The National Association for Olmsted Parks (NAOP), established in 1980, is a coalition of design and preservation professionals, historic property and park managers, scholars, municipal officials, citizen activists and representatives of numerous Olmsted organizations around the United States. 

NAOP works to enhance the capacity of our national network of members and affiliates to preserve, rehabilitate and manage Olmsted landscapes in their communities and to carry the Olmsted vision into the future.  

NAOP encourages scholarship, publishes key reference materials, supports local park restoration, and provides technical assistance to preservation efforts.
