The National Park Service was established on August 25, 1916. Until that time, national parks and monuments were managed by various government agencies from the U.S. Forest Service (Department of Agriculture) to the Department of War. Today, the National Park Service manages more than 375 parks, monuments, recreation areas, and other units.

* All acreages listed are the parks' current size. Most were much smaller when they were originally established.
