Oxon Hill is an unincorporated area and census-designated place (CDP) in southern Prince George's County, Maryland, United States.

[2] Oxon Hill is a close suburb of Washington, located southeast of the downtown district and east of Alexandria, Virginia.

In 2008, the 300-acre (120 ha) National Harbor development on the shore of the Potomac River opened in Oxon Hill; it has since become a CDP of its own.

The current Manor is now owned by the Maryland-National Capital Park and Planning Commission and is used for cultural activities, as well as being rented for weddings and special events.

Prior to that date, traffic backed up into Oxon Hill daily for decades as 250,000–300,000 vehicles a day crossed the Wilson Bridge.

Oxon Hill's two principal shopping centers ("Rivertowne", built about 1985 and "Eastover", built about 1955[7][8]) attract neighborhood customers as well as shoppers from nearby Southeast Washington, D.C. Eastover, located at the D.C./state line, is a hub of many bus routes, some of them operating 24 hours a day, and has a Prince George's County Police station.

[12] Rosecroft Raceway (founded in 1949) and Henson Creek Golf Course (a nine-hole course) are among Oxon Hill's recreational attractions; Rosecroft Raceway offers a limited number of harness horse racing dates throughout the year, as well as betting on select televised simulcast races from around the country (per article in Washington Post, May 20, 2010).

Oxon Hill is also the location of National Harbor, a major development on the Potomac River: a 7,300,000-square-foot (680,000 m2) mixed-use community including 2,500 residential units, 4,000 hotel rooms, 1,000,000 square feet (93,000 m2) of retail, upscale dining, and entertainment, and 500,000 square feet (46,000 m2) of class-"A" office space, along with one of the largest marinas on the Potomac and the 2,000 room Gaylord National Resort & Convention Center, the largest hotel in the entire Washington area.

Both are located in the former John Hanson Junior High School building, which is next door to the main Oxon Hill post office.

Originally built in 1967,[24] the Oxon Hill Library Branch contains the Sojourner Truth Room, an African American research collection.

Other topics are antislavery and slavery tracts, literary criticism, and the history of African Americans in Maryland and Prince George's County.

Prince George's County Police Department District 4 Station in Glassmanor CDP, with an Oxon Hill postal address, serves the community.
