The largest protected areas – those exceeding an area of 250,000 square kilometres – are listed below in order of total area protected.[3] All are marine protected areas except for Northeast Greenland National Park – which is mostly terrestrial but also has a marine component – and three entirely terrestrial biosphere reserves in Brazil. Protected areas with multiple coterminous or overlapping designations (e.g. Northeast Greenland National Park and the corresponding Biosphere Reserve) are listed only once.
Currently, Marae Moana is the largest protected area in the world with a total area larger than Mexico (1,964,375 km2).
