List of the United States National Park System official units
The Official Units of the National Park System of the United States is the collection of physical properties owned or administered by the National Park Service.
As of 2019, there are official units of the National Park System; however, this number can be misleading. For example, Denali National Park and Preserve are 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. Furthermore, the NPS contributes resources to "affiliated areas" which do not fall under its administration, and these do not count toward the official list number. An example is Oklahoma City National Memorial.
These units are a subset of the areas in the United States National Park System, and nearly all participate in the national park passport stamps program. National Park System units are found in all 50 states, in the District of Columbia, and in the U.S. territories of Guam, the Northern Mariana Islands, American Samoa, the U.S. Virgin Islands, and Puerto Rico.
