Trump Tower is a 58-floor, 664-foot-tall (202 m) mixed-use skyscraper at 721–725 Fifth Avenue, between 56th and 57th Streets, in Midtown Manhattan, New York City. Trump Tower serves as the headquarters for the Trump Organization.

Donald Trump—the son of Fred Trump, a real estate developer in Queens and Brooklyn—had envisioned building a tower at 56th Street and Fifth Avenue in Manhattan since childhood, but only formulated plans to develop the site in the mid-1970s, when he was in his thirties. At the time, the Bonwit Teller flagship store, an architecturally renowned building built in 1929, occupied the lot. The site was next to Tiffany's flagship store on 57th Street, which Trump considered the city's best real-estate property. Approximately twice every year, Trump contacted Bonwit Teller's parent company, Genesco, to ask whether they were willing to sell Bonwit Teller's flagship store. Trump said the first time he contacted Genesco, "they literally laughed at me".

In February 1979, Genesco sold off many of the Bonwit Teller locations to Allied Stores, and sold the brand's flagship building to the Trump Organization. Trump also bought the air rights around Tiffany's flagship store to prevent another developer from tearing down the store and building a taller building.
