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 August 2024, there are 431 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 typically based on the language of a park's authorizing legislation.

Although the designations generally reflect sites' features, all units of the system are considered administratively equal and with few exceptions the designations themselves do not define their level of protection. Each site has a management plan consistent with its ecological, historic, and recreational resources and its 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.

National Park System units are found in all 50 states, the District of Columbia, and the U.S. territories of Guam, American Samoa, the U.S. Virgin Islands, and Puerto Rico. The territory of the Northern Mariana Islands has an affiliated area but not an official NPS unit.

Nearly all units managed by the National Park Service participate in the National Park Passport Stamps program.

There are 63 officially designated national parks in the United States and its dependent areas, as of 2021. The national parks are considered the "crown jewels" of the system and are typically larger than other areas, including a variety of significant ecological and geological resources.

There are 21 national preserves in the United States, 19 of which are counted by the National Park System as official units. Ten are stand-alone official units, while eleven others are designated areas where hunting or grazing is permitted as part of a larger "national park and preserve" or "national monument and preserve". Nine of those are counted as separate units, while Oregon Caves National Monument and Preserve and New River Gorge National Park and Preserve are single units (there is no functional difference). Jean Lafitte National Historical Park and Preserve is not officially a national preserve but has similar management policies, while Salt River Bay National Historical Park and Ecological Preserve is unrelated.

In addition, there are sites where the NPS is authorized to provide financial and technical assistance to local authorities for interpretive or educational purposes, but do not have the right to acquire land or have a say in land use or zoning. These include the 55 National Heritage Areas, as well as National Commemorative Sites such as Quindaro Townsite or the Kennedy-King National Commemorative Site. There are also various administrative groups of listed parks, such as Manhattan Sites, National Parks of New York Harbor, and Western Arctic National Parklands. The NPS also owns conservation easements (but not the land itself) for part of the area called the Green Springs National Historic Landmark District.
