müritz National Park (German: Müritz-Nationalpark) is a national park situated roughly in the middle between Berlin and Rostock, in the south of the German state of Mecklenburg-Vorpommern. It extends over large portions of the Müritz lakeland in the district of Mecklenburgische Seenplatte. Müritz National Park was founded in 1990. The total area is 318 km². Near the city of Waren visitors can get information on the national park at the Müritzeum.

The National Park is divided into two separated areas, Müritz and Serrahn: The first, larger portion extends from the eastern shore of Lake Müritz to the town of Neustrelitz. The latter, smaller part is situated east of Neustrelitz. The landscape features of the park are made up from terminal moraine, sandur and lowlands. 65 % of the territory is covered with forest, 12 % by lakes. The remaining area is made up of swamps or meadows.

Lake Müritz has an area of 118 km², but only its eastern shore is part of the National Park. The towns of Waren and Neustrelitz are the closest towns. There are about 100 lakes in Müritz National Park, and many more smaller waterbodies, runs, ditches and brooks. The Havel rises in the Müritz section, close to the water divide between the Baltic and the North Sea.

A national park is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Although individual nations designate their own national parks differently (for example, see Martin Luther King, Jr. Memorial in the United States), an international organization, the International Union for Conservation of Nature (IUCN), and its World Commission on Protected Areas, has defined National Parks as its category II type of protected areas. While ideas for this type of national park had been suggested previously, the United States established the first such one, Yellowstone National Park, in 1872. The largest national park in the world meeting the IUCN definition is the Northeast Greenland National Park, which was established in 1974. According to the IUCN, there were 6,555 national parks worldwide in 2006 that meet its criteria.

In 1969 the IUCN (International Union for the Conservation of Nature and Natural Resources) declared a national park to be a relatively large area with particular defining characteristics. A national park was deemed to be a place
