5 World Trade Center is a planned skyscraper at the World Trade Center in Lower Manhattan, New York City. The site is across Liberty Street, to the south of the main 16-acre (6.5 ha) World Trade Center site. In February 2021 it was announced the new 5 World Trade Center will be developed in a joint venture between Silverstein Properties and Brookfield Properties. The proposed building shares its name with the original 5 World Trade Center, which was heavily damaged as a result of the collapse of the North Tower during the September 11 attacks and was later demolished.

The Survivors' Staircase was the last visible remaining original structure above ground level at the World Trade Center site. It was originally an outdoor flight of granite-clad stairs and two escalators which connected Vesey Street to the World Trade Center's Austin J. Tobin Plaza. During the September 11 attacks, the stairs served as an escape route for hundreds of evacuees from 5 World Trade Center, a 9-floor building adjacent to the Twin Towers. The staircase is now an important feature of the National September 11 Memorial & Museum.
