The United States Park Police is a unique organization within the National Park Service.

It is the oldest NPS component, predating its adoptive parent by half a century (or more, some would argue).
Its personnel wear distinctive uniforms, perform specialized functions, and are regularly assigned to a small minority of national parklands.
