American University Park is a neighborhood of Washington, D.C., named for the American University. AU Park, as it is often abbreviated, is situated against the Maryland border in the Northwest quadrant, bounded by Massachusetts, Wisconsin, Nebraska, and Western Avenues. Tenleytown and Friendship Heights lie to the east, Embassy Row to the southeast, and Spring Valley to the southwest. Politically, it is part of Ward 3 and Advisory Neighborhood Commission 3E.

The American University is a private federally chartered research university in Washington, D.C. Its main campus spans 90 acres on Ward Circle, mostly in the Spring Valley neighborhood of Northwest D.C. AU was chartered by an Act of Congress in 1893 at the urging of Methodist bishop John Fletcher Hurst, who sought to create an institution that would promote public service, internationalism, and pragmatic idealism. AU broke ground in 1902, opened as a graduate education institution in 1914, and admitted its first undergraduates in 1925. Although affiliated with the United Methodist Church, religious affiliation is not a criterion for admission.
