'''National Park Service rangers''' are among the uniformed employees charged with protecting and preserving areas set aside in the National Park System by the United States Congress and the President of the United States. While all employees of the agency contribute to the National Park Service mission of preserving unimpaired the natural and cultural resources set aside by the American people for [[future generations]], the term "[[park ranger]]" is traditionally used to describe all National Park Service employees who wear the uniform. Broadly speaking, all National Park Service rangers promote [[stewardship]] of the resources in their care—either voluntary stewardship via [[heritage interpretation|resource interpretation]], or compliance with [[statute]] or [[regulation]] through [[law enforcement]]. These comprise the two main disciplines of the ranger profession in the National Park Service.

Law enforcement rangers, or protection rangers, are uniformed federal law enforcement officers with broad authority to enforce federal and state laws within NPS sites. The NPS commonly refers to law enforcement operations in the agency as ''visitor and resource protection''.

In most NPS units, law enforcement rangers are the primary police agency.<ref>{{Cite web|url=https://www.law.cornell.edu/uscode/text/54/102701|title=54 U.S. Code § 102701 - Law enforcement personnel within System|website=Legal Information Institute|language=en|access-date=2019-12-31|archive-date=August 4, 2020|archive-url=https://web.archive.org/web/20200804045205/https://www.law.cornell.edu/uscode/text/54/102701|url-status=live}}</ref> The NPS also employs special agents who conduct more complex criminal investigations. Rangers and agents receive extensive police training at the [[Federal Law Enforcement Training Center]] and annual in-service and regular firearms training.
