One Court Square, also known as the Citigroup Building, is a 50-story (209.1 meters or 686 feet) office tower in Long Island City, Queens across the East River from Manhattan in New York City. It was completed in 1990 by Skidmore, Owings & Merrill LLP for Citigroup. The tower is the tallest building in New York City (and State) outside of Manhattan.[1] WNYZ-LP (also known as Pulse 87) broadcasts from the top of this building.

It is not to be mistaken for the Citigroup Center in Manhattan, which is across the street from Citigroup's main headquarters at 399 Park Avenue. The buildings are one subway stop away from each other along the IND Queens Boulevard Line (E M trains).
