List of largest protected areas

The World Database on Protected Areas (WDPA) is compiled and managed by the World Conservation Monitoring Centre, an executive agency of the United Nations Environment Programme. It uses the IUCN and CBD definitions of protected areas to determine whether a site should be included in the WDPA. The twenty largest protected areas in the October 2017 edition of the WDPA are listed below, in order of size as reported by the relevant data provider. All are marine protected areas except for Northeast Greenland National Park, which is mostly terrestrial but also has a marine component. Protected areas with multiple coterminous or overlapping designations (e.g. Northeast Greenland National Park and the corresponding Biosphere Reserve) are listed only once.
