About Eastern National

Eastern National, formerly known as Eastern National Park and Monument Association, is a 501(C)(3)
not-for-profit "cooperating association" that supports the National Park Service.

Currently, Eastern National is the cooperating association for over 150 national parks, and is partners with many other public trusts including the U.S. Forest Service, Army Corps of Engineers, and state and city park systems. Eastern National's role has expanded over the years, becoming the largest cooperating association in the United States. Since its incorporation in 1948, Eastern National has donated over $100 million to the National Park Service, in the form of direct donations and grants.

Through the years, Eastern National funds have purchased such critical items as land, artifacts, media for park libraries, period costumes for living history demonstrations and reenactments, signage and exhibits, facility renovations and upgrades, interpretive tools and programs, staff training programs, and much more. Donations have also funded archeological, historical, and cultural research programs which have had a direct impact on the parks and their interpretive programs.
