Headquarters of the United Nations in the context of "New York City"

United Nations specialized agencies are autonomous organizations working with the United Nations (UN) and each other through the structure of the United Nations Economic and Social Council at the intergovernmental level, and through the Chief Executives Board for Coordination (CEB) at the intersecretariat level.

One of the principal objectives of the UN is to solve economic, social, cultural and humanitarian issues through international cooperation. Several specialized agencies have been set up to achieve these goals, agencies which may or may not have been created by the UN, but were incorporated into the United Nations System by the United Nations Economic and Social Council acting under Articles 57 and 63 of the United Nations Charter. At present, the UN has in total 15 specialized agencies that carry out various functions on behalf of the UN. The specialized agencies are listed below.

Midtown Manhattan is the central portion of the New York City borough of Manhattan, serving as the city's primary central business district. Midtown is home to some of the city's most prominent buildings, including the Empire State Building, the Chrysler Building, the Hudson Yards Redevelopment Project, the headquarters of the United Nations, Grand Central Terminal, and Rockefeller Center, as well as several prominent tourist destinations, including Broadway, Times Square, and Koreatown. Penn Station in Midtown Manhattan is the busiest transportation hub in the Western Hemisphere.

Midtown Manhattan is the largest central business district in the world and ranks among the world's most expensive locations for real estate; Fifth Avenue in Midtown Manhattan has commanded the world's highest retail rents and had been ranked as the most expensive shopping street in the world before falling to second in 2024. Midtown Manhattan is the country's largest commercial, entertainment, and media center, and is also a growing financial and fintech center.

Downstate New York is a region that is generally described as consisting of the southeastern and more densely populated portion of the U.S. state of New York, in contrast to upstate New York, which comprises a larger geographic area with much sparser population distribution. While there is no widely agreed upon definition, the Downstate region is considered to consist of several subregions including New York City, Long Island, the Lower Hudson Valley and may also be considered by residents to include the Mid-Hudson Valley and Catskill Mountains areas. The New York State Department of Transportation (NYSDOT) defines its "Downstate Region" as including Dutchess and Orange counties, and the counties east and south of them in regions 8, 9 and 10 of the inset map. Both agencies and the general public use varying definitions of the boundary between Upstate and Downstate.

Despite being a small portion of the state's total land area, the Downstate region contains approximately two-thirds of New York's entire population. Its layout is largely urban and suburban, and constitutes New York State's portion of the New York metropolitan area, the world's largest urban landmass. New York City, the most populous city in the United States, is home to the United Nations headquarters, and has been described as the cultural, financial, and media capital of the world, as well as the world's most economically powerful city. The Upstate New York region, conversely, which forms the vast majority of the state's land area, contains more undeveloped land, including forests and farmland.

Headquarters (often referred to as HQ) notes the location where most or all of the important functions of an organization are coordinated. The term is used in a wide variety of situations, including private sector corporations, non-profits, military organizations, religious groups, sports leagues and so on. It usually implies a geographically dispersed organization with a clear hierarchical structure.

Turtle Bay is a neighborhood in New York City, on the east side of Midtown Manhattan. It extends from roughly 43rd Street to 53rd Street, and eastward from Lexington Avenue to the East River's western branch (facing Roosevelt Island). The neighborhood is the site of the headquarters of the United Nations and the Chrysler Building. The Tudor City apartment complex is next to the southeast corner of Turtle Bay.

Turtle Bay is named after a former cove of the East River. The neighborhood was originally settled as a Dutch farm in the 17th century, and was subsequently developed with tenements, power plants, and slaughterhouses in the 19th century. These industrial structures were largely demolished in the 1940s and 1950s to make way for the United Nations headquarters. Today, Turtle Bay contains multiple missions and consulates to the nearby United Nations headquarters.

42nd Street is a major crosstown street in the New York City borough of Manhattan, spanning the entire breadth of Midtown Manhattan, from Turtle Bay at the East River, to Hell's Kitchen at the Hudson River on the West Side. The street has several major landmarks, including (from east to west) the headquarters of the United Nations, the Chrysler Building, Grand Central Terminal, the New York Public Library Main Branch, Times Square, and the Port Authority Bus Terminal.

The street is known for its theaters, especially near the intersection with Broadway at Times Square, and as such is also the name of the region of the theater district (and, at times, the red-light district) near that intersection. The street also has a section of off-Broadway theaters known as Theatre Row.

The United Nations Secretariat Building is a skyscraper at the headquarters of the United Nations in the Turtle Bay neighborhood of Manhattan in New York City. It contains the offices of the United Nations Secretariat, the executive organ of the United Nations (UN). The building, designed in the International Style, is 505 ft (154 m) tall with 39 above-ground stories. It was designed by a group of architects led by Wallace Harrison. Although the building is located within the United States, the site is under UN jurisdiction, so the building is exempt from some local regulations.

The Secretariat Building is designed as a rectangular slab measuring 72 by 287 ft (22 by 87 m); it is oriented from north to south and is connected with other UN headquarters buildings. The wider western and eastern elevations of the facade are glass curtain walls, while the narrower northern and southern elevations are made of marble. The Secretariat Building has 889,000 sq ft (82,600 m) of space. There are press offices, staff rooms, and other functions on the lower stories. The Secretariat offices are placed on the upper stories, which were originally arranged in a modular layout. The building also features various pieces of artwork. The building's style has inspired the construction of other glass curtain wall buildings in Manhattan.
