Adelphi is an unincorporated area and census-designated place in Prince George's County, Maryland, United States. The population was 14,998 at the 2000 census. It includes the communities of Adelphi Hills, Buck Lodge, Chatham, Cool Spring Terrace, and White Oak Manor. The unincorporated Adelphi community takes its name from the historic Adelphi Mill, established in 1796 along the Northwest Branch of the Anacostia River.
That estate included present day Adelphi. In the early 1920s, part of the area was acquired by Leander McCormick-Goodhart as part of his Langley Park estate. Labor organizer Mary Harris Mother Jones died in 1930, at the farm of Walter and Lillie May Burgess near Powder Mill and Riggs Roads in present day Adelphi. A marker was erected by the Maryland State Highway Administration commemorating Mother Jones at her death site.
