Adelphi is an unincorporated area and census-designated place in Prince George's County, Maryland. The population was 15,086 at the 2010 United States Census. It includes the communities of Adelphi Hills, Adelphi Park, 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. The Adelphi Mill is administered by the Maryland-National Capital Park and Planning Commission and continues to attract visitors and can be rented for special functions. During the 19th century, George Washington Riggs acquired much of the area northeast of Washington, D.C., as his Green Hill estate in the Chillum Manor district. 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.
Unlike its nearby neighbors Hyattsville and College Park, the area remained relatively undeveloped until immediately following World War II. At that time, subdivisions quickly developed. To distinguish it from the other neighboring unincorporated communities of Lewisdale and Langley Park, the growing subdivisions banded together in the mid-1950s and adopted the name "Adelphi" to reflect their commitment to the preservation of the historic mill of the same name. These subdivisions now include Adelphi Park, Buck Lodge, Chatham, Cool Spring Terrace, and White Oak Manor. A community focal point originally developed in the late 1950s is the Adelphi Pool.
In 1971, the Harry Diamond Laboratories was established on 137 acres (0.55 km2) in the northern part of Adelphi. That facility continues as the Adelphi Laboratory Center, Army Research Laboratory (ARL), the U.S. Army's corporate research laboratory. Other adjacent federal facilities include the National Archives at College Park and headquarters of the Food and Drug Administration.

The main shopping centers that serve the Adelphi neighborhood are the Adelphi Shopping Center, Adelphi Plaza, and Metzerott Plaza.
Adelphi Shopping Center
The Adelphi Shopping Center is located at the corner of University Boulevard and West Park Drive. From 1955 to July 25, 2010, the Adelphi Shopping Center was home to the original Ledo Restaurant, an Italian restaurant, famous for its specialty pizzas. On July 25, 2010, the Original Ledo Restaurant closed its doors in the Adelphi Shopping Center and reopened its new location in Downtown College Park. The restaurant has been and continues to be a long time favorite by the University of Maryland students/faculty as well as by residents of the Adelphi and College Park communities. In the middle of 2011, the El Amate Texas Mexican Resturant/ Bar took over Ledo's former space in the Adelphi Shopping Center.
Also, interestingly after Ledo's, the Adelphi Shopping Center was home to a Jumbo Food Store on October 1, 1958. The Jumbo Food Store was later converted into a Shoppers Food Warehouse store in the late 1980's by the same owners that started the Jumbo Foods store. In 1994, the Shoppers Food Warehouse in the Adelphi Shopping Center managed to survive a fire. The Shoppers Food Warehouse used the fire as an opportunity to modernize its store's interior. However, seventeen years later in Spring 2011, the Shoppers Food Warehouse closed its doors in the Adelphi Shopping Center. Shoppers' business in the area began to slowly take a toll over the past two decades due to change in demographics in the area. There was a large flight of middle class Caucasians and African Americans leaving the area, while a growing number of Hispanics began moving into the area. Shoppers had trouble adapting to this change in demographics. It could not compete with the nearby MegaMart Supermarket, in terms of the high quality and diverse varieties of fruits, vegetables, Latin American bakery items, and specialty Latin American grocery items the store could offer. In addition to specialty Latin American groceries, MegaMart was also able to offer similar food products American supermarkets offer; such as Meat, Milk, Cereal, Soda, Ice Cream, Yogurt, and Classic American Snacks, such as Lay's Potato Chips, Oreos, Ritz Crackers, and Fritos. MegaMart offered these items at a fraction of Shoppers' prices for these similar grocery items. This completely reduced the need for residents in the area to shop at the Shoppers Food Warehouse. One year after Shoppers' departure in 2012, the D.C. MegaMart chain opened up a second supermarket in Shopper's former location, called "MegaFarmer's Supermarket" though the chain already had a store across the street at the Adelphi Plaza. In addition to Ledo's and Shoppers, the Adelphi Shopping Center was also home to a Loch Lomond Bakery Store, the Asian Carry Out Restaurant, SunTrust Bank, Haircut 2000 barber shop, H&R Block store, Cricket Wireless store, and Advanced Auto Parts store. These stores are still operating in the Adelphi Shopping Center today.
The Adelphi Plaza is another shopping center that serves the Adelphi neighborhood. It is not too far away from the Adelphi Shopping Center. As a matter of fact, the Adelphi Plaza is right next to the Adelphi Shopping Center on the same side of University Boulevard, but a little more west. The Adelphi Plaza contains a MegaMart Supermarket, Sabor Latino Restaurant, La Casa De La Musica, McDonald's Fast Food Restaurant, King Kong Chinese Restaurant, Shell Gas Store, and BP Gas Store.
Metzerott Plaza is the third shopping center that serves the Adelphi neighborhood. It is located at the corner of Adelphi Road and Riggs Road. Metzerott Plaza used to have a Safeway Food and Drug Store, McDonald's, and a Bustin' Suds Laundromat. These stores closed their doors in the Metzerott Plaza Shopping Center on November 2, 2006. A Bestway Latin American Supermarket has occupied Safeway's place in the Metzerott Plaza; since Safeway's departure. Today, Metzerott Plaza consists of a Rite Aid Pharmacy, Golden Bull Restaurant, small Seven Eleven Convenience Store, Bank of America, Popeyes Fast Food Restaurant, Basil's Pizza Shop, SkyLake Laundromat, Western Union, and Bestway Supermarket.
