Melimoyu National Park is a protected area of Chile in the comuna of Cisnes, in the Aysén Region.

The land for the creation of the park was assembled from public lands and estates donated by Tompkins Conservation, an organization founded by American conservationists Kristine and Douglas Tompkins, as part of a collaborative project to create a "National Parks of Patagonia Network".

[6] The park and its buffer zone is surrounded by Corcovado, Queulat and Isla Magdalena national parks, as well as the marine protected area named Pitipalena Añihué, located around the mouth of the Palena River.

[7] The territory where the park is located has been described by several European explorers since the late 18th century when it was visited by José de Moraleda.

Its main landmark, the Melimoyu volcano, serves as an aid for navigation on the Moraleda Channel, which was also described by captain Robert FitzRoy in his Narrative of the Surveying Voyages of H.M.S Adventure and Beagle.
