Hawk Mountain Sanctuary is a wild bird sanctuary in Albany Township and East Brunswick Township, located along the Appalachian flyway in eastern Pennsylvania. The sanctuary is a prime location for the viewing of kettling and migrating raptors, known as hawkwatching, with an average of 20,000 hawks, eagles and falcons passing the lookouts during the late summer and fall every year. The birds are identified and counted by staff and volunteers to produce annual counts of migrating raptors that represent the world's longest record of raptor populations. These counts have provided conservationists with valuable information on changes in raptor numbers in North America.

The property was listed on the National Register of Historic Places in 2022.

Setting
The Sanctuary is located on a ridge of Hawk Mountain, one of the Blue Mountain chain. The Visitor Center houses a shop and facilities with parking nearby. A habitat garden next to it is home to native plants that are protected by a deer fence. The  Lookout Trail runs from the Visitor Center to a number of raptor viewing sites along the ridge, the most popular being the close by South Lookout (elevation ) and the North Lookout (elevation ) with a 200 degree panoramic view that extends to . Nine trails of varying difficulty are available to hikers and linked to the Appalachian Trail.

Located in the sanctuary is Schaumboch's Tavern, listed on the National Register of Historic Places in 1979.

History 
The area was a popular site for shooting hawks, either for sport or to prevent depredations on domestic fowl or game birds. In 1934, Rosalie Edge leased  of property on Hawk Mountain and hired wardens to keep the hunters away. The wardens were Maurice Broun and his wife Irma Broun, bird enthusiasts and conservationists from New England. Almost immediately, there was a noticeable recovery in the raptor population. In 1938, the Hawk Mountain Sanctuary Association was incorporated as a non-profit organization in Pennsylvania, and Edge purchased the property and deeded it to the association in perpetuity.

In 1965, the sanctuary was designated a National Natural Landmark, and in 2022 it was listed on the National Register of Historic Places.

Famous visitors to the sanctuary include Rachel Carson.

Through Sarkis Acopian's philanthropy, the sanctuary was able to open the Acopian Center for Conservation Learning in 2001, where students come from all over the world to participate in work-study internships, learning about ornithology, environmental science, biology, and related fields.
