2 World Trade Center is a skyscraper being developed as part of the rebuilt World Trade Center complex in Manhattan, New York City. It will replace the original 2 World Trade Center, which was completed as part of the first World Trade Center in 1973 and subsequently destroyed during the September 11 attacks in 2001, and it will occupy the position of the original 5 World Trade Center. The foundation work was completed in 2013, though no construction has taken place since.

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.
