National parks of Sweden are managed by the Swedish Environmental Protection Agency (EPA) (Swedish: "Naturvårdsverket" ) and owned by the state.
 The goal of the national park service is to create a system of protected areas that represent all the distinct natural regions of the country.
 In 1909, Sweden became the first country in Europe to establish such parks when nine were opened following the Riksdag passing of a law on national parks that year.
 This was followed by the establishment of seven parks between 1918 and 1962 and thirteen between 1982 and 2009, with the latest being Kosterhavet National Park.
 There are currently 29 national parks in Sweden, comprising a total area of 731,589 hectares (1,807,796 acres); six more are scheduled to open by 2013.

 While the national reserves cover small areas of scientific significance with restricted access, the national parks also cover wetlands of Ramsar designated areas and BirdLife International inscribed bird areas.
 The largest of the national parks initially covered were the Cúc Phương National Park, the Cát Tiên National Park, and the Côn Đảo National Park which to start with were forest areas cum reserves or prohibited areas.

The national parks of England and Wales are areas of relatively undeveloped and scenic landscape that are designated under the National Parks and Access to the Countryside Act (2016).
 Despite their similar name, national parks in England and Wales are quite different from national parks in many other countries, which are usually owned and managed by the government as a protected community resource, and which do not usually include permanent human communities.
 In England and Wales, designation as a national park may include substantial settlements and human land uses which are often integral parts of the landscape, and land within a national park remains largely in private ownership.
Within England and Wales there are thirteen areas known as national parks, each administered by its own national park authority, a special purpose local authority, the role of which as set out in the Environment Act 1995 is: "to conserve and enhance the natural beauty, wildlife and cultural heritage of the National Parks."
 and "to promote opportunities for the understanding and enjoyment of the special qualities of the National Parks by the public."
 The national park authority for each park addresses these aims in partnership with other organisations, such as the National Trust.
 In cases where there may be conflict between the two purposes of designation, the first must take precedence under the Sandford Principle.
 The national park authorities also have a duty to foster the economic and social wellbeing of communities in pursuit of these purposes.
