Lorentz National Park is located in Papua, Indonesia formerly known as Irian Jaya (western New Guinea). With an area of 25,056 km2 (9,674 mi2), it is the largest national park in South-East Asia. In 1999 Lorentz was declared a World Heritage Site by UNESCO.

An outstanding example of the biodiversity of New Guinea, Lorentz is one of the most ecologically diverse national parks in the world. It is the only nature reserve in the Asia-Pacific region and the world to contain a full altitudinal array of ecosystems ranging through marine areas, mangroves, tidal and freshwater swamp forest, lowland and montane rainforest, alpine tundra, and equatorial glaciers.

At 4884 meters, Puncak Jaya (formerly Carstensz Pyramid) is the tallest mountain between the Himalayas and the Andes.

Lorentz National Park has 630 documented species of bird (around 95% of the total number of bird species in Papua) and 123 mammalian species. Birds include two species of cassowary, 31 dove and pigeon species, 500 species of cockatoo, 60 species of kingfisher and 145 species of sunbird. 

Lorentz Park contains many unmapped and unexplored areas, and is certain to contain many species of plants and animals as yet unknown to Western science. Local communities' ethnobotanical and ethnozoological knowledge of the Lorentz biota is also very poorly documented.
