The National Park System of the United States is the collection of physical properties owned or administered by the National Park Service. The collection includes all national parks and most national monuments, as well as several other types of protected areas of the United States.
As of January 2020, there are 419 units of the National Park System. However, this number is somewhat misleading. For example, Denali National Park and Preserve is counted as two units, since the same name applies to a national park and an adjacent national preserve. Yet Jean Lafitte National Historical Park and Preserve is counted as one unit, despite its double designation. Counting methodology is rooted in the language of a park's enabling legislation.
In addition to areas of the National Park System, the National Park Service also provides technical and financial assistance to several affiliated areas authorized by Congress. Affiliated areas are marked on the lists below.
The National Register of Historic Places (NRHP), which contains nearly 79,000 entries, is administered by the National Park Service. All historically significant park units are automatically included on the NRHP—i.e., all national historical parks and historic sites, national battlefields and military parks, and national memorials, as well as some national monuments.
National Park System units are found in all 50 states, in Washington, D.C., and in the U.S. territories of Guam, the Northern Mariana Islands, American Samoa, the U.S. Virgin Islands, and Puerto Rico.
Nearly all units managed by the National Park Service participate in the National Park Passport Stamps program.

Ten are distinct stand-alone official units of the National Park System, while nine others are merely areas of distinct management policies and land-use restrictions within a larger "national park and preserve" or "national monument and preserve" that are counted as two units of the National Park System by the National Park Service. Two other sites are areas of distinct management policies and land-use restrictions within a larger park (Oregon Caves National Monument and Preserve and Jean Lafitte National Historical Park and Preserve) but by statute are counted by the National Park Service as single units of the National Park System.
