The Citigroup Center (formerly Citicorp Center) is one of the ten tallest skyscrapers in New York City, United States, located at 53rd Street between Lexington Avenue and Third Avenue in midtown Manhattan. The 59-floor, 915-foot (279-m) building contains 1.3 million square feet (120,000 m²) of office space, and is one of the most distinctive and imposing in New York's skyline, thanks to a 45° angled top and a unique stilt-style base. It was designed by architect Hugh Stubbins Jr. for Citibank, and was completed in 1977. The building is currently owned by Boston Properties, and is the tallest building that bears the Citigroup name.

The roof of Citigroup Center slopes at a 45-degree angle because it was originally intended to contain solar panels to provide energy. However, this idea was eventually dropped because the positioning of the angled roof meant that the solar panels would not face the sun directly. To help stabilize the building, a tuned mass damper was placed in the mechanical space at its top. This substantial piece of stabilizing equipment weighs 400 tons (350 metric tons). The damper is designed to counteract swaying motions due to the effect of wind on the building and reduces the building's movement due to wind by as much as 50%. Citigroup Center was the first skyscraper in the United States to feature a tuned mass damper. The building features double-deck elevators, which are separated to serve only odd or even floors. The corporate headquarters of Citigroup, contrary to popular perception, are not located in the building, but across the street in 399 Park Avenue. In 2002, one of the columns was reinforced with blast resistant shields of steel and copper as well as steel bracing to protect the building due to the possibility of a terrorist attack.

- The building featured in the music video for Janet Jackson's "Runaway", in which she runs up the slanted roof.
