Glassmanor is an unincorporated community and census-designated place in Prince George's County, Maryland, in the United States. As of the 2010 census, it had a population of 17,295. Prior to 2010, the United States Census Bureau had placed Glassmanor and the adjacent community of Oxon Hill in the "Oxon Hill-Glassmanor" census-designated place for statistical purposes.
The original Glassmanor apartments were built about 1950 by the Glassman company just outside the border of southeast Washington, D.C. In the mid-1950s the Eastover shopping center was built across the highway, followed by other adjoining apartment projects in the 1960s. U.S. Senator George McGovern, who was the Democratic Party's presidential candidate in 1972, lived briefly in Glassmanor while a freshman congressman. The area has undergone tremendous demographic and social changes since that time.
