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

In 1924, they erected an 18,000-square-foot (1,700 m2), 28-room Georgian Revival mansion, designed by architect George Oakley Totten Jr., at a cost of $100,000.

[8] During the late 1930s-early 1940s, Leander McCormick-Goodhart, son of Frederick and Nettie, served as personal assistant to Ambassador Lord Lothian and supervisor of American Relief to Great Britain through the British embassy.

[9] As a result, the Langley Park estate became a regular site of social activities related to the British embassy including hosting the regular games of the Washington Cricket Club and, in June 1941, a British Relief Country Fair.

[10][11] The estate was first subdivided during and immediately after World War II, and was developed as a planned community by Pierre Ghent & Associates of Washington, D.C.

[18] That same year, 60 percent of the school population of 610 students was foreign born from 45 different countries and spoke 27 languages.

[19] In 1955, Langley Park was "the fastest growing trade area in Metropolitan Washington", with 200,000 people located within a 3-mile (4.8 km) radius.

[22] During the 1980s, Hispanic and Caribbean immigrants from countries such as El Salvador, Mexico, Guatemala, Colombia, Bolivia, Peru, Jamaica and elsewhere in the West Indies led a new wave of migration into the community.

In addition, Asian and African immigrants from places like Vietnam, India, Ethiopia and Nigeria settled into the area.

It proved to be an attractive locale for immigrants due to the availability of affordable housing that could also accommodate families.

The integration of these new groups into Langley Park reflected a larger trend of increased migration to the Greater Washington area during the 1980s and 1990s.

Residents in the 14th Avenue and Kanawha Street area in particular were subjected to "open air drug markets" and other criminal activity.

Apartment complexes, under new management, initiated safety measures to discourage drug activity such as installing new lighting, security doors and maintaining general upkeep of their properties.

By 1991, officials were taking note of an increase in illegal immigrants from Central America, and day laborers were beginning to become a common sight on area streets.

[25] The community is bordered by University Boulevard to the south, the Northwest Branch Anacostia River to the north, Phelps Road to the east, and the Prince Georges County–Montgomery County line to the west.

While most of the Langley Park neighborhood contains the Hyattsville ZIP Code of 20783, there is a small portion of Langley Park located west of New Hampshire Avenue (MD 650), but east of the Prince George's County–Montgomery County line, which contains the Silver Spring ZIP Code of 20903.

[34] Prince George’s County Police Department's District 1 serves Langley Park;[35] its station is in Hyattsville.

[38] One station will be at New Hampshire Avenue and University Boulevard, which was named one of the most dangerous intersections in Maryland for pedestrians to cross.

The Purple Line, which will connect to the Washington Metro, Amtrak and MARC, is under construction as of 2022 and is scheduled to open in 2026.

At each of the two corners of the New Hampshire Avenue / University Boulevard intersection is a large strip shopping center.

Langley Park-McCormick entered into the Title I program due to the low income statuses of many of its students.

[45] In 2001, there were 750 students, with about 33% of them being in the "English for Speakers of Other Languages" (ESOL) program,[46] and over 90% qualifying for free or reduced lunches.

[48] In 2013 the percentages of four those schools' students living in Langley Park were 82% (for Jones), 72% (for Cool Spring), 32% (for Buck Lodge), and 23% (for High Point).

[58] Langley Park of the early 1960s is featured in the short story "Blue Divisions" by Cuban-American author Alfredo Franco.
