Tower Fifth is a skyscraper proposed for Midtown Manhattan in New York City.

The developer, Macklowe Properties, has completed other projects including the redevelopment of the General Motors Building and construction of 432 Park Avenue.

[6] If completed as planned, it will become the fifteenth tallest building in the world[7] and the tallest in New York City by roof height,[6] surpassing the nearby Central Park Tower by about 6 ft (2 meters).

The facade of Tower Fifth is designed by Gensler and would feature a closed cavity system that reduces solar heat gain by 70 percent.

The massing of the structure is consistent for the bulk of the rise until it reaches a cantilevering observation deck consisting of multiple floors at the top.
