The United Nations Headquarters（联合国总部大厦） is a distinctive complex in New York City that has served as the official headquarters of the United Nations since its completion in 1950. It is located in the Turtle Bay neighborhood, on the east side of Midtown Manhattan, on spacious grounds overlooking the East River (东河).
The United Nations has three additional, subsidiary, regional headquarters or headquarter districts. These are located in Geneva (Switzerland), Vienna (Austria), and Nairobi (Kenya).
Though it is in New York City, the land occupied by the United Nations Headquarters is considered international territory（国际领土）, and its borders are First Avenue on the west, East 42nd Street to the south, East 48th Street on the north and the East River to the east.
The United Nations Headquarters complex was constructed in New York City in 1949 and 1950 beside the East River, on 17 acres (69,000 m2) of land purchased from the foremost New York real estate developer（房地产开发商） of the time, William Zeckendorf. Nelson Rockefeller arranged this purchase, after an initial offer to locate it on the Rockefeller family（洛克菲勒家族） estate of Kykuit was rejected as being too isolated from Manhattan. The $8.5 million purchase was then funded by his father, John D. Rockefeller, Jr., who donated it to the City.

著名的联合国大厦(The United Nations)，550英尺(约167.64米)高，由一组建筑师花了六年时间设计完成。总部由四幢大楼组成：大会堂、会议大厦、39层高的秘书处大楼和达格•哈马舍尔德图书馆。
四个建筑物构成的联合国总部沿着East River横跨了第42大街到第48大街的整个地区。在此地总共有5000多名联合国工作人员。参观时间是每天9:00至16:45，每隔15分钟一次，参观所需时间大约45分钟。拥有西班牙语、法语、德语、俄语、汉语及日语导游。禁止穿着无袖上衣及短裤进入。一月至二月的周六、周日不可参观。最好的地方当属地下一层购物中心，这里陈列着世界各国的艺术品供购买并且免税。只有在这里的邮局才可发行的每年五套邮票十分受欢迎。
在联合国大楼的1楼内设有服务台，有 20 种语言可供选择，要听普通话亦可，这个大厅内设有许多各会员国赠送的艺术品，可以好好地欣赏一番，另外，千万不要错过楼下的礼品部门，里面有世界各国的特色娃娃。
有票的人都可以参加联合国大会和理事会的会议——开会时间在上午10点半至下午3点半之间。领票是根据先到先拿的原则，不收费。
