The National Park Service (NPS) is an agency of the U.S. Department of the Interior responsible for managing and maintaining national parks, monuments, historical sites, and other designated properties. Established on August 25, 1916, by the National Park Service Organic Act, the NPS was created to preserve the natural and cultural resources and values of the National Park System for the enjoyment, education, and inspiration of current and future generations. The act mandated the agency "to conserve the scenery and the natural and historic objects and wildlife therein, and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations". The NPS manages 433 units covering over 85 million acres in all 50 states, the District of Columbia, and U.S. territories.
The NPS is led by a Director, who is nominated by the U.S. President and confirmed by the Senate. As of March 2026, President Trump nominated Scott Socha to serve as the next director. However, the nomination is pending confirmation by the U.S. Senate. Recent news indicates the NPS is facing challenges, including staff shortages and budget cuts. In 2024, the National Park Service recorded 331.9 million recreation visits. The Great Smoky Mountains National Park was the most visited national park.
