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

For the 1990 and 2000 censuses, the United States Census Bureau defined a census-designated place consisting of Oxon Hill and the adjacent community of Glassmanor, designated Oxon Hill-Glassmanor, for statistical purposes. As of the 2010 census, Oxon Hill was delineated separately and had a population of 17,722. Per the 2020 census, the population was 18,791.
